REEVUE FAQ

How does REEVUE compare to hand-held indirect calorimeters?

The REEVUE is a traditional metabolic cart that has been tailored for Resting Energy Expenditure. By removing the features that accommodate ventilators and CO2, the cost has been reduced without sacrificing quality. Hand held devices are better suited for applications where clinical accuracy is not critical.

Even though hand held devices may be a less expensive initial investment, the cumulative cost of operation must be considered. REEVUE is the lowest cost indirect calorimeter to own, operate, and maintain. In part, this is because REEVUE does not limit the number of tests each unit will perform and because REEVUE uses standard respiratory fittings that don’t require you to buy proprietary disposables.

How does the REEVUE measure metabolic rate?

The human body consumes a fixed amount of oxygen per calorie burned. The REEVUE measures the amount of oxygen the patient's body is consuming. Based on the measured oxygen consumption rate, the REEVUE then calculates the Resting Energy Expenditure1 (REE). Or, in other words, exact amount of calories that person is burning.

What are the steps of a REEVUE test?

The REEVUE automatically calibrates itself, so there is no need to configure the unit prior to each test. First, ask the patient to relax in a seated or reclining position. The patient then breathes into a mask or mouthpiece for about 10 minutes. When the test is complete, the REEVUE prints a detailed report of the results. Perhaps the simplest indirect calorimeter ever built!

What is the difference between BMR and resting metabolic rate (RMR)?

BMR stands for Basal Metabolic Rate. BMR is a Resting Energy Expenditure test with a strict protocol to prepare the patient for the test. Therefore, the results from the REEVUE can be interpreted as BMR if the protocol is followed. The protocol has requirements regarding sleep, exercise, and fasting prior to the test, and temperature and lighting during the test.

What is the difference between REE and RMR?

These terms are essentially the same. REE stands for Resting Energy Expenditure. RMR stands for Resting Metabolic Rate. Both indicate the amount of energy a person burns at rest, and can be used interchangeably.

For what patients is the REEVUE contraindicated?

The REEVUE is not intended for use on ventilated patients, patients unable to tolerate being off supplemental oxygen for 20 minutes, or where an RQ is required. This was done to keep the product simple and affordable for caregivers that simply require an accurate Resting Energy Expenditure for determining caloric requirements.

What kind of patient connection does REEVUE require?

REEVUE can be used with a disposable mouthpiece or a disposable mask. It uses standard respiratory fittings to accommodate a variety of hoses and reusable masks.
