a less well-defined entity, but usually is considered a diminution in airflow which results in hypoxemia and results in an arousal
a milder reduction in airflow accompanied by a reduction in oxygen saturation
episode of decreased rate and depth of breathing
hy-pop'ne-uh Decreased in amount of air breathed per minute. Depth of breathing, rather than rate, usually is decreased. Shallow airflow due to the lack of thoracic and abdominal effort; generally accepted as 50% loss of airflow for 10 or more seconds. Term: Definition: Description: . .
an episode of abnormally slow or shallow respiration during sleep that lasts longer than 10 seconds. Hypopnea differs from apnea in that some airflow is present.
Breathing that is less than normal efficiency.
decreased breathing with at least 50% reduction in air flow.
Hypopnea is partial (30-50%) cessation of airflow at the nose and / or mouth.
An episode of diminished breathing during sleep, caused by a partial airway obstruction, and resulting in arousal. Usually accompanied by oxygen desaturation. Hypopneas may be just as serious as apneas and have the same troublesome effects.
slow or shallow breathing
when airflow is less than half its normal volume (the airway is not completely obstructed but breathing is not normal).
a partial cessation of breathing, whereas an apnea is a complete cessation. The clinical definition of a hypopnea is a 50% to 90% cessation of breathing, and an apnea is a 91% to 100% cessation of breathing.
Breathing that is shallower or slower than normal during sleep
