Abstract:
A reflective SpO 2  measurement system includes a light source that emits light of at least a first and second wavelengths, and one or more detection devices forming a close detector positioned at a first distance from the light source and a far detector positioned at a second distance from the light source, wherein the second distance is greater than the first. The SpO 2  measurement system is configured to operate in a high power mode to determine a calibration factor based on the comparison of light reflections detected by the close detector and the far detector. The system is further configured to operate in a low power mode to generate a low intensity light pulse, and detect a close reflection of the low intensity light pulse with the close detector. An SpO 2  is then determined based on the close reflection of the low intensity light pulse and the calibration factor.

Claim (Index 17):
The method of  claim 12 , wherein the at least one light source comprises three light sources, and one detection device forms the close detector, the middle detector, and the far detector;\n wherein the close detector is formed by the detection device operating to receive light from a first light source generating the low intensity light pulse and positioned at the first distance from the detection device, the middle detector is formed by the detection device operating to receive light from a second light source generating the medium intensity light pulse and positioned at the middle distance from the detection device, and the far detector is formed by the detection device operating to receive light from a third light source generating the high intensity light pulse and positioned at the second distance from the detection device; wherein the step of generating at least one light pulse with one or more light sources for determining the calibration factor further comprises:\n generating the low intensity light pulse with the first light source and measuring the close reflection; \n generating the high intensity light pulse with the far detector and measuring the far reflection; and \n wherein the calibration factor is determined based on the close reflection of the low intensity light pulse and the far reflection of the high intensity light pulse.
