In their press release for the Mobi portable oxygen concentrator, ResMed CEO Mick Farrell had this to say:

"We have focused decades of patient-centered ResMed technology and design innovation into this POC. We've achieved great mobility, comfort and therapy quality in sleep apnea treatment with AirMini, the world's smallest PAP device. Mobi offers that same great balance to the many millions of people who rely on supplemental oxygen to enjoy their highest quality of life."

Although we don't know any of the unit specifications, we can expect a small and lightweight portable oxygen concentrator to be released by the end of this quarter according to ResMed's press release.

Did you know that living with COPD can make it more difficult to think, make decisions, and remember things? It's true; studies show that COPD can cause mild cognitive impairment, a condition that affects your memory and other mental functions.

Unfortunately, many people are unaware of, or underestimate, the effect that COPD can have on your brain. Because of this, many COPD patients experience mental decline without ever realizing that their disease could be the cause.

This is a shame, especially because COPD-related mild cognitive impairment is both treatable and preventable. But in order to avoid it or minimize its symptoms, you have to understand what it is and what is has to do with COPD.

That's why, in this post, we're going to explain how COPD causes mild cognitive decline and how to recognize it if you have it. We'll also explain what you can do to prevent COPD-related memory loss and how to treat it if it appears.

Many people with COPD have to deal with mild cognitive impairment at some point or another, and it's important to know what you can do about it and what to expect if it happens. That's why we've included a wealth of practical knowledge, helpful advice, and effective techniques in this guide to help you manage memory problems and other cognitive symptoms caused by COPD.

What Does Mild Cognitive Impairment Mean?

In general, mild cognitive impairment (MCI) is a condition that causes minor problems with memory, focus, problem-solving, and attention. It happens to many people as they age, but respiratory diseases like COPD can both trigger and accelerate the condition.

Many people who experience forgetfulness or worry their brain is not as “sharp” as it used to be are actually experiencing the symptoms of mild cognitive impairment. However, MCI is slightly worse than the normal changes to memory and cognition you'd expect to see with age alone.

{{cta('fa8abc2a-1e88-4fa3-82fd-1cb5b9ed43b2','justifycenter')}}

Mild cognitive impairment happens when the brain's cognitive functions are slightly lower than they should be. It can result from both temporary problems (e.g. oxygen deprivation) and permanent changes (e.g. structural damage) that happen to the brain.

Mild cognitive impairment is very common, affecting about 10-20 percent of people over the age of 65 and about 36 percent of people with COPD. Fortunately, it is a treatable, and sometimes even reversible, condition that can improve with diet, exercise, and other lifestyle changes.

It's important to note that the symptoms of mild cognitive impairment are often very subtle. Some people notice these symptoms on their own, but many don't recognize the signs of MCI until a friend or family member points it out.

Here are some of the most common signs and symptoms of COPD-related memory loss and MCI:

• Forgetting things like events and appointments often
• Forgetting words or struggling to come up with the right vocabulary more often
• Losing or misplacing things more often
• Feeling overwhelmed when faced with problems, making decisions, or making plans
• Difficulty understanding instructions or doing activities that require multiple steps
• Struggling to focus on simple tasks like reading, watching a movie, or having a conversation
• Difficulty finding your way around familiar places or environments
• Increased impulsive behavior or poor judgment

Sometimes, mild cognitive impairment is split into two distinct categories: memory-related or “amnestic” MCI, and MCI that affects thinking skills like decision making and completing tasks with several steps. Some people with MCI experience just one or two symptoms, while others experience a wider rage of cognitive problems.

In the words of Charles Emery, a COPD researcher from Ohio State University, “COPD-related cognitive impairment usually isn't noticeable to the untrained eye, but it can be a serious problem.” That's why people with COPD should be more aware of their risk for cognitive impairment and more familiar with what it looks like in everyday life.

Even if you don't realize it's happening, mild cognitive impairment can make daily living more difficult and have rippling negative effects. Even minor memory problems, like misplacing bills or forgetting to turn off the stove, can cause serious problems in everyday life.

Minor cognitive impairment can also make it difficult to manage your disease and keep track of your medications and other treatments. For example, it could cause memory problems that lead you to use your medications incorrectly or skip doses accidentally, making you more vulnerable to life-threatening exacerbations, quicker disease progression, and other disease complications.

Experiencing difficulties with memory and concentration can also cause you to feel frustrated and stressed, even if you aren't aware that your symptoms are caused by MCI. This can lead to mental disorders like anxiety and depression, especially if the condition is left untreated for too long.

Luckily, COPD-related cognitive impairment can be treated and managed to minimize the symptoms and its effect on your quality of life. With healthy lifestyle changes and proper treatment, you may even be able to regain some or all of the cognitive ability you've lost, especially if you catch it early on.

Importantly, early treatment for mild cognitive impairment can prevent future cognitive decline and more serious conditions like dementia. Because it often results from low blood oxygen levels, recognizing mild cognitive impairment can also alert you to other problems that you need to address in order to better manage your COPD.

The Relationship Between COPD and Memory Loss

At first, it might seem strange that COPD, which is primarily a respiratory disease, could cause mental deficiencies and memory problems. However, a variety of studies have confirmed that there is a direct link between lung function and cognitive decline.

Research from the Mayo Clinic, for instance, found that having COPD can double your risk for mild cognitive impairment, including memory loss. The risk is even higher for people with more advanced COPD and people who use supplemental oxygen therapy.

Some people experience general cognitive impairment that affects many areas of cognition, while others only experience difficulties in one or two areas. Specific cognitive abilities that tend to be affected are memory, information processing, attention, concentration, executive function, and self-control.

However, research also shows that people with COPD—even advanced COPD—only show very slight cognitive decline. According to one study, people with severe COPD scored, on average, just one point less than people who didn't have the disease on a 35-point scale of cognitive ability.

But even though this amount of cognitive decline might seem trivial, it is not something you should ignore. Mild cognitive impairment is enough to affect everyday life and impair your ability to manage your COPD.

That's why it's important to look out for even minor symptoms, especially since cognitive impairment is much more treatable in the early stages. Recognizing the earliest signs of MCI and taking them seriously is a necessary step toward making the changes that can minimize your symptoms and prevent more serious cognitive issues in the future.

How COPD Causes Cognitive Impairment

To understand why COPD causes cognitive impairment, you have to realize that COPD is not just a simple breathing disorder. It is a disease that causes inflammation, strains your heart, and starves your body of oxygen.

One of the key links between COPD and MCI is low blood oxygen levels, known as hypoxemia, which gets worse in the later stages of the disease. This lack of oxygen affects every organ in your body, but it is especially harmful to your heart and brain.

The brain is particularly sensitive to the effects of hypoxemia because it needs so much oxygen; the brain uses up a large amount of energy and needs a continuous flow of oxgen-rich blood in order to function. Because of this, low blood oxygen levels are particularly bad for your brain, and they can lead to brain hypoxia and cognitive impairment.

As a result, memory and cognition problems are much more common in people with more advanced and severe COPD. As the the lungs lose more and more of their ability to function, blood oxygen levels drop lower and more often than they did before, increasing the risk for cognitive symptoms.

However, hypoxemia is not the only reason that people with COPD experience mild cognitive impairment. Researchers believe that a lack of physical activity could also be a cause.

