[A new CO2 analyzer for monitoring of artificial ventilation (author's transl)].

A new CO2-Analyzer for continuous measurement of CO2 content during artificial respiration is described. Based on infra red absorption, this device may be used for measuring the carbon dioxide content of expiration in anaesthesia and intensive care. Carbon dioxide infrared absorption is affected by nitrous oxide. This side effect can be compensated by a single switch, if the sample contans N2O.
