How do respirometers work

WebDec 27, 2024 · Respirometers are devices that measure these types of gas volume changes, and therefore provide information about the rate of cellular respiration. The ideal gas law, … 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., …
