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.

* RMR is calculated using the Weir equation and a constant RQ value of 0.85.
