What is Med Gem?

What is Med Gem?

The MedGem is an FDA-approved, hand-held indirect calorimeter. Your body combines food (carbohydrates, fats, and proteins) with oxygen to produce energy. The MedGem measures the amount of oxygen the body consumes (VO2) and determines resting metabolic rate (RMR) in calories/day.

What is meant by indirect calorimetry?

Indirect calorimetry (IC) assesses the amount of heat generated indirectly according to the amount and pattern of substrate used and byproducts generated. Specifically, EE can be calculated by measuring the amount of oxygen used (VO2), and carbon dioxide released (VCO2) by the body.

What is indirect calorimetry used for?

Indirect calorimetry is the method by which measurements of respiratory gas exchange (oxygen consumption, V O 2 and carbon dioxide production, V CO 2 ) are used to estimate the type and amount of substrate oxidized and the amount of energy produced by biological oxidation.

What are the two methods of indirect calorimetry?

Indirect calorimetry systems estimate respiratory gas exchange as a surrogate for substrates consumed and produced during metabolism. This is done by one of 4 methods: confinement, closed-circuit, total collection, and open-circuit approaches.

How much does a MedGem cost?

The MedGem System Kit is the best long-term system, because it has the lowest per-use cost. It is designed for people who want to own their system and not lease. Additional 21-packs of Mouthpiece Filters and Nose Clips are $299. When you purchase two 21-packs, you get one 21-pack for FREE.

What do you mean by calorimeter?

: an apparatus for measuring quantities of absorbed or emitted heat or for determining specific heats.

What is the principle of indirect calorimetry?

Indirect calorimetry is based on the premise that gas volumes and concentrations exchanged at the mouth reflect cellular metabolic activity. By measuring the difference between inspired and expired levels of oxygen and carbon dioxide, determinants of VO2 and VCO2 can be obtained (Table 3).

How does an indirect calorimetry work?

Indirect calorimetry calculates heat that living organisms produce by measuring either their production of carbon dioxide and nitrogen waste (frequently ammonia in aquatic organisms, or urea in terrestrial ones), or from their consumption of oxygen.

Who uses indirect calorimetry?

Indirect calorimetry (IC) is considered the gold standard to measure caloric needs in critically ill patients at bedside, and its use has been strongly recommended by the recent European Society for Clinical Nutrition and Metabolism (ESPEN) and American Society for Parenteral and Enteral Nutrition (ASPEN) guidelines [1 …

What is the difference between direct and indirect calorimetry?

Direct calorimetry measures the heat output by the subject, through direct observation inside a calorimeter. Indirect calorimetry measure heat by using the variable of O2 consumption and manufactured CO2. Indirect calorimetry gives a more feasible and accurate measure of heat or energy, compared to direct calorimetry.

Why is indirect calorimetry the gold standard?

Indirect calorimetry (IC) estimates resting energy expenditure from inspired oxygen and expired carbon dioxide and has been described as the “gold standard” for determining calorie expenditure for critically ill patients.

How accurate is BodyGem?

In several studies the BodyGem has repeatedly demonstrated an accuracy of 1-3% when compared to other standard reference systems. The BodyGem’s portability makes measuring metabolism possible for most individuals and professionals.

How does the medgem indirect calorimeter device work?

MedGem FDA-Approved Indirect Calorimeter The MedGem indirect calorimetry device is a clinically-validated and FDA 510K-cleared, class II, medical device for measurement of patient resting metabolic rate (RMR). The MedGem is an easy-to-use, handheld device that accurately measures oxygen consumption (VO2) to determine resting metabolic rate (RMR)*.

Which is the best definition of indirect calorimetry?

indirect calorimetry measurement of the amount of heat produced by a subject by determination of the amount of oxygen consumed and the amount of carbon dioxide eliminated. Miller-Keane Encyclopedia and Dictionary of Medicine, Nursing, and Allied Health, Seventh Edition. © 2003 by Saunders, an imprint of Elsevier, Inc.

How much does indirect calorimetry cost in Colorado?

Many payers including Medicare, Medicaid, and private insurance companies reimburse Indirect Calorimetry for patients with pulmonary, cardiovascular, and metabolic disease. The Medicare reimbursement rate average is $63 in Colorado. Rates range from $60 – $80 in total (Pt. Co-pay + reimbursement).

What do you need to know about medgem analyzer?
