Polysomnography (PSG), a type of sleep study, is a multi-parametric test used in the study of sleep and as a diagnostic tool in sleep medicine. The test result is called a polysomnogram, also abbreviated PSG.
Test Overview. Sleep studies are tests that record what happens to your body during sleep. The studies are done to find out what is causing your sleep problems. Sleep studies can also determine whether you have a problem with your stages of sleep. The two main types of sleep are non-rapid eye movement (NREM) and rapid eye movement (REM). Normally, NREM and REM alternate 4 to 5 times during a night's sleep.
