According to the Centers for Disease Control, Chronic Obstructive Pulmonary Disease (COPD) is the fourth leading cause of death among Americans. As its name implies, this is an ongoing condition that obstructs airflow through the lungs, and there is no cure. The good news is that oftentimes it can be prevented through lifestyle changes, and symptoms can be alleviated through inhalers, nebulizers and oxygen therapy.
Under the heading COPD fall asthma, chronic bronchitis and emphysema. Asthma is the one condition that isn’t preventable and typically has a genetic component. Interestingly, the National Institutes of Health have a theory that modern advances in hygiene and reduced exposure to infections have made children more sensitized and less resistant to allergens and other particulates that can trigger an asthma attack. Of course, this doesn’t mean we should stop immunizing our children and quit cleaning the house, but it is an interesting trade-off when it comes to childhood illness.
Chronic bronchitis and emphysema are preventable conditions. Chronic bronchitis is a persistent inflammation of the lungs with a productive cough lasting for at least three months over a two-year period. In a healthy lung, little hair-like cells called cilia keep particles moving through the airway; with increased and constant mucus, these cells wear away and are replaced by goblet cells that seem to attract mucus and do nothing to clear it out. Of course, the warm, moist environment of a compromised lung is the ideal breeding ground for bacteria and acute lung infections. When the lungs are constantly inflamed over time, the airway can constrict permanently; at this point it becomes COPD.
One of the most telling symptoms of emphysema is “smoker’s cough,” but this condition is insidious and can be brewing for many years of poor lifestyle choices before you sound like a freight train. Shortness of breath is the first sign; you may start avoiding physical activity or exercise that leaves you out of breath. Rapid heartbeat is another symptom, indicating that your heart is working harder to accommodate the lungs’ insufficiency. In its end stage, emphysema shows up as bluish and/or clubbed fingers due to lack of oxygenated blood flow, pursed-lip rapid breathing and a barrel chest since the rib cage must expand to accommodate lung expansion.
As stated above, there is no cure for COPD, but you can reduce its severity by:
- Not smoking. Your doctor can explain the wide range of smoking cessation programs out there, from prescription medication to over-the-counter nicotine patches. This is the best prevention against COPD. In fact, according to Dr. Norman Edelman of the American Lung Association, “the lungs will get better in weeks to months. Breathing will get better. Exercise capacity will get better. Paradoxically, people find that they cough a little more right after they stop smoking, but that's natural. That's the lungs cleaning themselves out.”
- Breathing exercises. Your doctor may set you up with a respiratory therapist who can instruct you on breathing exercises to strengthen your lungs and diaphragm muscles. Your lung function can be determined by an incentive spirometer that measures the volume of air in your lungs and gives you a goal to shoot with an adjustable indicator. Pursed lip breathing and breathing from the diaphragm are two ways COPD patients can get more air with less effort.
- Medications. Again, your doctor can recommend treatment options, including fast-acting inhalers for exercise or strenuous activities, and long-acting inhalers for daily use. This won’t cure the condition, but they will make it easier to deal with. Nebulizers are also used for acute episodes: these are portable machines that deliver an aerosolized mist of medication into the airway.
- Oxygen therapy. As the disease progresses, patients require supplemental oxygen to maintain their activity level and sleep better at night. Oxygen therapy can be delivered through portable units or set up in the home with a concentrator device. Some patients will also experience sleep apnea, where they stop breathing episodically. In this case, they will need a CPAP (Continuous Positive Airway Pressure) unit that offers restful sleep, as opposed to waking up after each apnea episode.
