Abstract: An apparatus and method for measuring the concentration of carbon dioxide in respiratory gases. The apparatus is a non-dispersive gas analyzer (100) attached in series with the respiratory airway which is universally compatible with any host system. The analyzer (100) includes a housing (102) which supports a sample cell containing the respiratory gases, and which contains an infrared radiation source (130) encased in shock absorbing material, means for directing the radiation into a collimated beam through the sample cell, means (145) for splitting the beam and directing it towards two infrared detectors (142, 146) for measuring the amount of absorption of carbon dioxide in the sample cell. The analyzer has two heating servos (118, 152), one regulating the temperature of the sample cell windows to inhibit condensation build-up and one regulating the ambient temperature surrounding the detectors (142, 145) to ensure more accurate measurements. Calibration means within the analyzer housing ( 102) stores and provides information characterizing performance parameters of the analyzer (100).
