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.
