Abstract

Systems and/or methods for diagnosing sleep disorders in a patient are provided. In certain example embodiments, articles of bed clothing and/or bed sheets comprising sensors operable to obtain patient condition data related to sleep-disordered breathing (SDB) are provided to patients. The patient condition data is stored to a data recorder operably connected to the sensors. The sensors and the data recorder may communicate wirelessly. The bed clothing (e.g. wearable articles of clothing, bed sheets or mats, pillows, etc.) may have batteries and/or battery fibers disposed therein to power the sensors. In certain example embodiments, a bed sheet may be physically connected to a power supply and/or the data recorder. In certain example embodiments, a bed sheet and articles of bed clothing both may be provided to the patient.
