Indirect Calorimetry: From Expired CO2 Production, Inspired O2 Consumption to Energy Equivalent

Priscila Giacomo Fassini, Jos&

Abstract

This paper emphasizes the methodology of data collection of indirect calorimetry, including establishment of steady state conditions and the standards in which the values are presented. It also aims to describe in details the calculations of VO2, VCO2, Resting Energy Expenditure (REE) and Respiratory Quotient (RQ). The trial is registered with ClinicalTrials.gov number NCT02072694.
