rdi2pns
Label
Apnea-Hypopnea Index (Non-Supine): Apneas with >=2% oxygen desaturation and with or without arousal+ hypopneas with > 30% flow reduction and with >=2% oxygen desaturation and with or without arousal / hour of sleep in non-supine position from type II polysomnography
Description

Calculated - Summary metric of sleep disordered breathing events

Calculation
rdi2pns = 60 * ( hrop2 + hnrop2 + carop2 + canop2 + oarop2 + oanop2 ) / ( remepop + nremepop )
Units
events per hour
