A wearable polysomnograph with a wireless RF link to a PC, portable solid-state recorder, or the Internet is presented. The device removes the need for off body cabling during sleep studies. The body worn package is 5.8"/spl times/3.15"/spl times/0.84" and weighs less than 8 ounces. It can be worn on the chest of a sleeping patient. Eighteen sensor channels including built-in SpO/sub 2/ are processed and transmitted for up to 15 hours using two AA alkaline batteries. Three receiver modalities collect data to a PC, battery powered solid-state recorder, or the Internet.
