After evaluating if a patient has a high likelihood of having a sleep breathing disorder, a medical doctor can order a Home Sleep Test (HST). Home sleep tests allow physicians to monitor your sleep patterns in the comfort of your own home, and without interrupting your normal nightly routine. The HST device is generally worn as a belt, while finger probes connected to the device gather your data and vital signs. The information is stored on a removable memory card and downloaded for a board-certified sleep physician to analyze and recommend treatment.
