Innovation for Personalized Weight Management

World’s 1st FDA cleared mobile metabolic rate analyzer


The Story Behind Breezing: A decade ago, a group of professors at Arizona State University (ASU) were requested by clients to invent a device for Resting Metabolic Rate (RMR) tests: accurate, mobile, and easy to operate. Breezing technology was then invented by our co-founders, including the award-winning ASU professor, Dr. Erica Forzani. Breezing accurately measures both oxygen and carbon dioxide, Resting Energy Expenditure (REE), i.e. Resting Metabolic Rate (RMR), and Respiratory Quotient (RQ). It is FDA cleared and its FDA’s cleared cleaning/disinfection protocol ensures safe use for patients. 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.

The benefits Breezing brings to healthcare providers, customers, and sports performance:

    1. Generating more revenue for healthcare providers and improving metabolic rate test efficiency
    2. Workflow optimization: with Breezing’s telemedicine ready feature, patients are scheduled for RMR tests at remote
      locations and the test results are exported or emailed to the healthcare providers
    3. Breezing’s flexible price options: affordable prices with flexible contract & pricing options
    4. Improving patient’s better adherence to healthier behavior

With innovative O2/COsensor integration, Breezing uses indirect calorimetry to measure O2 uptake and CO2 production in breath, REE (i.e. RMR) and RQ. Breezing provides accurate Gold Standard results and enables personalized health management programs. Clinical case studies in collaborations with the Mayo Clinic, the Pulmonary and Sleep Medicine Associates, the University of Arizona, and ASU have proven the use of Breezing leads to efficient personalized weight management.

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.
