Modification of Otis-McKerrow Valve for Measurement of Respiratory Water Loss,
Abstract
An apparatus is described that allows a continuous measurement of inspired and expired gas dew-point temperature for the calculation of water loss during ventilation (Eres). A rapid response dew-point temperature measurement method based on a small Peltier module. The compact structure with near zero system dead space minimizes potential errors inherent in many techniques used to measure Eres. A simple design and rugged construction permit the incorporation of the apparatus into many manual or personal computer controlled oxygen consumption systems. Collection of data may be done in a variety of ambient temperatures, altitudes and activity levels. There is also the potential for creating a portable system for field use.
