Arousal responses to inspiratory resistive loading during REM and non-REM sleep in normal men after short-term fragmentation/deprivation.

The arousal response to inspiratory resistive loading in normal men is known to be high during REM sleep compared to non-REM sleep. We investigated whether we could observe the same pattern, i.e. brisk arousal from REM sleep compared to non-REM sleep, in normal subjects who had undergone short-term sleep fragmentation/deprivation prior to the investigation. The arousal response to the repeated application of an external inspiratory resistance of...
