Apnea-Hypopnea Index: (All apneas with no oxygen desaturation threshold used and with or without arousal + hypopneas with > 30% flow reduction and with >= 3% oxygen desaturation and with or without arousal) / hour of sleep from type I polysomnography
Calculated - Summary metric of sleep disordered breathing events. |

Obstructive Apnea Hypopnea Index: (Obstructive apneas with no oxygen desaturation threshold used and with or without arousal + hypopneas with > 30% flow reduction and >= 3% oxygen desaturation and with or without arousal) / hour of sleep from type I polysomnography
Ratio of the count of all obstructive apneas (all desaturations) plus the count of hypopneas associated with at least a >=3% oxygen desaturation to the total sleep time expressed in hours. |
