The use of indirect calorimetry to measure the heat production of men and animals has increased rapidly since the pioneering work of Lavoisier. Measurement of the consumption of oxygen and production of carbon dioxide are the basis for the measurement of heat production.

Applications of Indirect Calorimetry
Critical Care Nursing Clinics of North America, 2000Indirect calorimetry should be considered a useful and practical adjunctive technology that can assist in the assessment and management of critically ill patients. Examples of applications of indirect calorimetry include nutritional assessments of metabolic status, evaluation of the oxygen cost of breathing during mechanical ventilatory support, and ...

Indirect calorimetry: methodological and interpretative problems
American Journal of Physiology-Endocrinology and Metabolism, 1990The technique of indirect calorimetry is now widely used to examine rates of energy production and substrate oxidation in humans. Although the basic principles of indirect calorimetry are well established, it is important to recognize that there are several potential pitfalls in the methodology and data interpretation that must be appreciated to ...

AACN Clinical Issues: Advanced Practice in Acute and Critical Care, 2003
Physiologic monitoring of the patient's metabolic response to illness and nutritional needs has been available for many decades. Traditional methods for estimating and intermittently assessing the patient's metabolic status provide incomplete and often misleading information. The measurement oxygen consumption (VO2) and carbon dioxide production (VCO2)

Circulatory Indirect Calorimetry in the Critically III
Journal of Parenteral and Enteral Nutrition, 1991Circulatory indirect calorimetry (CIC) is a potentially useful method to assess the energy requirements of critically ill patients. Unlike respiratory indirect calorimetry (RIC), which measures oxygen utilization from inhaled and exhaled gases, CIC measures oxygen utilization from arterial and mixed venous blood.

Microprocessors in indirect calorimetry
Journal of Microcomputer Applications, 1984Abstract Indirect calorimetry calculates energy expenditure and respiratory quotient from oxygen consumption and carbon dioxide production. Continuous flow ventilated hood systems allow prolonged measurements to be made. The incorporation of a microprocessor enables immediate computation and graphic display during a calorimetry run, processing of ...

Automated, eight-cage indirect calorimetry in rats
Nutrition, 1998We have constructed an automated, eight-cage indirect calorimeter (AIC) for the measurement of energy expenditure in rats. We compared the measurements of resting energy expenditure (REE) in rats during a 30-h fast obtained with the AIC with those obtained with a manual indirect calorimetry (MIC) system.
