Innovation for Personalized Weight Management

  the world’s first FDA cleared mobile metabolic

rate analyzer

It accurately measures both oxygen and carbon dioxide, Resting Energy Expenditure (REE), i.e. Resting Metabolic Rate (RMR), and Respiratory Quotient (RQ). Breezing products are being utilized by Mayo Clinic, Northwestern Univ., Cincinnati Children’s Hospital Medical Center and many others worldwide.

Awards Received: Top 10 winners in 2018 ACA Innovation Challenge, Finalist in 2020 R&D 100 Awards in science and technology.

    1. Generating more revenue for healthcare providers and improving RMR test efficiency
    2. High accuracy, validated against the standards (O2& COaccuracy < 1%)
    3. Competitive device cost, low recurring cost
    4. No manual calibration, maintenance required
    5. Easy and comfortable to use with no nose clips
    6. Remote or onsite assessment
    7. HIPAA-compliant apps
    8. FDA 510k cleared (Breezing MedTM)
    9. FDA cleared cleaning/disinfection protocol to ensure safe use



REE/RMR assessments using indirect calorimetry is more accurate than REE predictive equations

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. Click the link: REQUEST DEMO to experience Breezing. For assistance, click the link: CONTACT US.

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.