After all, many studies have shown a strong link between regular exercise and better cognitive function. There are many reasons for this, but improved cardiovascular health and circulation seems to play a major role.

Unfortunately, inactivity is a huge problem among people with COPD because their breathing symptoms make exercise very difficult. However, this lack of physical activity worsens COPD symptoms and causes the disease to progress more quickly.

The result is that it becomes harder for your body to supply enough oxygen to your brain and the rest of your body. This can lead to a variety of complications including cognitive impairment and dementia.

COPD also significantly increases your risk for cardiovascular disease for many different reasons, including hypoxemia, lack of exercise, and other disease complications. Cardiovascular disease is a well-known cause of cognitive impairment, in part because it causes poor circulation and damages the blood vessels in your brain.

COPD also causes chronic inflammation, which is a major risk factor for both heart disease and cognitive decline. Researchers believe this happens in part because long-term inflammation causes harmful changes to the blood vessels and tissues in the brain.

Researchers also suspect that a history of smoking—which the vast majority of people with COPD have—can make you more prone to mild cognitive impairment. One study showed, for instance, that MCI is much more common among people who have smoked, are currently smoking, or who are exposed to secondhand smoke for at least one hour per week.

COPD and Dementia

Studies show that both COPD and mild cognitive impairment can significantly raise your risk for dementia. That's because the same conditions that cause COPD-related cognitive impairment can also cause long-term damage to your brain.

Dementia is a general, umbrella term that is used to describe a variety of different types of cognitive decline. It is much more severe than mild cognitive impairment, but it often starts with MCI that gets worse and progresses to dementia over time.

Here are some of the major signs and symptoms of dementia:

• Memory loss that significantly interferes with daily life
• Difficulty completing simple, familiar tasks
• Confusion about dates, places, and how much time has passed
• Difficulty making plans, solving problems, and keeping up with responsibilities
• Difficulties with language, including speaking, writing, keeping track of conversations, and coming up with words
• Frequently misplacing things and forgetting about major events
• Social withdrawal, including giving up on hobbies or work

One of the main ways that COPD leads to dementia is by depriving your brain of oxygen. If your blood oxygen levels stay too low for too long, it can cause permanent damage to the blood vessels and tissues in your brain.

Other COPD-related symptoms and complications can also cause dementia, including chronic inflammation and heart disease. Basically, most of the conditions that can cause mild cognitive impairment have the potential to also cause dementia if they are severe enough or happen frequently enough.

However, it's important to note that, even though mild cognitive impairment and memory loss can be early signs of dementia, they don't necessarily mean that you will develop the disease. For many people with the condition, MCI stays stable or even improves with time.

The appearance of a normal brain versus a brain with severe Alzheimer's Disease, a form of dementia.

On the other hand, cognitive problems could be a sign that your COPD could cause, or is causing, serious damage to your brain. This is more likely to happen if your symptoms are severe or you suffer from frequent, severe hypoxemia.

If you have COPD and experience any symptoms of cognitive impairment, you need to be particularly diligent about managing your disease. By taking your medications, getting regular checkups, and living a healthy lifestyle, you can minimize your COPD symptoms and keep your blood oxygen levels high.

In many cases, it is possible to prevent COPD-related cognitive impairment and dementia with healthy living and proper COPD treatment. However, in order to do this, you might need to make some serious changes to your diet, your lifestyle, and how you manage your disease.

How to Prevent & Minimize Memory Loss Caused by COPD 

If you have COPD, the best way to prevent memory loss and cognitive impairment is to keep your heart and lungs in the best shape possible. That means managing your COPD properly and building healthy habits that help you keep your body strong.

If you already have mild cognitive impairment, these same methods may even help you reverse your cognitive symptoms. At the very least, making healthy changes can prevent more severe cognitive issues and make a noticeable difference in your health and quality of life.

In the next sections, we'll show you a variety of simple things you can do in your daily life to boost your cognitive ability and prevent cognitive decline. The earlier you take action the healthier your brain will be as you continue to manage your COPD.

Exercise Your Body

Exercise is an irreplaceable tool for keeping your heart, lungs, and brain healthy, especially if you have COPD. It can improve your circulation, improve your ability to breathe, and help your body get more oxygen to your brain.

Studies show that physical fitness reduces cognitive decline caused by aging and even improves general cognitive ability. Other studies on people with COPD even suggest that exercise alone can improve at least some symptoms of cognitive impairment.

On the other hand, lack of physical activity weakens your heart and lungs, worsens breathing problems, and leads to a variety of other health complications. Inactivity is particularly hard on your cardiovascular system, leading to high blood pressure, heart disease, and worsened hypoxemia.

That's why it is so vitally important to get regular physical activity if you have COPD. That means getting at least 20-30 minutes of exercise, including light to moderate-intensity aerobic exercise (e.g. walking, swimming, or jogging), at least 3-4 times per week.

While this might seem daunting at first, don't let it scare or discourage you. You don't have to jump in all at once; you can start small and work at your own pace.

You can start with simple, low-impact activities like walking, stretching, and doing light aerobic exercises. Anything you can do to add more physical activity to your schedule will help, including hobbies like gardening.

You could also join a gym, try a sport, or take regular walks in a park you enjoy nearby. There are many different ways to exercise, and all you have to do is find a few activities that you can stick with and enjoy.

Building the habit can be difficult, but it is certainly worth the effort it takes. It can not only significantly reduce your risk for cognitive decline, but it can also strengthen your heart, reduce your symptoms, and delay the progression of your COPD.

To help you get started, we've put together several guides full of practical tips and tricks for exercising with COPD. Take a look at any of them by clicking the links below:

• Hobbies and activities that are well-suited for people with COPD
• Exercises you can do at home to improve your COPD
• How Pulmonary Rehabilitation can improve your ability to exercise with COPD
• Breathing techniques you can use to reduce shortness of breath when you exercise

Exercise Your Brain

Much like physical exercise helps keep your body strong, mental exercise can help you keep your brain and cognitive functions strong. That's why it's important to keep your brain active as you age, and especially if you suffer from COPD.

Research shows that one of the best ways to do this is by learning new things and doing activities that require mental focus. These kinds of activities strengthen important neural pathways in your brain and can even improve your mental function.

Activities that exercise your brain include things like reading, social activities, and creative endeavors like writing and painting. Other hobbies like playing chess or doing puzzles can also help keep your brain sharp.

Studies show that learning a new skill like playing an instrument or speaking a new language is particularly effective at preventing cognitive decline. You can also pick up new skills by taking a class at a local college or community center, or by joining an activity club.

In general, making an effort to use your brain in new ways and learn new things can help you preserve your memory and cognitive skills as you live with COPD. It can also reduce your chances for developing more serious forms of cognitive impairment, including dementia.

Maintain a Healthy Weight

Being underweight or overweight is bad for your brain and can increase your risk for cognitive issues, including memory problems and MCI. Unfortunately, many people with COPD struggle to

COPD affects more than 11 million people in the US, both men and women alike. However, there are some noticeable differences between how men and women are affected by the disease.

For example, in recent years, significantly more women than men have been diagnosed with COPD. Men and women can also have different COPD symptoms, and gender can even affect how quickly the disease progresses and gets worse.

Other differences show up in the doctor's office, when doctors give different care to men and women with early symptoms of the disease. This results in many women having to wait longer to get tested and diagnosed for COPD.

