Abstract
A sensor includes a sensor pad that allows air and moisture to diffuse from a patient's skin. A light source is disposed on the sensor pad is configured to generate near-infrared light. A light detector disposed on the sensor pad is configured to detect near-infrared light generated by the light source.
Claims14
A sensor comprising:
- a sensor pad having a bottom surface configured to be applied to a patient and a top surface opposite said bottom surface, wherein at least a portion of said sensor pad is formed from a breathable material in a configuration such that air and moisture diffuse laterally from said sensor pad at a rate greater than any diffusion of air and moisture through said top surface;
- a light source disposed on the sensor pad and configured to generate near-infrared light;
- and
- a light detector disposed on the sensor pad and configured to detect near-infrared light generated by the light source.

A sensor comprising:
- a sensor pad at least partially formed from an open cell breathable material having a thickness and a cell size configured relative to each other to laterally diffuse air and moisture from a patient's skin at a rate that is equivalent to at least a lateral diffusion rate achieved by a polyurethane open cell foam with a cell size of 0.2-0.5 mm and a thickness of 1-2 mm;
- a light source disposed on the sensor pad and configured to generate near-infrared light;
- and
- a light detector disposed on the sensor pad and configured to detect near-infrared light generated by the light source.
