A Home Sleep Apnea Test (HSAT) is a limited channel sleep test performed in your home and used to diagnose obstructive sleep apnea (OSA).
Our Sleep Center uses a number of devices for the HSAT.
Each HSAT device is a bit different. Some use various discs with wires attached called leads to detect heart rhythm. Some use stretchy bands will be placed around your chest and stomach to detect breathing as well as two small sensors positioned near your nose and mouth to detect nasal and oral breathing and an oxygen monitor on your index finger to detect your oxygen levels. One uses primarily a wrist monitor with an oxygen sensor on your finger. None of the leads or sensors hurt, irritate or damage your skin.
Our tech will demonstrate to the patient how to perform the test, including how to use the device and all equipment properly. The patient goes home with the HSAT device and paper instructions along with numbers for troubleshooting. The patient performs the test on the night that they pick up the device and returns it the next day to the Sleep Lab. The data obtained is stored on the device and is uploaded at the sleep center the following day. Once returned, the technician will download the device and create a detailed report based on the results.
