Energy 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 کاملEnergy Expenditure Measured by Indirect Calorimetry in Obesity
Mika Horie et al [2] demonstrated that obese women had higher total energy expenditure (TEE), compared with normal weight. However, this increase may be due to increased basal metabolic rate (BMR) due to higher fat-free mass (FFM) and energy demand during physical activity. However, Melo et al [3] found that obese individuals are economical, the metabolic point of view. Therefore, the energy ex...
متن کاملErratum to: Can calculation of energy expenditure based on CO2 measurements replace indirect calorimetry?
BACKGROUND Methods to calculate energy expenditure (EE) based on CO2 measurements (EEVCO2) have been proposed as a surrogate to indirect calorimetry. This study aimed at evaluating whether EEVCO2 could be considered as an alternative to EE measured by indirect calorimetry. METHODS Indirect calorimetry measurements conducted for clinical purposes on 278 mechanically ventilated ICU patients wer...
متن کاملComparison of indirect calorimetry, the Fick method, and prediction equations in estimating the energy requirements of critically ill patients.
BACKGROUND Accurate measurement of resting energy expenditure (REE) is helpful in determining the energy needs of critically ill patients requiring nutritional support. Currently, the most accurate clinical tool used to measure REE is indirect calorimetry, which is expensive, requires trained personnel, and has significant error at higher inspired oxygen concentrations. OBJECTIVE The purpose ...
متن کامل[Analysis of energy expenditure in adults with cystic fibrosis: comparison of indirect calorimetry and prediction equations].
OBJECTIVE Undernutrition, which implies an imbalance between energy intake and energy requirements, is common in patients with cystic fibrosis. The aim of this study was to compare resting energy expenditure determined by indirect calorimetry with that obtained with commonly used predictive equations in adults with cystic fibrosis and to assess the influence of clinical variables on the values ...
