The WatchPat is a take home device similar to a watch. This sleep study is performed in the privacy and comfort of your home. It is easy to use and will provide us with all the information necessary to make a diagnosis for Sleep Apnea. The test is sent to a Sleep Medicine Doctor and the results provide information on how well you slept, what positions you sleep in, if and when snoring occurs, blood oxygen levels, pulse, and the duration of your sleep stages. The combined information is used to determine if a patient has sleep apnea and it determines the severity.
