It is covered under the umbrella term of Chronic Obstructive Pulmonary Disease (COPD).The COPD spectrum ranges from Emphysema to Chronic Bronchitis and it occurs when the airways become inflamed and the air sacs in your lungs are damaged. Emphysema is most likely to develop in cigarette smokers, but cigar and pipe smokers also are susceptible. View our pathophysiology and schematic diagrams. Central to the pathophysiology of emphysema is the presence of airflow obstruction and lung and chest hyperinflation. Emphysema (loss of alveolar structure); ...

Airflow Limitation Induced by airway inflammation Bronchoconstriction- Bronchial smooth muscle contraction that quickly narrows the airways in response to exposure to a variety of stimuli Airway hyperresponsiveness- an exaggerated bronchoconstrictor response to stimuli Airway edema- as the disease becomes more persistent and inflammation become more progressive, … Suspect COPD in people aged over 35 years with a risk factor (such as smoking, occupational or environmental exposure) and one or more of the following symptoms:. Diagnosis of COPD is based on typical clinical features supported by spirometry. Chronic obstructive pulmonary disease (COPD) affects the lungs and your ability to breathe.
