I called Nationwide Medical after my current CPAP supplier was no longer an approved Medicare vendor. I gave all my information to the man I spoke to, including the model and serial numbers of the machine I was using, my doctor's names and phone numbers, and my Medicare number.
REM rebound. REM rebound is the lengthening and increasing frequency and depth of rapid eye movement (REM) sleep which occurs after periods of sleep deprivation. When people have been prevented from experiencing REM, they take less time than usual to attain the REM state.
In electroencephalography, the REM phase of sleep is easily identified by its paradigmatic fast, small-amplitude waves. (Also typical are the rapid eye movements for which the REM phase is named.) For this reason REM sleep is sometimes also called âactive sleep.â Many sleep experts think that these eye movements are in some way related to dreams.
