AB -  sample line is difficult and eventually results in accumulation of large water droplets. These droplets disrupt the flow rate of the sample and eventually are deposited in the gas analyzers. The predominant effect of water vapor on respiratory gas analysis is the partial-pressure displacement of the analyzed gas by the water vapor. For example, if a water vapor saturated sample at 37OC (47 Torr PH~o) containing 15% oxygen is dried, the water removed increases the oxygen concentration to 16%. This increase in 02 concentration means a 17% increase in the calculated oxygen consumption, over that for no correction due to water vapors (4). Another effect is the interference of the water vapor with the physical phenomena in the gas sensors, as for example, the infrared CO2 gas analyzer exhibits a slight positive sensitivity caused by water vapor (3) and the oxygen analyzers using the heated electrochemical cells increase their response time constant when water condenses and evaporates within the analysis system (6). To dry the expired gas sample before it reaches the analyzers, we designed a water condensation method similar to that described by Auchincloss et al. (l), but with some modifications that enabled us to extend our
