Welcome to BiologyDiscussion! 7 0 obj Careers. In the direct method for the measurement of energy expenditure for individuals, the Atwater calorimeter is used which consists of a chamber in which a person could live and work for several days allowing at the same time the measurement of his total output of heat.

Indirect calorimetry (IC) is the gold standard for measuring resting energy expenditure (REE), this study aimed to compare the results of REE estimated by different methods with those obtained by IC for patients with pulmonary hypertension. The DEE, as observed in a respiration chamber over 24 h has been evaluated in different ways: (1) as the difference in 24-h energy expenditure between a day in the fed state and a day in the fasted state, (2) . activities throughout the 24 hours. instrumentation.
