A healthcare professional who works in a senior center knows about the effects of aging on the pulmonary system, which include which of these? (Select all that apply.) A)Decreased chest wall compliance B)Decreased lung recoil C)Reduced ventilatory reserve D)Decreased partial pressure of arterial oxygen (PaO₂) E)Reduced respiratory rate

Question

Quizplus · Accepted Answer

Aging affects the mechanical aspects of ventilation by decreasing chest wall compliance and elastic recoil of the lungs. Changes in these elastic properties reduce ventilatory reserve. Aging causes the PaO? to decrease but does not affect the partial pressure of arterial carbon dioxide (PaCO?) or respiratory rate.
