Question

If ventilation is increased so that arterial PCO2 is decreased, the condition is called:

a) Hyperventilation
b) Hypercapnia
c) Hypocapnia
d) Hypoventilation

Answer 1

Hypocapnia is the condition that occurs when ventilation is increased, leading to a decrease in arterial PCO2. It is characterized by abnormally low blood carbon dioxide levels and high (alkaline) blood pH.

Step-by-step explanation:

The condition that occurs when ventilation is increased, leading to a decrease in arterial PCO2, is called hypocapnia. This is characterized by abnormally low blood carbon dioxide levels and high (alkaline) blood pH. It can be caused by hyperventilation, which is an increased ventilation rate that is independent of the body's oxygen needs.
