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.

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.

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.

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 ...

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 ...

Indirect calorimetry in the mechanically ventilated patient
Critical Care Medicine, 1987We 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 ...

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 ...

Indirect calorimetry as point of care testing
Clinical Nutrition, 2019Determining 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.
