  author={J Wells and N S Fuller},
  journal={European Journal of Clinical Nutrition},
Objective: To determine within-machine and between-machine precision (reproducibility) and accuracy, of the Deltatrac Mk 1 Metabolic Monitor.Design: Within-machine and between-machine comparison for gas exchange (VO2 and VCO2), respiratory quotient (RQ) and energy expenditure (EE).Subjects: 3 Deltatrac Mk 1 Metabolic Monitors.Methods: Within-machine and between-machine reproducibility were assessed by five successive 10 min gas infusion tests in each machine. Accuracy was assessed by measuring… CONTINUE READING
