Abstrakt: This article presents a study on calorimetry and respirometry in guinea pigs in hydrox and heliox at 10-60 atmosphere. The calorimeter was calibrated in 1-atm air by placing a small heater inside the instrument. A regulated direct current power supply was used to generate power of 1-15 W in the heater, with a random sequence of step changes in power input. When the calibration was completed, average power output measured by the calorimeter was within 2% of the power input to the heater, with a time-to-stable calorimeter reading of approximately 30 min. The calibration was repeated with the calorimeter placed in the dive chamber at 10, 20, 40, and 60 atmosphere heliox.
