poai_rem under Sleep Monitoring/Polysomnography/Arousal in MROS variables
REM Arousal Index - total arousals in REM sleep per hours of REM sleep(Total number of arousals in REM sleep) / (hours of REM sleep)
ai_rem under Sleep Monitoring/Polysomnography/Arousals in SOF variables
Total arousals in rapid eye movement sleep (REM) per hours of rapid eye movement sleep (REM)
poai_nre under Sleep Monitoring/Polysomnography/Arousal in MROS variables
Non-REM Arousal Index - total arousals in non-REM sleep per hours of non-REM sleep [(Total number of arousals in non-REM sleep) / (hours of non-REM sleep)]
remnrempr under Sleep Monitoring/Polysomnography/Signal Quality in SOF variables
Scorer noted that there was a problem differentiating rapid eye movement sleep (REM) and non-rapid eye movement sleep (NREM).
nap5_rem under Sleep Monitoring/Other Sleep Tests/Multiple Sleep Latency Test (MSLT) in WSC variables
Clinical MSLT only: the 5th nap was only conducted if the participant had REM sleep in one of the first 4 naps. Variable from a Multiple Sleep Latency Test (MSLT), Roehrs & Roth 1992 (PubMed ID: 1552009).Search for all Multiple Sleep Latency Test variables within this dataset
rdirempsgden under Sleep Monitoring/Polysomnography/Respiratory Event Counts in APPLES variables
PSG Total Minutes of REM sleep - REM RDI Denominator
rdimrem0p under Sleep Monitoring/Polysomnography/Apnea-Hypopnea Indices in CHAT variables
[(total number of apneas and hypopneas in rapid eye movement sleep (REM)) / (hours of rapid eye movement sleep (REM))]
rdimrem2p under Sleep Monitoring/Polysomnography/Apnea-Hypopnea Indices in CHAT variables
[(total number of apneas and hypopneas in rapid eye movement sleep (REM) associated with >= 2% desaturation) / (hours of rapid eye movement sleep (REM))]
rdimrem3p under Sleep Monitoring/Polysomnography/Apnea-Hypopnea Indices in CHAT variables
[(total number of apneas and hypopneas in rapid eye movement sleep (REM) associated with >= 3% desaturation) / (hours of rapid eye movement sleep (REM))]
rdimrem4p under Sleep Monitoring/Polysomnography/Apnea-Hypopnea Indices in CHAT variables
[(total number of apneas and hypopneas in rapid eye movement sleep (REM) associated with >= 4% desaturation) / (hours of rapid eye movement sleep (REM))]
rdimrem5p under Sleep Monitoring/Polysomnography/Apnea-Hypopnea Indices in CHAT variables
[(total number of apneas and hypopneas in rapid eye movement sleep (REM) associated with >= 5% desaturation) / (hours of rapid eye movement sleep (REM))]
remnrempr under Sleep Monitoring/Polysomnography/Signal Quality in CHAT variables
1=Sleep staging problem - scoring rapid eye movement sleep (REM)/non-rapid eye movement sleep (NREM) unreliable (when identification of Stage rapid eye movement sleep (REM) is unreliable (usually due to poor or missing EMG or when both EOGs are absent))
remlaip under Sleep Monitoring/Polysomnography/Sleep Architecture in CHAT variables
Total time from beginning of sleep to first epoch of rapid eye movement sleep (REM) (data can be inaccurate if scorer has not set sleep onset rule properly in compumedics software)
nsrr_ttlprdsp_s1sr under Harmonized/Polysomnography/Sleep Architecture in MESA variables
Harmonized by the NSRR team. Source: :rem_lat15:
remarunrel under Sleep Monitoring/Polysomnography/Signal Quality in CFS variables
Due to signal problems, scorer was unable to reliably assess arousals in stage REM. The scoring of arousals in stage REM was determined to be unreliable.
