Abstract: A respiration monitoring system includes a thermoelectric generator that may be mounted within a mask enclosure or free-standing, covering all or part of the nose and/or mouth of a subject. A first temperature sensor is attached to the thermoelectric generator for measuring the subject's breath. A power controller develops a difference between a preset temperature and the subject's breath temperature that is then inserted into a feedback error signal and then into a power controller which regulates the power to the thermoelectric generator to maintain a preset temperature.

Abstract: A system for monitoring the breathing status of a patient comprises a first temperature sensor and a second temperature sensor. The first temperature sensor is arranged to measure the temperature of the breathing gas of a patient. The second temperature sensor is arranged to measure an ambient temperature of the patient's surroundings. A controller is included, wherein the controller is programmed to determine a plurality of breathing-gas temperatures over time by way of a first signal received from the first temperature sensor and at least one ambient temperature using a second signal received from the second temperature sensor. The controller is programmed to analyze the plurality of breathing-gas temperatures and the at least one ambient temperature to determine a breathing status of the patient. The present invention may be embodied as a method for monitoring the breathing status of a patient.
