    Abstract: A respiratory gas concentration measuring apparatus includes a chopper having a first filter for passing therethrough light from a light source and having a first wavelength which can be absorbed by a gas to be measured and a second filter for passing therethrough light from the light source and having a second wavelength which cannot be absorbed by the gas. The chopper is rotatable to position the first and second filters alternately in a light path. The light having passed through the filters is converted by a photodetector into an electric signal. A first detector detects an output from the first filter based on the electric signal, and a second detector detects an output from the second filter based on the electric signal. The apparatus has a power computing circuit for raising an output from said second detector to an mth power, m being a power exponent preset in the power computing circuit, and a divider circuit for dividing an output from the first detector by an output from the power computing circuit. The power exponent m is the ratio between a temperature-dependent coefficient .theta..sub.1 of the output of the first detector which varies exponentially with a temperature variation and a temperature-dependent coefficient .theta..sub.2 of the output of the second detector which varies exponentially with a temperature variation.

    Abstract: A nasal mask is adapted to attached on a face of a subject so as to cover a nose of the subject. A shell has a contact edge adapted to be brought into close contact with the face of the subject, thereby forming a sealed space therein. An attachment portion is disposed in the shell and has an inner space. The attachment portion is configured to detachably engage with a sensor disposed outside the shell and operable to measure concentration of carbon dioxide gas expired from the nostrils. A guide member is disposed inside the shell and forming a passage adapted to introduce expired gas from the nostrils into the inner space. The shell is formed with an inlet adapted to introduce external gas into the sealed space. The expired gas is guarded by the guide member from the external gas introduced through the inlet. The attachment portion is formed with an outlet adapted to discharge the expired gas from the inner space to the sealed space.

    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.
