Hypoventilation

Hypoventilation is breathing that is too shallow or too slow to meet the needs of the body.

If a person hypoventilates, the body's carbon dioxide level rises. This causes a buildup of acid and too little oxygen in the blood.

Symptoms

A person with hypoventilation might feel sleepy.
