Abstract:
1. A method for calculating blood oxygen saturations, the method comprising: emitting a plurality of light signals from light emitters; receiving a first light signal at a first light detector, wherein the received first light signal comprises a first set of impulses corresponding to a first wavelength of emitted light emitted from the light emitters and a second set of impulses corresponding to a second wavelength of light emitted from the light emitters; receiving a second light signal at a second light detector; calculating a pulse blood oxygen saturation based on a first subset of the first and second sets of impulses of the received first light signal, using a processor, wherein the calculation of pulse blood oxygen saturation is not based on a second subset of the first and second sets of impulses; and calculating a regional blood oxygen saturation based on the second subset of the first and second sets of impulses and the received second light signal, using a processor, wherein the calculating a pulse blood oxygen saturation and the calculating a regional blood oxygen saturation are done substantially simultaneously.
