Abstract
A calorimeter configured to determine a metabolic rate of an individual based on measurements of the individual's respiration. The calorimeter includes an inlet, a flow sensor, a mixing chamber, a gas sensor, and a calibrator. Each of these elements is located along a flow path through the calorimeter. The calibrator of the calorimeter includes a fan that is configured to force calibration gases, such as room air, through or past the gas sensor. A cardiac rate monitor is associated with a processor of the calorimeter. The processor is configured to substantially simultaneously determine and establish a relationship between the cardiac rate of the individual and the measured respiratory parameters or the metabolic rate of the individual. Data representative of this relationship may be communicated to a processor or memory of a portable calorimeter to be subsequently used by the individual. The portable calorimeter, which can be worn by the individual, includes a cardiac rate monitor that measures the cardiac rate of the individual and communicates data representative of the individual's cardiac rate to the processor, which then determines the metabolic rate of the individual based on relationship data obtained from the respiratory-based calorimeter. Methods of calibrating and using the calorimeters are also disclosed.
