Patent abstract
A patient monitor has multiple sensors adapted to attach to tissue sites of a living subject. The sensors generate sensor signals that are responsive to at least two wavelengths of optical radiation after attenuation by pulsatile blood within the tissue sites. A patient monitor uses the sensor signals to determine changes in constant oxygen consumption as an indication of changes in metabolism at the tissue cite.
