ABSTRACT:
A pulse oxymeter for measuring a blood oxygen saturation of a subject, including a first device for emitting toward a body portion of the subject a first light having a first wavelength and a second light having a second wavelength different from the first wavelength, a second device for detecting an intensity of each of the first and second lights transmitted through, or reflected by, the body portion of the subject and generating a photoelectric pulse wave signal representative of the detected intensity of each of the first and second lights, a third device for determining a blood oxygen saturation of the subject based on the pulse wave signals corresponding to the first and second lights, a probe which supports the first and second devices and is adapted to contact the body portion of the subject, and a warming device for warming the body portion of the subject.
