Types of Obstructive Sleep Apnea (OSA)
Types of Obstructive Sleep Apnea
There are 3 types of obstructive breathing events:
Apnea: A period of at least 10 seconds during which there is a complete or near complete pause in breathing.
Hypopnea: A decrease in airflow lasting at least 10 seconds.
Respiratory effort related arousal (RERA): A limitation in breathing that results in increased respiratory effort and culminates in an arousal; it does not meet the criteria from an apnea or hypopnea.
Clinical trials are research studies that evaluate a new medical approach, device, drug, or other treatment. As a Stanford Health Care patient, you may have access to the latest, advanced clinical trials.
Open trials refer to studies currently accepting participants. Closed trials are not currently enrolling, but may open in the future.
