Abstract

An aviation or similar headset having an ear cup includes an oximeter. In one embodiment, the oximeter is mounted to a cushion of the ear cup so as to be generally coplanar thereweith. When the headset is worn, the ear cup is located about the ear of the wearer and the oximeter is positioned proximal to or against the skin of the wearer near the ear. The oximeter obtains blood-oxygen content information. The oximeter output may be provided to an oxygen delivery control apparatus arranged to control the flow of oxygen to a user in an open-loop breathing system including an oxygen supply and a delivery apparatus for delivering supplemental oxygen to a user.

Claims

1. A method of obtaining blood-oxygen content level data comprising the steps of:

providing a headset having at least one ear cup and an oximeter mounted to said ear cup;

positioning the headset on the head of a wearer, said at least one ear cup positioned about an ear of the wearer;

positioning said oximeter proximal to a surface of the skin of said wearer adjacent said ear; and

obtaining blood-oxygen content level information using said oximeter.

2. The method in accordance with claim 1 including the step of outputting said information as an analog signal via a cable.

3. The method in accordance with claim 1 wherein said oximeter is a reflectance type oximeter.

4. The method in accordance with claim 1 including the step of pressing a surface of said oximeter against said surface of said skin.

5. The method in accordance with claim 4 wherein said headset has pair of opposing first and second ear cups connected to one another and said step of pressing comprises generating a biasing force by spreading said first and second ear cups away from one another when said headset is placed on the head of the wearer.

6. In combination, a headset and oximeter sensor, said headset including at least one ear cup, said at least one ear cup including a cushion having an outwardly facing surface having an inner circumference and outer circumference, said cushion for location about an ear of a wearer, said oximeter mounted to said cushion of said at least one ear cup, said oximeter having an outer surface which is generally co-planar with said outwardly facing surface of said cushion.

7. The combination in accordance with claim 6 wherein said headset includes a pair of ear cups and said oximeter is mounted to one of said ear cups.

8. The combination in accordance with claim 6 wherein said oximeter is a reflectance-type oximeter sensor.

9. The combination in accordance with claim 6 wherein said oximeter provides an output signal to a cable.

10. The combination in accordance with claim 9 wherein said cable includes a first conductor and a second conductor, and said oximeter provides said output signal to said first conductor and a microphone is mounted to said at least one ear cup and said microphone provides an output to said second conductor.

11. The combination in accordance with claim 6 wherein said oximeter provides an output signal to an oxygen delivery control apparatus for controlling the flow of oxygen to a user in an open-loop breathing system including an oxygen supply and a delivery apparatus for delivering supplemental oxygen to said user.
