  • Abstract
  • Look Inside

A technic for estimating VO2, VCO2 and RQ using a mixing chamber which has a flexible nature is described. The effects of this soft mixing chamber on an accuracy for metabolic rate measurement, and on the uses have been studied.

About the accuracy, the results indicate that the correlation with Douglas bag method is, y =0.997x-2.5 (r=0.995) in case of VO2 and y=1.00x-4.8 (r=0.997) in case of VCO2. About response time to changing of gas content, in same net volume chamber, the soft mixing chamber technic was much better than rigid one (≒1/4 response time in 95% response).
