KORR MetaCheck 7100, User Manual, Page: 7 / 48

Chapter 1: Introduction
1.1 Device Description
The MetaCheck™ Model 7100 is an indirect calorimeter. It determines
resting energy expenditure (REE) by measuring oxygen uptake. Resting
energy expenditure is the amount of calories that a patient will expend (burn)
in 24 hours of resting.
REE is calculated using the Weir equation with an assumed RQ=0.83. See “Weir,
J.B., New Methods for Calculating Metabolic Rate with Special Reference to
Protein Metabolism. J. Physiology, 1949 109: pages 1-9”
1.2 Intended Use
WARNING:
The MetaCheck™ is NOT a medical device.
It is not intended to be used for the diagnosis or treatment of disease.
For medical applications, customers should use the REEVUE Indirect Calorimeter from KORR™.
The REEVUE has clearance from the US Federal Food and Drug Administration (FDA)
to be marketed as a medical device.
The MetaCheck™ is intended for non-medical application to determine
energy expenditures in individuals. This is typically used to determine how
many calories the individual burns at rest.
The device determines resting energy expenditure (REE), also referred to as
resting metabolic rate (RMR) from a measurement of an individual’s oxygen
uptake.
The MetaCheck™ is typically used in applications to help individuals
determine the caloric requirements for them to lose, or maintain weight.
