Abstract: In a sensor for detecting a carbon dioxide gas in an expiration gas of a living body, an airway case is adapted to be disposed below nostrils of the living body, and formed with an airway passage extending across an optical axis of a light beam emitted from a right emitter of the sensor. A mouth guide is adapted to be disposed in front of a mouth of the living body so as to define a space communicated with the airway passage. The mouth guide is pivotably supported on the airway case. A retainer is adapted to retain an oxygen supply tube on the airway adapter body in such an attitude that an oxygen gas supplied from prongs of the oxygen supply tube is not directly injected into the nostrils.

Abstract: A method and apparatus for applying infrared radiation to a respiratory gas and detects a signal associated with the quantity of transmitted radiation for measuring the concentration of CO2 in the respiratory gas. The capnometer detects a maximum value of the detection signal from the thermal detector during the present inspiration phase, stores the detected maximum value in RAM, performs the first approximation, Kalman filtering or some other suitable method to compute a corrected value that is valid for the time being until a maximum value is detected in the next inspiration phase, and determines a density signal by calculating the difference between the corrected value and the detection signal.
