Device and Method for Monitoring of Absolute Oxygen Saturation and Tissue Hemoglobin Concentration
First Claim
1. A method of detecting signals in a medical device, comprising:
- detecting emitted light scattered by a volume of tissue delivered along a first pathway and a second pathway different from the first pathway;
detecting emitted light scattered by a volume of tissue delivered along a third pathway and a fourth pathway different from the third pathway;
determining a first uniformity corresponding to the emitted light detected along the first pathway and the second pathway;
determining a second uniformity corresponding to the emitted light detected along third pathway and the fourth pathway;
determining a total uniformity in response to the determined first uniformity and the determined second uniformity; and
altering sensing by the device in response to the determined total uniformity.
