The MedGem indirect calorimetry device is a clinically-validated and FDA 510K-cleared, class II, medical device for measurement of patient resting metabolic rate (RMR).
The MedGem is an easy-to-use, handheld device that accurately measures oxygen consumption (VO2) to determine resting metabolic rate (RMR)*.
Measurements made with the MedGem are easy to administer and provide accurate results in only a few minutes.
Microlife’s WatchWT MedGem device is being used to assess metabolic changes in The Biggest Loser™ contestants. “We chose to use the MedGem device based on its accuracy in comparison to other indirect calorimeters.” said Dr. Robert Huizenga, Associate Professor of Clinical Medicine at UCLA and Medical Advisor to The Biggest Loser
What Do the Experts Say About the MedGem Device?
“The MedGem may be a useful clinical tool when the Delta-Trac indirect calorimeter is not available….5 predictive equations compared to the MedGem measurement found none of the equations had acceptable bias and precision among overweight and obese adults.” Ziegler et al. 2010
“The portable MedGem may assist research dietitians in determining energy needs of racially diverse populations of middle-aged overweight and obese women.” Spears et al. 2009
“The use of the MedGem may provide clinicians a diagnostic tool for tailoring a nutrition message specific to each client.” McDoniel et al. 2008
“Cardiac output determinations made with the MedGem’s measurements of oxygen uptake are clinically acceptable.” Shepherd et al. 2007
“The MedGem hand-held indirect calorimeter has potential application in clinical evaluations in which typical metabolic carts or other standard methods are not practical.” Fields et al. 2006
The MedGem can be used to accurately measure oxygen consumption and RMR in capacities where a traditional metabolic cart would not be practical or cost-effective.” Stewart et al. 2005
“The MedGem provides a quick and convenient estimate of RMR in children that is accurate and reliable, and should facilitate the process of pediatric weight management counseling.”Nieman et al. 2005
