ABSTRACT:
A small battery-operated oximeter noninvasively measures tissue oxygenation. This oximeter employs a high intensity, very short duration light pulse that penetrates clothing of a patient. A photodetector assembly of the oximeter is responsive to light reflected through clothing of the patient. The oximeter optically filters the reflected light. A ratio of the intensity of reflected red light to the intensity of reflected infrared light indicates tissue oxygenation of the patient.