While these differences don't apply to every man and woman, they play a role in many people's experiences with COPD. That's why, in this post, we're going to explain this gendered phenomenon and shed some light on why it matters.

In the following sections, we'll show you how COPD affects people of opposite sexes differently and take a closer look at where these differences come from. We'll also explain what these differences actually mean for men and women who have—or who are at risk for developing—COPD.

{{cta('43b79c5e-6bd6-4f02-ac27-2d038d20c146','justifycenter')}}

Differences Between COPD in Women and Men

It is possible for just about anyone to get COPD, but the disease does not affect all groups of people equally. This is reflected in the fact that people from different regions, nationalities, and sexes tend to get the disease at different rates.

However, this is not because the disease is fundamentally different in different types of people. Rather, it's because COPD is linked to secondary factors that tend to affect people in certain groups more than others.

In other words, when it comes to gender, COPD is associated with traits that tend to differ between men and women. Some of these differences are rooted in biology, but many of them are instead rooted in lifestyle and behavior.

In general, you can divide these differences into three main categories:

• Differences in risk, or how likely men and women are to develop COPD
• Differences in disease, or how COPD affects men's and women's bodies differently
• Differences in psychological symptoms

Differences in Risk

In general, women seem to have a higher risk of developing COPD than men. There are many potential reasons for this, but hormones and physical traits, like smaller airways in women, likely play a role.

This difference seems to be significant, especially among people who smoke tobacco, which is the number one cause of COPD. Research shows that women who smoke less than men actually tend to experience worse lung function decline.

This means that women who smoke are more likely to develop COPD and other lung diseases. Women are also more likely to develop symptoms of COPD at an earlier age.

Statistics show that about 58 percent of people who have COPD are women, and that women make up a slightly higher percentage—53 percent—of those who die from COPD. When you consider that about 15.5 million people in the US have been diagnosed with the disease, that adds up to about 9 million women and 6.5 million men with COPD.

However, this is a relatively recent phenomenon that is strongly tied to an increase in the number of women who smoke. Before the mid-1950's, it was largely men who smoked tobacco and later developed COPD.

Differences in Disease

A person's biological sex plays a role in how COPD affects their lungs. Because of this, men and women sometimes experience different COPD symptoms, and even differences in the overall severity of their disease.

For instance, COPD seems to progress more quickly in general in women than in men. This means that women with COPD often experience earlier and more severe lung function decline.

As a result, women's symptoms tend to be more severe—sometimes significantly more severe—and also tend to show up earlier in the disease. Women tend to experience worse shortness of breath, more frequent exacerbations, and are also more likely to die from COPD.

Men and women with COPD also tend to experience slightly different types of COPD (e.g. emphysema or chronic bronchitis), which can lead to different symptoms.

Men, for example, are more likely to have COPD dominated by emphysema, which tends to cause more fatigue-related symptoms. Women, on the other hand, tend to have worse chronic bronchitis, which causes more coughing and airway obstruction from mucus.

Additionally, while the death rate for men with COPD has fallen in recent years, the death rate for women has remained the same. While researchers aren't exactly sure why this is, declining smoking rates in men and quicker disease progression in women are the most likely culprits.

Women with COPD are also more likely to experience certain COPD complications like osteoporosis. This is partially due to the fact that osteoporosis is more common in women in general, but worse COPD symptoms in women also play a role.

Differences in Psychological Symptoms

Anxiety and depression are extremely common side effects of COPD. In fact, researchers estimate that up to 40 percent of people with COPD suffer from clinical depression while up to 20% suffer from clinical anxiety.

However, studies show that women with COPD are much more susceptible (PDF link) to these psychological disorders than men. This is likely influenced by a combination of several different factors, including the severity of COPD symptoms and high rates of anxiety and depression in women overall.

For instance, the fact that women experience worse symptoms and disease outcomes than men is enough on its own to explain much of this difference. More severe symptoms would naturally lead to more health-related stress, causing a higher incidence of anxiety and depression in women.

It is also worth noting that women, in general, tend to have significantly higher rates of anxiety and depression across the board. It is likely that the same factors that cause this general predisposition also apply to women with COPD.

Why Does Gender Affect COPD?

As you can see, there are a variety of important differences between how men and women are affected by COPD. However, while the facts and statistics are relatively straightforward, they don't exactly explain why these differences exist.

But before you can understand the reasons, you need to know how people develop COPD in the first place. Once you understand that, it's easier to see why certain groups of people (e.g. women) tend get COPD more often—and more severely—than others.

To put it simply, COPD is a breathing disorder caused by lung damage. It causes two main things to happen: it reduces the lungs' ability to absorb oxygen, and it narrows the airways so less air can flow through the lungs at a time.

This lung damage can be caused by many different things, namely diseases or substances that cause repeated irritation and inflammation in the lungs. For example, smoking, noxious chemicals, and other diseases like asthma can all cause COPD.

So, what does all this have to do with differences between the sexes? It's simple: COPD is caused by physical traits and patterns of behavior. Since men and women have different physical traits and different patterns of behavior, this naturally leads to differences in how likely men and women are to develop COPD.

For instance, in a biological sense, women tend to have smaller airways, which makes them more susceptible to damage. From a lifestyle perspective, however, men are more likely to work in occupations that could expose them to dangerous respiratory toxins.

Because of this, the differences between men and women with COPD are not always 100% consistent or clear cut. And, as men and women's habits and lifestyles change, so does their relative likelihood of developing COPD.

It is also important to realize that men and women do not always receive the same kind of medical care. This is another factor that could account for some of the differences we see between men and women with COPD.

Biological Differences

Men and women have different biological traits that affect their experiences with COPD. As we mentioned earlier, these differences can influence how likely someone is to develop COPD, what symptoms they have, and how quickly the disease progresses.

A person's biological sex influences both their physical traits and important hormones that regulate their health. Both of these factors can influence your likelihood of developing COPD as well as how your body responds to the disease.

The Effect of Airway Size

Studies show that women tend to have smaller airways than men, but not smaller lungs. This is a factor that could make some people more likely to develop COPD than others, and could partially explain why women seem to be more prone to COPD.

First of all, smaller airways could make women more sensitive to respiratory toxins like smoke. Because women have less total airway tissue, each bit of tissue gets exposed to proportionally more toxins when they breathe.

Compare a male smoker and a female smoker, for instance, who both have similarly-sized lungs but differently sized airways. When the man inhales smoke, the smoke will come into contact with a larger amount of airway tissue, since he has larger airways than the woman.

On the other hand, when the woman inhales smoke, the smoke comes into contact with a smaller surface area of tissue overall. However, she still inhales the same amount of smoke and toxins, meaning that the woman's airways are exposed to a higher “dose” of toxins per area than the man's airways.

This could explain part of the difference between men's and women's risks for developing COPD. Since women have smaller airways, they could be more prone to the damaging effects of cigarette smoke and other respiratory irritants.

The Influence of Hormones

Some researchers believe hormone activity could play a major role in how COPD progresses differently in women than in men. Having more estrogen, in particular, could make women's lungs more susceptible to damage from things like air pollution and smoke.

Researchers believe that estrogen worsens oxidative stress in the lungs, which could explain why smoking tends to affect women more severely. Oxidative stress occurs anytime the lungs and airways get inflamed by a respiratory irritant or infection.

Too much oxidative stress can damage the delicate tissue in the lungs, causing permanent scarring over time. COPD makes the lungs particularly sensitive, causing them to experience oxidative stress more frequently and severely.

