Respirometer definition of respirometer by Medical dictionary

The metabolism of an animal is estimated by determining rates of carbon dioxide production (VCO2) and oxygen consumption (VO2) of individual animals, either in a closed or an open-circuit respirometry system. Two measures are typically obtained: standard (SMR) or basal metabolic rate (BMR) and maximal rate (VO2max). SMR is measured while the animal is at rest (but not asleep) under specific laboratory (temperature, hydration) and subject-specific conditions (e.g., … Web1 Respirometer: CLEAPSS Laboratory Handbook section 15.10 includes details of how to construct your own respirometers if you do not wish to purchase ready-made kit.
