Why Choose ReeVue®?

  • Measures Resting Energy Expenditure (REE/RMR)
  • Determines caloric requirements
  • CPT code #94690
  • FDA cleared
  • Can be operated by any office staff
  • Unique printout to aid teaching

The REEVUE® 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).  To download a ReeVue product brochure, click here.

ReeVue® Features

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.  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.
ReeVue® has been independently validated at the University of Southern California and Georgia State University. To view those results, click here.

Clean

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.

Self Calibrating

Adjustments for barometric pressure, temperature, and humidity are key to an accurate VO2 measurement. The ReeVue measures these parameters during each routine calibration cycle, then automatically compensates to standard (STPD) conditions.

Simple

The ReeVue® 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!

Reimbursable

Indirect calorimetry is CPT code #94690 and is covered by Medicare and most insurance providers.  For more information regarding the procedure code, diagnosis codes or Medicare coverage, click below.

Frequently Asked Questions

Open all Close all
  • How long does this test take?

    The test takes approximately 10 minutes.

  • Can the disposable hose be used more than once?

    The disposable hose (the METABREATHER™) is for single patient use only. It cannot be effectively cleaned between patients and the valves within the mouthpiece will not maintain accuracy through multiple tests.

  • What kind of warranty do the products come with?

    All KORR™ products come with a full 2 year warranty which includes all parts and labor. Routine maintenance is not covered under warranty. A renewable warranty is available to purchase for subsequent years.

  • How many tests can you do on the machine?

    The machine will perform an unlimited number of tests.

  • Is certification required to operate the machine?

    No certification is required. With its simple one button operation, anyone can be trained to operate the machine in just minutes.

  • What happens if the machine needs any maintenance?

    All maintenance and repairs are performed at KORR™ Medical’s Service Center in Salt Lake City, Utah. Currently locations include Salt Lake City Utah USA, Sydney Australia, and Athens Greece. Every 20 to 24 months the machine requires oxygen sensor replacement and re-calibration.

CPT codes must be accompanied by an appropriate diagnosis code (ICD-10).

Weight Management:

Medicare Nationally Covered Indications currently reads: “services performed in connection with the treatment of obesity are covered by Medicare when such services are an integral and necessary part of a course of treatment for diseases such as hypothyroidism, Cushing’s disease, hypothalamic lesions, cardiovascular diseases, respiratory diseases, diabetes, and hypertension.”

The AMA* cites that diagnoses codes supporting the medical necessity of Indirect Calorimetry include:

  • E88.81  Metabolic Syndrome
  • E88.9  Metabolic Disorder, Unspecified
  • G47.00 – G47.9  Sleep Disturbances
  • R06.02  Shortness of Breath
