Abstract
A method for taking reflectance oximeter readings within the nasal cavity and oral cavity and down through the posterior pharynx. The method utilizes a reflectance pulse oximeter sensor that preferably is resistant to bodily fluids to contact one of these capillary beds for the taking of readings and then forwarding of these readings to an oximeter for display. The method includes inserting a reflectance pulse oximeter sensor into a cavity within a subject's skull and contacting a capillary bed disposed in the cavity with the reflectance pulse oximeter sensor.
