For the purpose of measuring the concentration of one or more given components of the breathing gas of a patient there is removed a small part of the breathing gas at a location immediately in front of the mouth of the patient. The withdrawn gas is passed to a measuring instrument sensitive to the component or components of interest through a line which comprises, at least in part, a thin tube of a fluorosulfonyl polymer, and the outer surface of which is in free contact with the ambient air. In this way, the temperature and relative humidity of the brea...
A method for measuring the concentration of at least one given component in a breathing gas passing through a breathing-gas line connected to the air passages of a patient, comprising the steps of withdrawing continuously a small part of the gas flow passing through said breathing-gas line, bringing the relative humidity and temperature of said withdrawn gas into substantial agreement with the relative humidity and temperature of the ambient air, and subsequently supplying said withdrawn gas to a measuring instrument sensitive to the concentration of sai...
