THE COLLISION BROADENING EFFECT OF NITROUS OXIDE UPON INFRARED ANALYSIS OF CARBON DIOXIDE DURING ANESTHESIA

^* Model 16 Gas Analyzer, Liston-Becker Division, Beckman Instruments Company, Springdale, Connecticut.

^†Dr. Max Liston of Beckman Instruments Company suggested and fabricated the detector cells charged with carbon dioxide tension of 10 mm. of mercury.

^‡Ohio Chemical & Surgical Equipment Co., New York, New York.

^§Essentially similar results were obtained by Dr. Max Liston who carried out a similar set of determinations based upon reproducible mixtures of carbon dioxide in diluent gases produced by pressure measurements rather than volume measurements.
