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.
REM, or rapid eye movement sleep is an important part of a human being's normal sleep pattern. This is the stage of sleep when people often dream. When someone hasn't gotten enough REM sleep, they can suffer the effects of sleep deprivation, which includes mental fatigue, migraines, and increased stress.
