Web3. Determine the design of the indirect calorimeter (open- or closed-circuit). 4. Calibrate the indirect calorimeter on the day of measurement and more often if errors in measurement are suspected. 5. Ensure that the calibration gas mixture is relevant to the concentration of gas to be measured clinically. 6. WebClosed- and open-circuit spirometry are the two methods of indirect calorimetry. Closed circuit spirometry , where a participant inspires oxygen from a spirometer and expires back into the system (therefore a closed system) can be used to indirectly estimate MVO 2 , yet the equipment required becomes difficult to use during exercise (McArdle et ...
