Abstract
|
|
|
|
Aging results in various changes in pulmonary function. The structural changes include reduced compliance of chest wall and lung parenchyma, which results in air-trapping, increased functional residual capacity and work of breathing. Respiratory muscle strength decreases with age and can impair effective cough, which is important for secretion clearance. Aging is associated with progressive decline in pulmonary function. Decreased sensitivity of hypoxia and hypercapnia with age leads to a diminished ventilator response, which can give rise to the ventilatory failure during high demand states (such as pneumonia, heart failure). Therefore understanding of these changes in an elderly patient is essential to the implementation of appropriate pulmonary rehabilitation.
