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 ...

Bailliere's clinical endocrinology and metabolism, 1988
Indirect calorimetry is a method which allows the non-invasive measurement of energy expenditure and substrate utilization in humans. The procedure is described and the main equations to calculate energy expenditure and substrate utilization are presented.

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)

Indirect Calorimetry in Chair‐Adapted Primates
Journal of Parenteral and Enteral Nutrition, 1986This paper describes the construction of an indirect calorimeter for measurement of respiratory gas exchange in the chaired primate. Preliminary determinations of energy expenditure and respiratory quotient in five animals under a variety of dietary conditions suggest that this system will prove useful in the laboratory study of primate nutrition ...

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.

Indirect calorimetry in the ICU
2016Abstract Critically-ill patients have unpredictable and dynamic metabolic demands that are difficult to predict and quantify. Combined with the high incidence of pre-existing or development of malnutrition in the ICU, these metabolic demands have deleterious effects on outcomes when patients are provided with inadequate or inappropriate ...
