ABSTRACT:
An infrared fluid analyzer for the detection of end tidal CO.sub.2. The analyzer is comprised of an IR source that irradiates a chamber filled with gas. CO.sub.2 present in the chamber absorbs the IR radiation at a certain wavelength. An IR detector determines the amount of IR radiation passing through the chamber unabsorbed and produces a signal corresponding to the CO.sub.2 in the chamber. At predetermined intervals a zero gas is reintroduced into the chamber for the system to be recalibrated. A span gas is only needed initially for calibration purposes.
