A sleep apnea monitor includes an SaO2 sensor, a breathing sensor, a snoring sensor, and a head position sensor, all of which are mounted to a headgear. The breathing sensor preferably includes a piezo-electric film formed of a generally cylindrical shape positioned between the nose and mouth of the subject such that exhaled air warms the film and generates an electric signal indicative of the brathing pattern of the subject. Preferably, the region bounded by the piezo-electric film is used as a resonant cavity which is acoustically coupled to a microphone included in the snoring sensor. In one embodiment, data is logged from the sleep apnea monitor at the rate of one measurement for each pulse beat of the subject. In this way, data recording is synchronized with a physiological variable.

A sensor positioning device for an oximeter of the type comprising an emitter having at least one light source, a receiver having at least one photosensor, and means for monitoring the receiver to measure selected body parameters, said device comprising: a headband configured to rest on the head of a subject; means for mounting the emitter and the receiver to the headband in side-by-side relationship such that both the emitter and the receiver are directed toward the forehead of the subject; means, included in the mounting means, for resiliently biasing the emitter and receiver into contact with the forehead of the subject; a breath sensor; and means for mounting the breath sensor to the headband to position the breath sensor to respond to air exhaled by the subject.