Researchers have long noticed that women with COPD seem to have more lung scarring than men, and that the scarring tends to happen earlier on in the disease. This is true even for men and women with similar smoking histories who have lived with the disease for the same amount of time.

Because of this, women tend to have worse lung function and respiratory symptoms by the time they are diagnosed with COPD. The disease also progresses faster and causes death sooner in women than in men.

More recent studies have revealed that this effect could be caused by estrogen. Research shows that estrogen can significantly increase oxidative stress in the lungs, and experts believe this could make women more prone to both the risk factors and effects of COPD.

Since women produce more estrogen, their lungs and airways get exposed to extra oxidative stress any time they breathe in a respiratory irritant like smoke. This leads to worse and earlier airway tissue scarring in women with COPD compared to men.

This could also explain why women who smoke seem to experience quicker lung function decline than men. Estrogen could make their lungs more sensitive to respiratory irritants in general, putting women smokers at a higher risk for developing COPD and making women's COPD symptoms worse.

Genetic Diseases and Traits

Certain genetic traits might give some people a higher risk of developing COPD than others. However, while researchers know that genetics play some role in COPD, they still are not sure which genes those are or how they work.

It is certainly possible, for instance, that certain genes could predispose either men or women to develop COPD more easily. This is an ongoing area of COPD research, and more answers are likely to come in the future as researchers continue to untangle the genetic complexities of the disease.

Lifestyle Differences

On average, men and women tend to live different lifestyles, with different hobbies, occupations and household roles. While no man or woman is the same, there are, statistically, certain jobs, habits, and activities that either men or women are more likely to do.

These different lifestyles that men and women tend to choose have a significant effect on how likely they are to get exposed to harmful substances. And, as we know, how much someone is exposed to respiratory toxins is directly related to their likelihood of developing COPD.

Smoking

Cigarette smoking is the number one cause of COPD. As such, it is the most important factor in an individual person's risk for developing COPD.

One of the clearest ways to see this effect is to look at the changing rates of COPD among men and women over the years. In the mid-1900's, the vast majority of people with COPD were men; however, this changed in the late 1900's, as more women than men started to get diagnosed with the disease.

This change might seem strange until you realize that it is directly correlated to a major cultural phenomenon: more and more women started to smoke. Before then, a much larger percentage of smokers were men, and COPD was considered a male-dominated disease.

However, once this new generation of women smokers began to age, more and more cases of COPD began to show up in women. In fact, since 1980, the number of women who die from COPD every year has more than quadrupled in size (PDF link).

This made it clear that COPD wasn't a man's disease, but rather a smoker's disease, instead. Today, there is less of a gap between the percentage of men and women who smoke, and about 18 percent of men and 14 percent of women in the US are smokers.

This is the perfect example of how rates of COPD in a group can reflect lifestyles and habits that people in the group tend to share. After all, COPD used to be considered a “man's disease,” but this was almost entirely due to the fact that most cigarette smokers at the time were men, not any biological factor.

The Snowball Effect of Having Worse COPD Symptoms

People who experience worse COPD symptoms also have a reduced ability to exercise and do activities that require physical strength. This makes them less likely to get enough physical activity and more prone to sedentary lifestyle.

This can create a snowball effect that has significant consequences for both mental and physical health. Since women with COPD generally have worse lung function and symptoms, they are also more likely to succumb to this negative cycle.

The consequences can be serious: studies show that not getting enough exercise can significantly worsen both the physical and psychological symptoms of COPD. Studies on the general population also support the idea that physical activity is a powerful tool for combating anxiety and depression.

For both men and women, COPD and depression have a circular, or “bi-directional” relationship. This means that worse COPD symptoms can lead to depression, and that depression can lead to worse COPD symptoms.

This happens for many reasons that have to do with living a healthy lifestyle in general. People who are depressed are more likely to live unhealthy, sedentary lives, and people who live unhealthy, inactive lifestyles are more likely to be depressed.

For instance, studies show a very strong correlation between COPD patients' lung function and their likelihood of being depressed. Worse lung function leads to worse shortness of breath, which in turn leads to higher rates of depression.

As we've discussed already, women with COPD tend to have worse symptoms and worse lung function than men. Thus, it makes sense that women with COPD are also more likely to suffer from depression.

Worse symptoms leads to less physical activity and fewer opportunities to benefit from the protective psychological effects of exercise. This leads to a generally unhealthy and sedentary lifestyle that speeds up psychological, physical, and lung function decline.

Losing strength and endurance also makes it more difficult, or even impossible, to participate in many kinds of normal activities. As a result, many people with severe COPD start to give up on hobbies and other things they enjoy in life, leading to social isolation and depression.

The snowball effect of worse symptoms, less exercise, and worse health also seems to make women more prone to certain COPD complications. It leads to more frequent lung infections, more frequent exacerbations, and puts women even more at risk for other health conditions like osteoporosis.

Occupation

In general, more men than women work jobs that put them at risk for COPD. These jobs include any occupation that exposes workers to dangerous levels of respiratory irritants such as noxious chemicals, smoke, and dust.

Studies show that the jobs that put you most at risk for COPD include coal mining, hard-rock mining, concrete manufacturing, tunnel work, non-mining industrial work, welding, and construction. As it so happens, the vast majority of employees who work in these occupations are men.

Some studies suggest that particular air pollutants, such as chlorine, silica dust, cement dust, and welding fumes pose a greater risk than others. Overall, researchers estimate that occupational exposure causes up to 21 percent of all COPD cases.

Household Tasks

While men tend to dominate many occupations that cause COPD, there are other hazardous jobs and activities that more women than men tend to do. This includes household tasks like cooking and cleaning, which, despite changing gender norms, are still done more often by women than men.

Many studies have shown that both cooking and cleaning expose your lungs to harmful respiratory irritants. Cooking exposes your lungs to aerosolized oils and other toxic chemicals, while common cleaning chemicals emit noxious fumes that can damage your lungs.

This puts men and women who cook and clean frequently for many years at a significantly higher risk of developing COPD. One study, for example,

Pulmonary nodules—or spots on the lung—are the source of a great deal of worry and stress for the thousands of people who are diagnosed with them every year. Despite the fact that pulmonary nodules are relatively common, the majority of people don't really understand what they are or how they work.

Many people's first thought is that pulmonary nodules are cancer—but this is not always true. In reality, most pulmonary nodules are harmless, and only a very small percentage of them turn out to be cancerous.

If you or someone you love has been diagnosed with lung spots, then you might be worried and you might have a lot of questions. In this guide, we hope to answer these questions and give you all the information you need to better understand pulmonary nodules and the level of risk they pose.

In the following sections we'll explain what pulmonary nodules are, what causes them, and what they mean for your health. We'll also take a closer look at the connection between pulmonary nodules and cancer, as well as how pulmonary nodules are related to other lung conditions like COPD.

{{cta('43b79c5e-6bd6-4f02-ac27-2d038d20c146','justifycenter')}}

What Are Pulmonary Nodules?

A pulmonary nodule is simply a small, circular-shaped patch of irregular tissue on the lungs. These patches usually show up after something, like an infection, irritates or damages part of your lung.

