Applications of Indirect Calorimetry

Critical Care Nursing Clinics of North America, 2000
Indirect 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 in cardiac patients

International Journal of Clinical Monitoring and Computing, 1988
Nineteen 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.

7 Indirect calorimetry

Baillière's Clinical Endocrinology and Metabolism, 1987
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 the ICU

2016
Abstract 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 ...

Circulatory Indirect Calorimetry in the Critically III

Journal of Parenteral and Enteral Nutrition, 1991
Circulatory 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.

Indirect calorimetry in the mechanically ventilated patient

Critical Care Medicine, 1987
We used indirect calorimetry to measure oxygen consumption (VO2) and carbon dioxide production in 29 mechanically ventilated patients. These data were compared to VO2 measured simultaneously by a standard thermodilution technique. A good correlation was demonstrated between the methods, but VO2 measured by indirect calorimetry was 15% higher than VO2 ...

Indirect Calorimetry in Chair‐Adapted Primates

Journal of Parenteral and Enteral Nutrition, 1986
This 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 ...

Indirect calorimetry as point of care testing

Clinical Nutrition, 2019
Determining energy requirement is a fundamental of nutrition support. Indirect calorimetry (IC) has been long recognized as the gold standard for assessing basal or resting energy expenditure (REE). The measurement of REE is recommended particularly in the situation where adjustment of energy provision is critical.
