Open-circuit respirometry: a historical review of portable gas analysis systems.
The European Journal of Applied Physiology is publishing a series of reviews examining some historical insights into the measurement of whole body metabolic rate.
This review is focusing on portable research based devices designed to estimate metabolic rates during typically steady-state conditions, and areas that contribute to measurement errors or other reliability and usability issues.
Over more than 110 years of development in portable gas analysis systems, we have seen many significant advances in the estimation of metabolic rate under steady-state conditions.
When analyzing the new COSMED K5, this reviews focuses on IntelliMET and the possibility to perform gas sampling either breath-by-breath or with dynamic mixing chamber. "The option of dual measurement allows users to undertake more conventional steady-state metabolic measurements via the dynamic mixing chamber, or to examine kinetics during transients, permitting greater versatility by allowing users to mitigate criticisms of either sampling method."
