Causes Of Chronic Obstructive Pulmonary Disease
Chronic Obstructive Pulmonary Disease is used to describe several conditions which include chronic bronchitis. This condition causes the airways to become inflamed and the air sacs to become narrow and this then makes it harder for the patient to breathe in and out.
COPD is mainly caused by smoking which irritates the lungs and causes them to become inflamed which can lead to scarring. When the inflammation builds up usually over some years, the walls of the airways thicken and more mucus is produced causing the patient to cough and produce phlegm. The persistent cough and phlegm is a main symptom of COPD. Another symptom is increased breathlessness even when carrying out daily activities such as climbing steps. COPD could also result in frequent

    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.

    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.…

    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.…
