Hypopnea overview

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]

Hypopnea is a medical term for abnormally shallow breathing or slow respiratory rate. This differs from apnea in that there remains some flow of air. Hypopnea comes from the Greek roots hypo- (meaning low, under, beneath, down, below normal) and pnoe (meaning breathing). Literally it means underbreathing.
