Chronic Obstructive Pulmonary Disease
Chronic Obstructive Pulmonary Disease Chronic Obstructive Pulmonary Disease (COPD) is a progressive lung disease that makes it intensely difficult to breathe. This disease affects millions of Americans and affects tens of millions of people around the world (Jones, 2001). With COPD, the tissue where oxygen is exchanged is destroyed due to the thickened and inflamed airways in the lungs. This decreases the flow of air coming in and out of the lungs. When this occurs, body tissues receive less oxygen making it harder to get rid of the waste gas, carbon dioxide. As the disease progresses, it becomes increasingly difficult to remain active due to shortness of breath. Chronic Obstructive Pulmonary Disease has no cure, however, it is often preventable …show more content…

Some common causes of COPD include smoking, genetics, bacteria and viruses, and other environmental factors. Cigarette smoking is the leading environmental factor associated with COPD and smokers are at greater risk for developing this disease as opposed to non-smokers (Clancy & Turner, 2013). According to Cope (2014), cigarette smoking triggers inflammation in the central and peripheral airways and lung tissue, all of which disrupt the lungs defense mechanisms, resulting in an accumulation of mucus that harbors bacteria which ultimately leads to infection. Genetic risk factors, such as Alpha-1 antitrypsin deficiency (AATD), has been associated with the emphysema type of COPD (Chronic Obstructive Pulmonary Disease, n.d.). The protein that helps protect the lungs against damage from toxins is Alpha-1 antitrypsin (AAT). People who lack this protective enzyme experience damage to the alveoli and the airways leading to them (Chronic Obstructive Pulmonary Disease, …show more content…

The Global Initiative for Chronic Obstructive Lung Disease (GOLD) created a system that categorizes the severity of COPD into stages. The GOLD system uses the forced expiratory volume (FEV1), the maximum amount of air you can forcefully blow out of your lungs in one second, and breaks that down into four stages. In stage one, airflow limitations are mild and most individuals do not know they have COPD. This is due to the fact that symptoms may be very mild and may be attributed to more common explanations, such as a cold. In stage two, airflow limitations begin to exacerbate and symptoms become more apparent. Stage three of COPD is marked by an increase in the severity of coughing and the worsening of symptoms. Airway passages are restricted and/or obstructed. Lastly, in stage four of COPD, respiratory failure may lead to heart complications and an impaired quality of

    COPD stands for Chronic Obstructive Pulmonary Disease. It is typically caused by inhaled irritants such as tobacco smoke. It is a chronic inflammation of the airways, lung tissue, and pulmonary blood vessels. It limits air flow and is irreversible. The inflammation causes excess mucus production. This results in chronic cough, dyspnea, and wheezing. The inflammation response is caused by a grouping of cells in the airways from neutrophils, T-lmyphocytes, and other inflammatory cells that trigger…

    Chronic obstructive pulmonary disease (COPD) is one of the most common lung diseases and makes it very difficult to breathe. There are two main forms of COPD: Chronic bronchitis, which involves a long-term cough with mucus, and Emphysema, which involves destruction of the lungs over time. Most people with COPD have a combination of both conditions. Smoking is the leading cause of COPD. The more a person smokes, the more likely that person will develop COPD. However, some people may smoke for years and will never get COPD. In rare cases, nonsmokers who lack a protein called alpha-1 antitrypsin can develop COPD at an early age. Other risk factors that put a person at risk for COPD are: exposure to certain gases or fumes in the workplace, exposure to heavy amounts of secondhand smoke and pollution, and frequent use of cooking fire without proper ventilation.…

    Chronic obstructive pulmonary disease (COPD) refers to a group of lung diseases that block airflow and make breathing difficult. The two main factors that cause COPD are emphysema and chronic bronchitis. “In emphysema, the walls between many of the air sacs are damaged. As a result, the air sacs lose their shape and become floppy. This damage also can destroy the walls of the air sacs, leading to fewer and larger air sacs instead of many tiny ones. If this happens, the amount of gas exchange in the lungs is reduced. In chronic bronchitis, the lining of the airways is constantly irritated and inflamed. This causes the lining to thicken. Lots of thick mucus forms in the airways, making it hard to breathe. (What is chronic obstructive pulmonary disease?)”. Patients with COPD are diagnosed by a physical examination, chest radiograph, pulmonary function test, blood gas analysis CT scan and arterial blood gases (Huether and McCance, Pg. 683 and 684). Treatment of COPD includes the use of inhaled anticholinergic, beta agonist, and corticosteroids. Pulmonary therapy, improved nutrition and breathing techniques can improve symptoms. If those treatments fail, then oxygen therapy must be started to ensure the patient is not hypoxic.…

    Chronic Obstructive Pulmonary Diseases (COPD) is a chronic inflammatory lung disease with no cure. COPD causes the lung to deteriorate which prevents breathing. People with this disease have cough, shortness of breath, damaged airways, chest infections and pain. These symptoms impair patients’ mobility and contribute to be housebound. Patients with COPD tolerate the burden of this disease for many years (6 years)6.…

    As inflammation continues, the airways constrict, becoming excessively narrow and swollen. This leads to excess mucus production and poorly functioning cilia, a combination that makes airway clearance especially difficult. When people with COPD can't clear their secretions, they develop the hallmark symptoms of COPD, including a chronic, productive cough, wheezing and dyspnea. Finally, the build-up of mucus attracts a host of bacteria that thrive and multiply in the warm, moist environment of the airway and lungs. The end result is further inflammation, the formation of diverticula (pouch-like sacs) in the bronchial tree, and bacterial lung infection, a common cause of COPD exacerbation.…

    “Prolonged cold weakens out resistance to infection” is a statement that’s true whether or not you’re in a weakened state of health. For those that are, for instance, people with chronic obstructive pulmonary disease (COPD), the effects of cold can be much more severe and potentially more likely to be permanently damaging. As is explained by Liesl Osmond, regarding a study conducted regarding temperature and sufferers of COPD, “This is the first time a direct relationship has been found between the number of hours a house is warm and respiratory health status – in this case that of patients with COPD, and it would seem that this relationship is most marked for smokers.” While it should come as no surprise that smoking will effect your respiratory health, it is interesting to note that the smokers that were part of the study who suffered from COPD had better respiratory health when exposed to warmer temperatures than those who lived in buildings with below-ideal temperatures.…

    Chronic obstructive pulmonary disease (COPD) is a progressive lung disease that gradually affects a personal ability to breath. COPD is an ailment that destroys the tissues of the lungs where oxygen is exchanged which results in coughing, that produces excessive amounts of mucus, and shortness of breath caused by inflammation and stiffening of the airways. In this condition, there is an obstruction in the lungs which causes less air oxygen to reach the necessary tissues which make it more difficult to dispose of carbon dioxide. Through the progression of the disease it becomes more challenging to remain active due to shortness of breath.…

    Chronic Obstructive Pulmonary Disease, is a Chronic and progressive illness that affects a person’s ability to breath. The affects to breathing occur due to obstructive airways caused by production of mucous from continuous inflammation and by constrictive airways caused by the narrowing of the bronchial tubes from spasms, scar tissue, reactive airways, infections of the lung, and the continuous response to irritating substances within the environment. Pollution, smoking, and other irritating substances cause the negative and damaging cascade of events that follow.…
