Abstract: Physiologic sensors and methods of application are described. These sensors function by detecting recently discovered variations in the spectral optical density at two or more wavelengths of light diffused through the skin. These variations in spectral optical density have been found to consistently and uniquely relate to changes in the availability of oxygen in the skin tissue, relative to the skin tissue's current need for oxygen, which we have termed Physiology Index (PI). Current use of blood gas analysis and pulse oximetry provides physiologic insight only to blood oxygen content and cannot detect the status of energy conversion metabolism at the tissue level. By contrast, the PI signal uniquely portrays when the skin tissue is receiving ‘less than enough oxygen,’ just the right amount of oxygen,? or ‘more than enough oxygen’ to enable aerobic energy conversion metabolism.
