Abstract
A computer system for simultaneously sampling multiple light channels is configured to emit a first pulse-oximetry light signal from a first light source and to emit a second pulse-oximetry light signal from a second light source. The computer system then captures a combined pulse-oximetry signal from both the first pulse-oximetry light signal and the second pulse-oximetry light signal simultaneously at a photoreceptor sensor. The computer system identifies information within the combined pulse-oximetry signal, wherein the first light source and the second light source capture different attributes of the information.
