Hypopnea detection

特許 係属中 Hypopnea (mostly spelled hypopnœa) is a medical term for a disorder which involves episodes of overly shallow breathing or an abnormally low respiratory rate. Hypopnea is less severe than apnea (which is the complete cessation of breathing). It may likewise result in a decreased amount of air movement into the lungs and can cause oxygen levels in the blood to drop. It more commonly is due to partial obstruction of the upper airway.
