ABSTRACT:
A reflectance oximeter is so mounted to the upstream or proximal side of a laryngeal mask as to face the posterior wall of the pharynx when the laryngeal mask has been positioned to perform its function of sealed, exclusive airway communication with the laryngeal inlet. Thus positioned, radiation from the oximeter can utilize local back-bone features as a reflector, for two-way passage of the radiation through tissue which characterizes the posterior wall of the pharynx. Moreover, the oximeter-observation region is within the body, so that ambient light has no degrading effect, and changes in oxygen saturation will be detected earlier than by use of any peripherally placed oximeter probe.