Pulmonary nodules are relatively common and often harmless, but they can be cancerous in some cases. You can have just one pulmonary nodule, or you could have several or many nodules on your lungs

Most pulmonary nodules are healed-over wounds—scar tissue, essentially—left behind after a period of inflammation. This inflammation can be caused by a variety of things, including lung infections and certain inflammatory diseases like sarcoidosis and rheumatoid arthritis.

On the other hand, some pulmonary nodules are not created by patches of inflamed tissue, but rather cancerous cells. These cancerous pulmonary nodules are essentially tumors, made up of mutated cells that quickly grow and spread.

Pulmonary nodules are often referred to as “coin lesions,” “spots,” or “shadows” on the lungs, since that's how they appear on scans. On a chest x-ray, for instance, a pulmonary nodule shows up as a small, light-colored or grey-ish spot on the lungs.

Most pulmonary nodules are very small, usually between about ½ inch to a little more than 1 inch wide. They usually don't cause any symptoms, but symptoms are more likely to show up if the nodule grows into a larger lesion (greater than 3cm), known as a mass.

In rare cases, pulmonary nodules can cause respiratory ailments similar to a cold or mild flu. In severe cases, they can cause wheezing, shortness of breath, coughing (or coughing up blood), and respiratory infections.

Are Pulmonary Nodules Serious?

Generally, pulmonary nodules are nothing to worry about. Research shows that they are surprisingly common, asymptomatic, and only carry a “minimal risk” for cancer.

In fact, it is not unusual for someone to have pulmonary nodules for years without even knowing. Since they don't cause any symptoms, most people don't figure out they have spots on their lungs until they show up on an unrelated chest scan.

If you are diagnosed with a pulmonary nodule, don't panic; chances are good that—like most pulmonary nodules—the spot on your lungs is benign. Even cancerous pulmonary nodules tend to be very treatable, since they usually represent an early stage of cancer.

Types of Pulmonary Nodules

There are several different varieties of pulmonary nodules you can get. They are generally differentiated by their cause and whether they are cancerous or benign.

Pulmonary Nodules Caused by Inflammation

A common cause of benign pulmonary nodules is infections and inflammation in the lungs. These can be caused by a variety of things, including:

• Bacterial, fungal, or parasitic infections in the lungs
• Inflammatory diseases like rheumatoid arthritis
• Repeated exposure to lung irritants like smoke

This kind of pulmonary nodule forms as a side-effect of your body's inflammatory response. This response gets triggered whenever your body detects irritation or infection in your lungs, and it helps your immune system fight off the invader.

As part of the inflammatory response, a granuloma, or a small patch of inflamed tissue, can form at the site of irritation or infection. Granulomas are your immune system's way of isolating the infection and preventing it from spreading to surrounding areas.

However, over time calcium deposits can form in the granuloma, leaving behind a permanent spot of calcified tissue. That spot is now a pulmonary nodule that can show up on chest scans long after the original source of irritation is gone.

This type of of pulmonary nodule is usually harmless, asymptomatic, and doesn't grow or change. It is like a scar; just a patch of tissue that's healed over but looks slightly different than it did before.

However, it's difficult to know if inflammation is the cause of a pulmonary nodule without doing further testing. If your doctor has any doubt that it could be cancerous, he will need to monitor the spot to make sure it doesn't grow.

Here is a list of some infections that can cause pulmonary nodules:

• Tuberculosis
• Mycobacterial infections
• Histoplasmosis
• Blastomycosis
• Aspergillosis
• Coccidiobycosis
• Roundworms (ascariasis)
• Hydatid cysts (echinococcus)
• Liver flukes (paragonimous)

Here is a list of some of the common inflammatory conditions that lead to pulmonary nodules:

• Rheumatoid arthritis
• Sarcoidosis
• Granulomatosis with polyangiitis
• Pneumoconioses

Pulmonary Nodules Caused by Cancer

Cancerous pulmonary nodules usually represent a very early form of cancer. They are essentially small, cancerous tumors that, without treatment, would grow larger and spread throughout the lungs.

Luckily, finding a cancerous pulmonary nodule means that you've caught the cancer at it's smallest stage, before it has the chance to grow into a larger tumor, or mass. In fact, the survival rate for most people with a single cancerous nodule is extremely high, up to 70-80 percent.

In rare cases, however, pulmonary nodules can be caused by a metastatic cancer. Metastatic cancers are aggressive forms of cancer that spread between organs in the body, and they can cause cancerous pulmonary nodules if they spread to the lungs.

{{cta('fa8abc2a-1e88-4fa3-82fd-1cb5b9ed43b2','justifycenter')}}

Nodules that are caused by metastatic cancers are usually numerous rather than a single isolated spot. Unlike early-stage pulmonary nodules, nodules caused by metastases are the result of a more serious, later-stage cancer.

Cancerous pulmonary nodules tend to be larger and have more irregular shapes. They are also more likely to appear on a scan as a spot with hazy margins rather than solid, defined edges.

Here is a list of some of the common cancers that cause pulmonary nodules:

• Lymphomas
• Sarcomas
• Carcinoid tumors

Pulmonary Nodules Caused by Benign Tumors

Benign tumor (top) versus malignant tumor (bottom).

Certain types of benign (non-cancerous) lung tumors can show up as pulmonary nodules on scans. These tumors are generally made up of a disorganized mass of cells, but but they do not grow or spread like cancerous tumors do.

Because they are so small, pulmonary nodules caused by benign tumors don't usually cause any symptoms. Most are harmless growths that can be left alone without any further treatment.

However, if a nodule forms in certain places in the lung (e.g. near an airway opening), it can obstruct airflow and cause respiratory symptoms. If this happens, or the tumor causes other symptoms, you may need to have it removed through surgery.

Here is a list of some of the most common types of benign tumors that cause pulmonary nodules:

• Hamartomas (the most common type)
• Blastomas
• Fibromas
• Neurofibromas
• Bronchial adenomas
• Hemangiomas

Other Causes of Pulmonary Nodules

Some types of pulmonary nodules don't fit easily into the any of the categories above. These include nodules caused by blood vessel abnormalities, protein deposits, and other lung conditions.

Here is a list of some of the miscellaneous potential causes of pulmonary nodules:

• Blood vessel abnormalities: e.g. AV malformations
• Amyloidosis: a condition that causes abnormal protein deposits in tissues
• Pulmonary Fibrosis: a serious lung condition resulting from scarred lung tissue
• Atelactasis: the partial collapse of a lung

Who Gets Pulmonary Nodules?

It is not uncommon for someone who develops pulmonary nodules to have an existing respiratory disease such as COPD. However, many people who are diagnosed with pulmonary nodules have had no other respiratory problems up to that point.

People who have a history of smoking are also more likely to have pulmonary nodules than people who have never smoked. Smoking also increases the risk that a pulmonary nodule is cancerous.

However, just about anyone can get a pulmonary nodule, both smokers and non-smokers alike. Basically, if you have lungs, then that means you can get pulmonary nodules.

In fact, so many people have spots on their lungs that they show up on about 50 percent of all chest CT scans and 0.2% percent of chest x-rays. In fact, some estimate that more than half (PDF link) of all adults over the age of 50 have nodules on their lungs.

Is My Pulmonary Nodule Cancerous?

While some pulmonary nodules are cancerous, the vast majority of them are not. (PDF link). In fact, several studies suggest that only about 5 percent of pulmonary nodules found via CT scan turn out to be cancer; the other 95% of the time, they are benign.

