Abstract:
1. A dissolved carbon dioxide sensor comprising: a sensor body adapted for use associated with a patient's tissue; one or more emitters disposed on the sensor body, wherein each emitter is adapted to emit at least one wavelength of light between 4200 nm and 4350 nm; and one or more detectors disposed on the sensor body, wherein each detector is adapted to detect the wavelength of light and generate a signal correlated with a level of dissolved carbon dioxide in the patient's tissue, wherein each detector is positioned to have an optical distance of 200 micrometers or less with respect to at least one emitter, and wherein there are no other detectors that detect the wavelength of light disposed on the sensor body that do not have the optical distance of 200 micrometers or less with respect to at least one emitter.
