AB - The authors evaluated a 'state of the art' open hood type of indirect calorimeter (Deltatrac, Datex) to determine its stability and precision, and related these to in vivo measurements made with the same type of calorimeter. Three Deltatrac Metabolic Monitors were investigated at two centres over a period of twelve months by two methods of recovery: (i) gravimetric injection of a nitrogen/CO2 gas mix and (ii) ethanol burning using the manufacturers approved apparatus. Machine variation was compared with in vivo variation in measurements of oxygen uptake and carbon dioxide production at rest in healthy subjects. The studies re-emphasise that careful evaluation of commercially produced indirect calorimeters is essential before clinical measurements are made.
