Abstract: A system for performing near infrared spectroscopy (NIRS) monitors tissue oxygenation and/or hemodynamics. The system comprises a sensor coupled to a controller and/or processing device. The sensor comprises a light source which is operable to emit light of various distinct wavelengths and a detector which is operable to collect corresponding backscattered light.

Abstract: The present disclosure relates to systems and processes for optimizing the detection of a patient's heartbeats, which may be useful in detection of the patient's oxygen saturation, as well as systems and processes for improving and optimizing the PPG signal quality of those patients with highly pigmented skin. In various embodiments, the process may comprise the steps of: receiving, from a radio, red data, infrared (IR) data, and a series of heartbeats associated with a time period; computing a series of peaks of the red data and IR data for the time period; computing a subset of the red data and IR data; estimating an oxygen saturation percentage (SpO2%) for the patient by computing an optical ratio of the red data and IR data included in the subset; and displaying on a computer screen the estimated SpO2% for the patient.
