Indirect calorimetry can be a useful tool to define nutritional status, determine nutritional requirements, and assess response to nutritional interventions. Measurements of oxygen consumption and carbon dioxide production may be used to determine cardiac output and work of breathing, and estimate the components of minute ventilation.

Summary Indirect calorimery is a method which allows the non-invasive measurement of enery expenditure and substrate utilization in humans. The procedure is described and the main equations to calculate energy expenditure and substrate utilization are presented.

Indirect calorimetry in cardiac patients
International Journal of Clinical Monitoring and Computing, 1988Nineteen patients following open heart surgery were studied for the influence of cardiac function on metabolism. Diminished cardiac index was associated with the following changes in metabolism: lowering of the energy expenditure, an increase in respiratory quotient and conversion from fat to carbohydrate metabolism.

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 ...

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)