However, certain factors can increase the likelihood that your pulmonary nodule is cancerous. For instance, the risk of cancer is higher if the nodule is large, if you are over the age of 40, or you have a history of smoking.

Nodules found via chest x-ray also have a higher risk of being cancerous, simply because only larger pulmonary nodules show up on x-ray scans. X-ray technology is not as sensitive as a CT scan, meaning smaller pulmonary nodules—which are more likely to be harmless—are much more likely to show up on a CT scan than a chest x-ray image.

Most of the time when someone is diagnosed with a pulmonary nodule, doctors recommend simple monitoring to see if the spot grows. That means taking additional scans of the lungs—usually about six months apart—and comparing the images to look for any changes.

If the nodule doesn't get larger over time, then it's likely that it is benign. In fact, there is usually no need to continue doing scans if the images show that the spot hasn't grown for two full years.

However, if the nodule does grow, there is a higher chance that it could be cancerous. But in order to know for sure, you will need to get the spot analyzed through a biopsy, which we'll discuss this more in sections below.

Fortunately, cancerous pulmonary nodules are most often a very early, very treatable stage of lung cancer. It is much better to catch lung cancer at this stage rather than later, when the cancer has grown, spread, or begun causing symptoms.

Factors that increase the risk that a pulmonary nodule is cancerous:

• The pulmonary nodule is large (e.g. more than 30 millimeters across)
• The pulmonary nodule grows over time (as tracked via chest scans)
• The pulmonary nodule's borders are irregular, spiky, or blurry (instead of rounded and well-defined)
• The nodule is not calcified (calcified nodules are usually benign)
• The nodule is located in an upper lobe of the lung
• You have a history of smoking
• You are over the age of 40
• You have COPD
• Your have a family history of cancer (especially lung cancer)
• You have been repeatedly exposed to substances that can cause lung cancer, especially through your occupation (e.g. diesel fumes, chemical solvents, second-hand smoke, etc.)

Pulmonary Nodules and COPD

Many people with COPD also have pulmonary nodules. However, the two conditions are not directly related; COPD does not directly cause pulmonary nodules and pulmonary nodules do not cause COPD.

Instead, it is likely a combination of shared risk factors that causes pulmonary nodules to be more common in people with COPD. Both conditions are the result of damage to the lungs, which can occur for a variety of health and lifestyle reasons.

Smoking, for instance, is perhaps the most significant risk factor that both COPD and pulmonary nodules share. Both conditions can be caused or worsened by the repeated inflammation that occurs when you smoke for many years.

Put simply, the same things that cause lung damage that leads to COPD can also cause lung damage that leads to pulmonary nodules. This is the most likely reason that pulmonary nodules are more common in people with COPD.

The fact that COPD is, in part, an inflammatory condition, could also be a factor. Lungs affected by COPD are much more prone to inflammation than healthy lungs, which creates more opportunities for granulomas, cancer, and pulmonary nodules to form.

Lung infections are another cause of pulmonary nodules that are also linked to COPD. It is common for people with COPD to experience frequent respiratory infections, which can in turn raise their risk for developing nodules on their lungs.

Unfortunately, lung nodules in people with COPD also carry a higher risk of being cancerous. That's because COPD is itself an independent risk factor for lung cancer, even when you ignore the common risk factor of smoking.

How Pulmonary Nodules are Treated

Most people first find out they have pulmonary nodules when they get a CT scan. Often, the scan is being done for an unrelated reason when a doctor notices a lung spot (or spots) on the image.

After discovering the nodule, your doctor will likely ask you some questions about your health and lifestyle. This allows him to look for any factors that could indicate a higher risk of lung cancer.

Your doctor will use this information as well as the characteristics of the spots on the scan to estimate the risk that the nodule is cancerous. Then your doctor will likely decide to do one of three things: ignore the nodule, do a biopsy, or monitor the nodule to see if it grows.

Often, the next step is simply to keep an eye on the spot to see if anything changes. However, your doctor may want to test the spot for cancer right away if it shows cancerous characteristics, if you have symptoms, or your have other significant risk factors for lung cancer.

Monitoring the Spot

After getting diagnosed with a pulmonary nodule, your doctor may choose to take a “wait and see” approach. That requires taking more CT scans in the future—often about 6 months apart—to monitor the spot over time.

Your doctor will compare the new scans with previous images of your lungs to look for signs of cancer. If the nodule grows or shows cancer-like changes, then you will need further testing to figure out if it's cancerous or benign.

Most of the time, however, pulmonary nodules do not grow between scans and turn out to be benign. If it shrinks or shows no change over the span of two years, then it means the spot is most likely cancer-free and there's no need to monitor it anymore.

Testing Pulmonary Nodules for Cancer

If your doctor suspects that your pulmonary nodule is cancerous, then he will order a biopsy of the spot. That means taking a small sample of the tissue to analyze it more thoroughly for signs of cancer.

There are three main ways to do this: by inserting a needle through the chest wall, by performing chest surgery, and by using a bronchoscope. A bronchoscope is the least invasive method, and it works by inserting a scope down the throat and into the airways to take the sample directly in the lungs.

Once they get the tissue sample from the lung nodule, an expert will then take a closer look at the tissue to look for signs of cancer. Even if the nodule appears to be benign, your doctor might decide to monitor it for awhile just to be sure. If it is cancerous, then your doctor will refer you to an oncologist who will put together a full cancer treatment plan.

Treatment for Benign Pulmonary Nodules

If your doctor confirms that your pulmonary nodule is benign, then you probably won't need any further treatment. However, you might need medication if your nodule is the result of a current infection.

If an inflammatory disease is the cause of your pulmonary nodule, then you may need treatment to get the underlying condition under control. For example, your doctor may prescribe anti-inflammatory medications like corticosteroids to reduce inflammation in your lungs.

What You Can Do: Don't Panic

If you or someone you love has just been diagnosed with pulmonary nodules, you should do your best not worry. Remember that most lung spots are not cancerous and won't do any harm.

Unfortunately, evaluating pulmonary nodules is often a waiting game. Your doctor will likely need time to monitor the spot and look for growth or other changes.

This “wait and see” approach can be frustrating and scary when you're anxious to know the results. But if you can manage not to panic, the wait will be much easier to bear.

Of course, it's only natural to worry after you get diagnosed with a pulmonary nodule. It can help to talk to your doctor, who can help you understand the condition and tell you more about your personal risk.

Learning more about pulmonary nodules can also help you feel less worried. The knowledge can eliminate the fear that comes from facing the unknown and help you feel more secure.

After reading through this guide, you should know much more about pulmonary nodules, how they get diagnosed, and how they're connected to COPD and other health conditions. This should help you understand your diagnosis and what having a spot on your lungs actually means.

If you’re a fiscally responsible person, you’ve probably trained yourself over the course of your life to avoid unnecessary financial spending. Maybe you limit the number of times you eat out per week, take public transportation, or avoid buying that expensive latte before work. This is a great quality to have because it means you’ll be able to save up more money for things that matter like paying off the mortgage or saving for your children’s or grandchildren’s education.

However, being frugal also implies that you understand the importance of a good investment. A wise financial investment will provide you with long-term benefits to your health and happiness, and at times, they can even provide you with financial benefits as well. For example, making conservative and carefully placed investments in the stock market can help you grow your wealth and improve your financial well-being over time.

