  • Page 7: Chapter 1: Introduction

    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.
  • Page 8 Theory of Operation 1.3.1 Metabolic Testing Metabolism is the process of converting food into heat or energy. The rate and efficiency with which the body converts food to energy is referred to as the metabolic rate. The most direct method of measuring metabolic rate is to directly measure the amount of heat produced by the body.
  • Page 9 1.3.3 Calorie Calculation The number of calories expended for a given amount of oxygen consumed. The exact relationship between calories consumed and oxygen consumption is also affected by the amount of carbon dioxide produced by the body as well as oxygen consumed. However, the error that occurs by not considering carbon dioxide is never larger than 1% and is usually less than 0.5% during a resting metabolic test.
