describe the chronic obstructive pulmonary disease

Expert Solution

Chronic obstructive pulmonary disease or COPD is apreventable and treatable slowly progressive respiratory disease of airflow obstruction involvin the airway, pulmonary parenchyma or both. The airflow limitation or obstruction in COPD is not fully reversible. Most of the COPD patients presented with overlapping signs and symptoms of emphysema and chronic bronchitis. So COPD may include diseases that cause airflow obstruction or any combination of those disorders.

Risk factors of COPD include passsive smoking, exposure to tobacco, increased age, occupational exposure, air pollution, genetic abnormalities etc.

Pathophysiology of COPD is by any of the risk factor the inflammatiory response occur throughout the proximal and peripheral airways, lung parenchyma etc. Inflammation causes thicknening of the airway wall and overall narrowing. It leads to decreased air flow through the trachea and bronchi.

Treatment for COPD include bronchodilators which relieve the bronchospasm, corticosteroids to relieve the inflammation, oxygen therapy to maintain normal oxygen saturation. Also risk reduction techniques such as avoid smoking, regular check up etc are used to prevent the COPD.

Surgical management such as bullectomy, lung transplantation are also used in severe cases.

Discuss in detail chronic obstructive pulmonary disease (COPD). Compare and contrast chronic bronchitis and emphysema (include manifestations, etiologies, diagnosis and treatment). Describe the pathophysiology of COPD (include heart, kidney, respiratory muscle compensations, pH discussion, ventilation/perfusion mismatching) What is the significance of the central chemoreceptors in the brainstem in relation to the body's response to these conditions. Why may it be dangerous to give patients high flow oxygen?

A 50 year old man with a history of chronic obstructive pulmonary disease (COPD) came to the emergency room because of a fever of 103ºF, chills, nausea, vomiting, and hypotension. The patient also produced excessive yellowish sputum, which he says has increased in quantity over the past 3 days. A chest x-ray showed extensive infiltrates in the left lower lung. Multiple blood cultures and culture of the sputum yielded S. pneumoniae. What is the presumptive diagnosis for this patient? What...