One thing you’ll hear financial experts talk about a lot is seeing yourself as an “asset.” In other words, when you invest in yourself — whether it be through education, health, or some other method — you’re likely to reap the benefits in the future. Here at LPT Medical, we see a lot of COPD patients who are wary about investing in a portable oxygen concentrator because they’re unsure whether it’s a wise investment or not. If this sounds like you, read on because we’re going to show you why POCs are always a great financial investment and that there are no benefits to waiting.   

{{cta('fa8abc2a-1e88-4fa3-82fd-1cb5b9ed43b2','justifycenter')}}   

They Offer Many Long-Term Benefits

Sometimes, the biggest roadblock for someone who’s interested in the prospect of buying a portable oxygen concentrator is their perspective. They may look at oxygen tanks and POCs side-by-side and choose tanks simply because they have a lower-upfront cost. While this may be a great way to look at other products, it’s the wrong way to go about choosing an oxygen therapy device. 

First and foremost, this perspective does not take into account the way oxygen tanks are refilled. Sure, you can purchase an oxygen tank for a couple of hundred bucks or even rent one, but the cost to maintain and refill them is vastly more than what portable oxygen concentrators cost. If you want to refill your oxygen tanks at home, you’re going to need to own a home fill oxygen station. These machines take up a lot of space and they cost anywhere between $2,000 and $3,000. That’s already a steeper price point than most portable oxygen concentrators.

If you decide to go an alternative route and pay someone else to refill your oxygen tanks, you’re going to be spending upwards of $8 per fill. This may not sound like a lot, but when you’re paying it daily, it racks up pretty quickly. Since this is an incredibly inefficient way of paying for oxygen therapy, you’d likely want to invest in more oxygen tanks as backup units. That way you wouldn’t have to go out of your way constantly to get them refilled. On top of all of this, you may find it difficult to even find a place to refill your tanks in the first place.

Alternatively, purchasing a portable oxygen concentrator means never having to pay to refill your oxygen ever again. POCs run entirely off electricity so all you need is a functioning battery and you will have an infinite supply of oxygen wherever you go. What’s more, the need for repairs and maintenance on portable oxygen machines is minimal, so you can rest assured that your investment will be good for years to come. 

Your Freedom Can’t Wait

America is all about freedom, but there’s a reason for this — it’s one of the most fundamental human rights. Think about it, if you had someone else controlling you your whole life, chances are, this would not be a life worth living. The same concept applies when you’re talking about chronic debilitating diseases like COPD or cystic fibrosis. Why would you choose to be restricted by your condition when you could be enjoying the freedom and independence that comes with having a portable oxygen concentrator?

It may be tempting to delay getting a portable oxygen concentrator just for the chance of finding a great deal or maybe you’re even looking for a used or refurbished portable oxygen concentrator. Although we do offer refurbished and used portable oxygen concentrators, we highly recommend purchasing a new one. We are always offering great deals on our latest and greatest oxygen machines including the Inogen One G5, Caire FreeStyle Comfort, and much more. We are even offering a free THRIVE eLearning course with the purchase of a new oxygen machine.

The bottom line is that freedom is always worth fighting for. Pulse flow portable oxygen concentrators are the lightest and smallest oxygen delivery devices on the planet meaning you will be able to go more places and do more things than you ever thought possible. With the long-lasting batteries, you’ll be able to stay out and about for longer without having to worry about running home to recharge or finding an oxygen supply store. Lastly, they’re extremely easy to use, so adjusting your oxygen output settings or swapping out batteries can be done in a matter of seconds on the fly. 

Your Health is Paramount

In the grand scheme of things, your health is equally as important or even more important than your freedom and independence. In fact, without first ensuring your basic health needs are met, it’s unlikely you’ll be able to get outside and explore the world on your own terms. As a COPD patient, oxygen therapy is crucial for your overall health. It helps to reduce common symptoms such as breathlessness, chest pain, coughing, and wheezing. And despite what many people will have you believe, oxygen concentrators are just as effective at delivering high-grade medical oxygen as oxygen tanks are.

Many modern portable oxygen concentrators come equipped with pulse dose technology. Rather than putting out a constant stream of oxygen like an oxygen tank or a continuous flow oxygen concentrator, this system closely monitors your breathing and only puts out oxygen when you inhale. It also precisely times the oxygen dosage to ensure that nothing is wasted. What this means is that you’ll be receiving the same amount of oxygen as you would with other oxygen machines but your POC won’t be wasting any oxygen. This allows manufacturers to make their devices smaller and lighter than ever before.

Ultimately, purchasing a portable oxygen concentrator is not something you should wait on when your health is at risk. Studies have shown that long-term oxygen use for patients with low respiratory function experience a higher survival rate than patients who do not. They also experience higher hospitalization rates than oxygen users due to exacerbations and other health issues. So, not only is your health at risk but putting off oxygen therapy could pose serious financial risks as well.  

There Are Few Effective Alternatives

If you’re still skeptical about portable oxygen concentrators you should take some time to consider the alternatives. Aside from pulse flow portable oxygen concentrators, there are continuous flow portable oxygen concentrators, stationary oxygen concentrators, oxygen tanks, liquid oxygen tanks, and portable oxygen cylinders. Each of these has its own pros and cons, but at the end of the day, pulse flow portable oxygen concentrators will be the best investment for the largest number of oxygen users.

Oxygen tanks have been in use for quite some time. The 1950s largely paved the way for in-home oxygen use because we saw inventions such as the nasal cannula which were much safer and effective than other delivery methods used in hospitals. By the 1960s, compressed oxygen tanks could be delivered to patient’s homes. At the time, this was a revolutionary practice because it meant keeping bedridden patients out of the hospital.

In the 1970s, compressed oxygen tanks were largely pushed out of homes in favor of home oxygen concentrators (stationary oxygen concentrators). Instead of holding oxygen, the new concentrators would draw in ambient air, remove nitrogen, argon, and other gases, then put out medical-grade oxygen. Not only were concentrators safer than compressed oxygen tanks but they didn’t need to be refilled. Despite concentrators largely replacing oxygen tanks, oxygen manufacturers continued to innovate tanks by offering patients portable oxygen cylinders and liquid oxygen tanks.

Portable oxygen cylinders are essentially smaller versions of home oxygen tanks. However, because oxygen can only be compressed so much before it becomes unsafe, liquid oxygen tanks were introduced. These new units could hold more oxygen because liquid takes up less space than compressed air. The one downside to this is that oxygen needs to be stored at -297 degrees Fahrenheit in order to remain in its liquid form. They were also notably safer than compressed oxygen because they’re stored at low pressure.

In the 1990s and early 2000s, we saw a number of advancements in battery technology, primarily with lithium-ion batteries. There was a huge push to make these batteries lighter and last longer in order to power devices like cell phones and laptops. Oxygen manufacturers like Inogen took note of this and decided to invest in the creation of a new type of concentrator, similar to those used in the 1970s, but it could be transported anywhere. 

Today, there are two types of portable oxygen concentrators on the market: continuous flow portable oxygen concentrators and pulse flow portable oxygen concentrators. Continuous flow units offer great oxygen output and most even let you choose between continuous flow and pulse flow oxygen delivery despite what their name would suggest. Unfortunately, these oxygen concentrators tend to be bulky with the lightest one weighing in at 10 pounds. They also have poor battery life, so you should expect to stay close to home.

