Abstract: An improved gas analyzer system and method for detecting and displaying the constituent gases of a respiratory gas stream, the system comprising an optical bench comprising a gas pathway for the flow of a gas stream, a flow shaping inlet (228) three infrared detection (206, 208, 210) channel assemblies for measuring the partial pressures of constituent gases, and measuring sensitivity changes in the detectors of the three infrared detection channel assemblies (206, 208, 210), a pressure sensor (274, 276) for measuring the pressure within the gas pathway, a temperature sensor for measuring the temperature within the optical bench, a flow rate sensor for measuring the gas flow rate through the gas pathway; analog processing circuitry for processing the detected partial gas pressures, sensitivity changes, the measured values for pressure, temperature, and flow rate; and display processing circuitry.
