Abstract

Detailed techniques are presented for a method of alveolar CO2 determination which utilizes a fractional to-and-fro continuous sampling method and a rapid infrared absorption gas analyzer with a direct recording system. The validity of the method was established by comparing the alveolar CO2 values with arterial CO2 tensions of blood drawn simultaneously. Twenty-two such comparisons reveal a mean deviation of -0.9 mm. Hg with a standard deviation of the mean of ± 1.8 mm. Hg. The limitations of the method are discussed. The method is compared with other methods for determining alveolar CO2 concentration. The practical value of the infrared method as a clinical guide to proper administration of artificial ventilation is demonstrated. © 1955.
