ABSTRACT:
The humidity and/or temperature of a gas sample is monitored so that these system parameters can be accounted and/or actively monitored and controlled. In one embodiment, a gas analyzer system (10) includes an input flowline (12) for receiving a sample stream from a patient respiratory circuit via a patient input module (14), an analyzer instrument (16) for obtaining composition information regarding the gas sample, a humidity sensor module (18) containing a temperature sensor (40) and a humidity sensor (42), and a vacuum pump (22) for drawing the gas sample through the analyzer system (10). A processor (28) receives information from the analyzer instrument (16) and the humidity sensor module (18) and determines composition information regarding the gas sample based on such inputs. The analyzer system (10) thereby allows for improved composition measurements and for monitoring the humidity of the gas sample to stay within specifications or preferred operating ranges of certain analyzer instruments.
