Indirect calorimetry in critical care.
In critical care, particular attention is paid to disorders which lead to cerebral dysfunction. Hypoxia is the most common example and considerable effort is devoted to avoiding this problem. If the brain is deprived of fuel, as in hypoglycaemia, the outcome is similar yet far less attention is paid to maintaining an adequate and appropriate long-term fuel supply. Indirect calorimetry has been ...
متن کاملChallenges of indirect calorimetry in mice.
TO THE EDITOR: the recent paper by Longo et al. (5) provides an excellent description of the challenges of performing indirect calorimetry in mice. Mice that gain weight or are weight stable in their home cages often lose weight during the indirect calorimetry measurements, indicating that the procedure alters the usual behavior of the animals. To tackle this difficulty, the authors proposed a ...
متن کاملWhat does indirect calorimetry really tell us?
Accurate and sensitive assessments of energy expenditure (EE) in mice changes in the balance of gut microbial species could differentially are essential given their importance to research on the molecular mechanisms of energy homeostasis [1]. EE phenotyping in mice is widely available using state-of-the-art equipment in many laboratories, including those in regional centers in the United States...
متن کاملEnergy expenditure in critically ill patients estimated by population-based equations, indirect calorimetry and CO2-based indirect calorimetry
BACKGROUND Indirect calorimetry (IC) is the reference method for measurement of energy expenditure (EE) in mechanically ventilated critically ill patients. When IC is unavailable, EE can be calculated by predictive equations or by VCO2-based calorimetry. This study compares the bias, quality and accuracy of these methods. METHODS EE was determined by IC over a 30-min period in patients from a...
متن کاملCumulative energy imbalance in the pediatric intensive care unit: role of targeted indirect calorimetry.
INTRODUCTION Failure to accurately estimate energy requirements may result in underfeeding or overfeeding. In this study, a dedicated multidisciplinary nutrition team measured energy expenditure in critically ill children. METHODS Steady-state indirect calorimetry was used to obtain measured resting energy expenditure, which was compared with equation-estimated energy expenditure and the tota...
