This study proves that accurate measurement of the REE in underweight anorexia nervosa patients is clinically useful, overcoming the limits of predictive formulas. Several studies showed that REE is low in underweight patients with Anorexia Nervosa, this is mainly due to the loss of lean body mass, a major determinant of REE, and to a lesser extent, to the effect of several neuroendocrine changes. The...
A new study examines the role of indirect calorimetry in ventilated ICU patients as an important clinical tool compared to daily estimated energy requirements predicted by the Schofield equation. Twenty four indirect calorimetry tests were conducted during routine practice using the COSMED Quark RMR. The study conclusion was that "the Schofield equation significantly overestimated energy requirements...
The COSMED Quark RMR with the ICU option has been recently assessed to be a suitable indirect calorimeter to be coupled with a mechanical ventilator in an intensive care unit setting. The study aimed at measuring the influence of the ventilatory settings on the parameters measured by the Quark RMR metabolic monitor. The energy expenditure of 10 mechanically ventilated cardiosurgical patients was...
A validation study of Quark RMR by CRNHR was published on the 6th issue of the European Journal of Clinical Nutrition and Metabolism. The objectives of the study by the Centre de Recherche en Nutrition Humaine Rhône-Alpes were to validate accuracy and reliability of COSMED QUARK RMR indirect calorimeter versus the DELTATRAC II™, a well-established reference system, which is no longer available,...
In this study the measurements of two different indirect calorimeters from COSMED (Fitmate and Quark RMR) were correlated and analysed for better adequacy. The aim of this study was to check measurements of two indirect calorimeters on obese women and then comparing the results with predictive formulas (the popular Harris Benedict Equation). Two COSMED indirect calorimeter systems were chosen:...