Finally, we come to pulse flow portable oxygen concentrators. These concentrators offer enough oxygen output for the vast majority of oxygen patients, but they don’t have a lot of the downsides that come with all the aforementioned oxygen devices. They’re extremely lightweight, ranging from 1.75 pounds to just over 6 pounds, they have long-lasting batteries, and they’re light and small enough to be taken just about anywhere. They’re also approved by the Federal Aviation Administration (FAA) meaning you’ll be able to travel across the world with ease. 

At this point in time, there isn’t much of a debate as to which oxygen delivery device is best. While there are a few situations where the use of continuous flow oxygen concentrators is advised, pulse flow POCs are almost always the best way to go.

{{cta('fa8abc2a-1e88-4fa3-82fd-1cb5b9ed43b2','justifycenter')}}

You Have a Wide Variety of Options

Just because pulse flow oxygen concentrators are definitively the best oxygen delivery method on the market doesn’t mean you won’t have many options available to you. Within the past decade, we’ve seen the release of a host of advanced POCs produced by a variety of reputable and well-established manufacturing companies. Let’s take a look at just a few of the great options out there you can choose from.

The Inogen One G5

The Inogen One G5 was released in the summer of 2019 and it’s currently considered one of the best POCs out there. One of the standout features of this portable oxygen concentrator is that it offers a flow setting of 6 which is higher than any other pulse flow unit. In terms of total oxygen output, this is the equivalent of 1,260 ml/min of medical-grade oxygen. But the Inogen G5 doesn’t skimp in other areas either. It offers astounding battery life up to 13 hours on one charge, a lightweight design, and additional features like the Inogen Connect which allows you to track your G5 battery life through your phone or tablet.

COPD is a chronic respiratory disease that impairs your breathing capabilities, and due to the deprivation of oxygen, the disease will affect other aspects of your life beyond the function of your lungs. If your body cannot process the oxygen in the air enough for your body, parts of your brain will, in some cases, be affected by this.

This is not something that should frighten you, however, many people will chalk up forgetfulness to be associated with older age, or being too busy, or having too much on their mind. Every time you think to yourself, “Where did I put that” or “ What was I about to do?” you should also think about becoming more aware of what this means for you.

Especially if you have COPD, mindfulness and attention to details can go a long way in creating a more habitable living space both physically but also inside your mind.

{{cta('fa8abc2a-1e88-4fa3-82fd-1cb5b9ed43b2','justifycenter')}}

Similarly to COPD, Mild Cognitive Impairment (MCI) has no cure, however, there are ways you can work to prevent it from affecting you severely.

Cognition is associated with learning, memory, and thinking. So, cognition is about your language, memory, how you learn, reasoning, recognizing, and categorizing. It is how we see our environment and how we adapt to it. All of which will progress, change, and be affecting by time and your age.

However, if you have COPD, age may not be the main factor in your cognitive decline. Due to the symptoms associated with COPD there is a risk that you will experience MCI and other memory issues.

In general, mild cognitive impairment (MCI) is a condition that causes minor problems with memory, focus, problem-solving, and attention. It happens to many people as they age, but respiratory diseases like COPD can both trigger and accelerate the condition.

If you experience forgetfulness or worry that your mind is not as “sharp” as it used to be, you are actually experiencing the symptoms of mild cognitive impairment. However, MCI is slightly worse than the normal changes to memory and cognition you'd expect to see with age alone.

Mild cognitive impairment happens when your brain's cognitive functions are slightly lower than they should be. It can result from both temporary problems like oxygen deprivation and permanent changes that occur when you experience structural damage to your brain.

The National Center for Biotechnology Information advances science and health journal suggests that mild cognitive impairment is very common, affecting about 10-20 percent of people over the age of 65 and about 36 percent of people with COPD.

Fortunately, mild cognitive impairment is a treatable, and sometimes even reversible, condition that can improve with diet, exercise, and other lifestyle changes.

How to improve Mild Cognitive Impairment

Exercise:

You need to exercise every day with COPD, we have talked about exercise in almost every blog post about COPD since the beginning of time. And while it does help to strengthen your lungs, exercise does more than that.

Many studies including work from the JAMA Network, suggests exercise can provide better blood flow to your brain releasing molecules that could repair your brain and prevent it from getting worse. By exercising, your body will release serotonin and endorphins that will help make you want to exercise more frequently, which is a very healthy cycle!

Diet:

The National Center for Biotechnology Information published a study that concluded there are significant associations with the risk of MCI and a person’s diet. This means that a moderate intake of cooked white rice and an adequate intake of whole grains, fruits, milk, and dairy products were associated with reduced risks of MCI among adults aged over 50 years.

Having a diet rich in vitamins and minerals keeps our brain happy and allows you to be more active.

Mindfulness and Meditation:

Medication and other mindfulness exercises can help calm your mind and allow you the space you need to keep things in perspective. Findings in a De Gruyter publishcation study recommended that there be future studies on meditation-based treatment for MCI and stress management because of how influential the practice was when used to treat these cognitive impairments, and more information should be processed to understand this phenomenon further.

Games and puzzles:

{{cta('43b79c5e-6bd6-4f02-ac27-2d038d20c146','justifycenter')}}

Engaging in mentally stimulating games and puzzles can make a huge difference in the prevention and treatment of MCI. Just like exercise for your muscles so they get stronger, it is important to work out the neurons in your brain. By doing mind games and puzzles, your brain will be able to make connections and you can work to keep those connections and neurons strong and firing.

COPD, MCI, and oxygen therapy

So the connection between COPD and MCI is very strong, and studies showed that patients with COPD had an increased risk for MCI by about 83 percent. These patients who had COPD for more than five years had a greatest risk for MCI.

The reason behind the connection is still not completely understood, and research suggests that COPD is associated with risk of MCI. The next step for researchers is to understand the exact mechanisms by which COPD increases the risk of MCI.

Until then, oxygen therapy, either by utilizing oxygen tanks or portable oxygen concentrators, can be beneficial for improving memory and other symptoms associated with COPD induced MCI.

If your blood oxygen saturation is below 90 percent, that means you're not getting enough oxygen to meet your body's needs and you likely need supplemental oxygen therapy. If you already use supplemental oxygen, experiencing mild cognitive impairment could be a sign that your oxygen prescription needs to change and you should discuss this with your doctor as soon as possible.

In this case, your doctor may decide to increase your oxygen dosage or instruct you to use supplemental oxygen more often. You might also need to start using oxygen while you sleep, since nighttime oxygen deprivation is a common cause of MCI.

Understanding COPD and MCI

If you have been diagnosed with COPD, it is crucial that you take daily notes of your symptoms and which aspects of your life are being affected. By understanding what is happening in your body and mind, you and your doctor, will be able to set up a treatment plan that is special for you whether that means beginning on oxygen therapy, or starting a pulmonary rehab course.

If you begin to realize that your memory or aspects of your cognition are worsening, this could be attributed to your COPD, and there are ways that you can begin to reverse or slow down mild cognitive impairment from advancing into a more severe state.

If you focus on treatments that will help your MCI, you are also working towards a healthier lifestyle with COPD. These treatments over-lap, like eating brain healthy foods, exercising regularly, meditating, and doing puzzles and playing mind games, while also being prudent to use supplemental oxygen therapy will all contribute to slowing down the progression of both COPD and MCI.
