Korr ReeVue Indirect Calorimeter
The Korr ReeVue Indirect Calorimeter measures the oxygen that the body consumes. Using this measurement it calculates a patient’s Resting Energy Expenditure (REE), commonly referred to as a Resting Metabolic Rate (RMR). Physicians can screen for abnormally low metabolic rates and pinpoint the precise caloric intake required for weight loss, maintenance, or weight gain. Applications include nutritional assessments required to treat obesity as well as obesity related diseases such as metabolic syndrome, sleep disorders, diabetes, and thyroid disorders. Under strict laboratory protocol, the ReeVue can be used to measure basal metabolic rate (BMR).

Direct Oxygen Measurement
ReeVue by KORR directly measures the concentration of oxygen breathed out by each patient. The patient merely breathes through a simple mouthpiece as all the exhaled air is collected and analyzed. Because there is a direct correlation between oxygen consumed and calories burned (4.813 calories for every milliliter of oxygen consumed), an accurate measurement of oxygen consumption is an effective measurement of calorie consumption.
Mixing chamber Technology
A mixing chamber is considered the “Gold Standard” for Indirect Calorimetry (more commonly referred to as a Metabolic Measurement.) In the past, this system has been complicated and expensive, making it only practical for ICU’s and research departments. KORR advancements in technology make this method feasible for the typical practitioner.
Adjustments for barometric pressure, temperature, and humidity are key to an accurate VO2 measurement. The Korr ReeVue Indirect Calorimeter measures these parameters during each routine calibration cycle, then automatically compensates to standard (STPD) conditions.
Other Indirect Calorimeters require the patient to draw both their inhalation and exhalation through the measurement device located at the patient’s mouth. The air they breathe in will pass through the same mechanism as countless patients before them. KORR uses a one-way valve in the disposable MetaBreather mouthpiece. This draws in fresh room air with each inspiratory breath and eliminates concerns about cross contamination. The disposable is thrown away and there is no need to clean equipment between each patient.
The Korr ReeVue Indirect Calorimeter has a simple user interface that assists the operator from start to finish. No training or certification is required. It does not require a computer or software, and even the printer is optional. Everything you need is at your fingertips!
