What is the equation for TRT - -(lights on-lights out) / 2
-What is the equation for TWT - -(total wake epochs) / 2
-What is the equation for TST - -(total of all sleep epochs) / 2
-What is the equation for SE% - -(TST / TRT) x 100 = SE%
-How do you figure sleep stage percentage - -total epochs in sleep stage /
TST x 100
-How do you figure REM latency - -REM onset - SO / 2
-What is the equation for events - -total # of events / TST x 60
-If lights on was at epoch 825 and lights out was at epoch 25, what is your
TRT - -(825-25) / 2 = 400 min
-Total wake epochs were 205, what would be your TWT - - = 102.5
min
-N1 was 45 epochs, N2 was 380 epochs, N3 was 55 epochs, REM was 115
epochs and your TRT was 800 epochs, what is your TST - - = 297.5
min
-If your TST was 297.5 min and your TRT was 400 min, what is your SE% - -
(297.) x 100 = 74%
-SO was at epoch 52 and LO was at epoch 25, what is your sleep latency - -
(52-25) / 2 = 13.5 min
-SO was at epoch 52 and REM onset was 272 epochs in to the PSG, what is
your REM latency - -52 - 272 = 220, = 110 min
-N1 sleep lasted for 45 epochs, what is your total time in N1 - - = 22.5
min
-N1 sleep lasted for 45 epochs and your TST was 297.5 min in length, what
percentage of time was spent in N1 sleep - -(22..5) x 100 = 7.6 %
