Indirect calorimetry: technical aspects.
Journal of the American Dietetic Association, 1997Indirect calorimetry measures oxygen consumption and carbon dioxide production to calculate resting energy expenditure and respiratory quotient. The respiratory quotient can be determined from indirect calorimetry to determine substrate utilization and used to alter the patient's nutrition support regimen.

Simultaneous Direct and Indirect Calorimetry
1983Much of our knowledge of respiration rates is derived from measurements of oxygen uptake, one method of indirect calorimetry. The amount of oxygen consumed per unit time is often calculated from the decrease in partial pressure of oxygen in an enclosed air or water volume and then converted to equivalent heat production by using Ivlev’s [5 ...

Indirect calorimetry: applications in practice.
Respiratory care clinics of North America, 2007IC is the standard for determining energy expenditure in critically ill patients. The measured REE is an objective, patient-specific caloric reference that serves as the most accurate method of determining energy expenditure. Protocols addressing IC methodology are necessary to ensure technical accuracy and clinically useful results.
