ABSTRACT:
Described herein is a patient interfacing system for sampling the inspired and expired gases of a patient and removing moisture from the sample. In one embodiment of the present invention, a patient link receives the gases from the patient's airway circuit and a vaporization section vaporizes condensed moisture in the sample. A separator section allows the vaporized moisture component of the sample to exit the patient interfacing system before the gas sample reaches the monitoring instrument. A filter may also be utilized to prevent condensed moisture, particulates and liquids from entering the monitoring instrument. Thus, the patient interfacing system of the present invention provides a reliable, cost effective and efficient means for delivering gas samples to a monitoring instrument which reduces or prevents water condensation inside the gas analysis portion of the monitoring instrument.
