World’s 1st mobile metabolic rate analyzer


Breezing’s metabolism technology was invented by the award winning professors and it’s devices were designed by a team led by Mayo Clinic fellow, chief clinic officer, Dr. Forzani for academic, sports performance, and clinical applications with FDA clearance. With the much improved design from the first generation – Trackers, Breezing has been validated against the Gold Standards by independent 3rd parties. Breezing products are being utilized by Mayo Clinic, Harvard Medical School, Northwestern Univ. Sports Program, Cincinnati Children’s Hospital Medical Center, and many others worldwide.

Whether you’re looking for a RMR Testing Machine, athletic performance testing equipment, respiratory quotient device, metabolism-tracking mask, resting metabolic rate analyzer or even a metabolic rate analysis system, we’ve got you covered.

The breakthrough sensor technology uses a single stamp-sized sensor cartridge, which accurately measures both oxygen (O2) and carbon dioxide (CO) in breath and Resting Energy Expenditure (REE), using indirect calorimetry. Breezing’s FDA’s cleared cleaning/disinfection protocol ensures safe use.

Why Breezing?

    1. Cutting edge O2& COsensor technology (O2& COaccuracy < 1%)
    2. Accurate Resting Metabolic Rate (RMR), respiratory quotient results
    3. Competitive device cost, low recurring cost
    4. No manual calibration, no maintenance needed
    5. Easy & comfortable to use with no nose clips
    6. Remote or onsite assessment
    7. HIPAA-compliant apps
    8. FDA 510k cleared (Breezing MedTM)

REE/RMR assessments using indirect calorimetry is more accurate than REE predictive equations Click this link to review – Paper published in the Global Journal of Obesity,

No More REE/RMR/RQ Guesswork

While calculations provide population average RMR/REE, clinical studies have indicated calculated RMR/REE using metabolic equation for a patient is misleading due to errors as much as 1000 kcal per day. With Breezing, accurate REE/RMR/RQ measurement, by measuring both (O2/CO in breath with low test costs, is possible.

Breezing: Science, Technology, Device, & Apps

Breezing precisely measures metabolic data (REE/RMR and RQ) from a patient’s breath using a disposable, single-use O2/CO sensor cartridge, syncing the data through a mobile app.

1. The Science

Breezing is based on proven science and clinically validated technology.

2. The Sensor Technology

Breezing’s proprietary technology combines traditional O2 and CO2 sensors into a single sensor cartridge, offering precise RMR measurement without the need for manual calibration.

3. The Device

Using Breezing is simple: just insert the sensor cartridge, wear the device, and breathe for 10 mins. No lengthy setup and manual calibration needed.

4. The Mobile App

The app guides the measurement, displaying the results, history, and progress of each patient.
