WatchPAT’s positive predictive values in stages wake, light sleep (N1 + N2), deep sleep (N3) and REM sleep.
| WP vs RPSGT#1 | WP vs RPSGT#2 | RPSGT#2 vs RPSGT#1 | |
|---|---|---|---|
| Wake | 71.2 | 71.9 | 96.0 |
| Light sleep | 67.9 | 64.4 | 88.8 |
| Deep sleep | 29.6 | 36.8 | 85.3 |
| REM sleep | 62.2 | 59.7 | 92.7 |
Percentage of WatchPAT scored epochs where agreement exists with PSG out of the total number of WatchPAT scored epochs in the specified stage.
WP = WatchPAT, RPSGT#1 and RPSGT#2 = polysomnographies scored by polysomnography technician number one and two, respectively. N1 + N2 = non rapid eye movement sleep (NREM) stage one and two, N3 = NREM stage 3, REM = rapid eye movement.
