Chronic Obstructive Pulmonary Disease

The main cause of chronic bronchitis is smoking due to the lungs’ airways being affected by mucus. Other irritants to the lungs include dust, chemicals, pollen, outdoor pollutants, and more. Over time, these can become factors for the development of chronic bronchitis. Emphysema, another part of the triad, is also progressive. The Mayo Clinic (2005) explains that emphysema causes a loss of elasticity in the walls of the small air sacs in (the) lungs. Eventually, the walls stretch and break, creating larger, less efficient air sacs that are not able to handle the normal exchange of oxygen and carbon dioxide. Emphysema is usually not detected in its earlier phases and approximately three million people are diagnosed with emphysema after it has progressed and the effects are irreversible. Like chronic bronchitis, the main cause of emphysema is cigarette smoking. Low protein deficiencies and genetic factors may play a small role also. Asthma is also part of the COPD, as stated earlier. Asthma is a chronic disease that affects your airways, which are the tubes that carry air in and out of your lungs. The airways become highly sensitive when inflamed and react strongly to irritants and allergens. They react by constricting and becoming smaller; therefore, causing wheezing, air restriction, tightness of the chest, and coughing. COPD leads to a decrease in airflow when an individual exhales. The obstruction of airflow causes the body’s system to struggle in order to breathe and this obstruction causes oxygen to be trapped in the lungs. ...

Chronic airway diseases
Asthma and chronic obstructive pulmonary disease (COPD) form the majority of lung diseases typified by airflow limitation. Asthma is a distinct clinical entity, differentiated from COPD on the basis of onset at an early age, largely reversible airway obstruction and an associated history of allergy (Celli & MacNee 2004). The term COPD has traditionally included two components: chronic bronchitis and emphysema. Chronic bronchitis is epidemiologically defined as presence of cough and mucous production in at least 3 consecutive months for at least 2 consecutive years (Global Initiative for...

National Heart Lung and Blood Institute (2010) reported that COPD is irreversible with no known treatment to date making it as the leading cause of disability and ranked as the third contributing factor of mortality in the United States. National Heart Lung and Blood Institute added that emphysema and chronic bronchitis are the two most common conditions referred to by physicians as COPD since the two characteristically coexists.

Chronic Obstructive Pulmonary Disease
The paper work “Chronic Obstructive Pulmonary Disease” investigates the main issues concerning lung diseases. Basically described, chronic obstructive pulmonary disease, or COPD refers to a lung disease which normally makes breathing difficult. According to Currie (2009), COPD results from a combination of two diseases, chronic bronchitis and emphysema; hence, in essence, COPD does not refer to a single disease but rather an umbrella term describing chronic lung diseases. Chronic bronchitis would normally involve the inflammation of bronchial tubes, being the airways that transport air to...

Chronic Obstructive Pulmonary Disease
The cough has sputum and the patient constantly has mucus (Wright and Churg, n.d). Emphysema, which is caused by deterioration of the air sacs in the lungs, is the other form of COPD, as the patient ages the holes in the air sacs get bigger causing difficulty in breathing (Wright and Churg, n.d). For the case study, we will look at Stella Bernhardt a sixty two year old who comes from a family with a smoking history and cancer history as her mother and 2 aunts died from lung cancer. She had been smoking one pack per day for the past forty-six years and her attempts to quit had not been...

Chronic obstructive pulmonary disease and asthma
The lung parenchyma destruction is the irreversible characteristic of COPD, which is not depicted in asthma; therefore, corticosteroids fail to alter the progression of Chronic Obstructive Pulmonary Disease (Barnes, 2000). A deep insight is given in the study conducted to establish a co-relation between these two closely related diseases.
