ABSTRACT:
An endotracheal tube has a temperature sensor positioned proximal of a patient's larynx when the tube is in use. Thus, the sensor overlies the tongue. In view of the high vascularity of the tongue, the sensor provides an accurate reading of the patient's body temperature and responds quickly to temperature changes. A heat insulator inhibits heat transfer from the interior of the endotracheal tube to the sensor, and an electrical insulator electrically isolates the sensor from the tongue. In a first embodiment, the sensor is linear in configuration, and in a second embodiment the sensor is serpentine in configuration to increase the surface area of the contact between the sensor and the tongue. A third embodiment adds an oxymeter. In additional embodiments, the sensor is placed on other highly vascular regions of the body, or where an artery is present. The sensor may also be positioned within a preselected vein or artery.
