Which of the following is a true statement
Hypoventilation causes hypocapnia
Hyperventilation causes hypercapnia
Hyperventilation causes hypocapnia
Hyperventilation results in an increased PaCO2
The Correct Answer is C
Hyperventilation refers to an increased rate and depth of breathing, which results in excessive elimination of carbon dioxide (CO2) from the body. Carbon dioxide is an acidic gas that helps regulate the pH of the blood. When too much CO2 is lost through hyperventilation, it causes a decrease in the partial pressure of carbon dioxide in the blood (PaCO2), leading to a condition called hypocapnia.
Hypocapnia can cause symptoms such as lightheadedness, dizziness, and tingling in the fingers and toes.
