Validated Breakthrough Technology

Metabolism is the single largest factor that dictates our daily caloric needs, varying from person to person and from time to time. The Academy of Nutrition and Dietetics recommends the tracking of metabolism with gold standard indirect calorimetry, which requires accurate measurement of a person’s consumed O2 and produced CO2 rates in breath. Breezing has developed a breakthrough sensing technology, that condenses the traditional O2 and CO2 sensors into a single stamp-sized sensor cartridge. The sensor cartridge is accurate and calibration free. The breath O2 and CO2 concentrations are combined with other pulmonary measurements (captured by Breezing’s patented device and processed by our proprietary algorithms) to achieve accurate RMR reading. Breezing technology has been extensively validated and reaches gold-standard benchmarks.

Clinical Studies

Breezing has been used in clinical studies and collaborations with leading institutes, including the Mayo Clinic, the Pulmonary and Sleep Medicine Associates, the University of Arizona, and Arizona State University.

CASE 1 – Breezing Accuracy Validation

Based on clinical studies and laboratory tests, Breezing’s accuracy is ~100% with 95% confidence intervals compared to the gold standard reference methods.  The findings of the clinical studies are summarized below.

  • Breezing accurately measures, O2, CO2 and REE, with results concurring with the Douglas Bag Method, with p < 0.0001
  • The study validates Breezing as an accurate tool for assessing metabolic parameters
  • Breezing helps healthcare providers assess patient’s metabolic health and develop personalized weight management programs with better clinical outcomes

CASE 2 – Effect of Mobile Indirect Calorimeter on Weight Management

In a published clinical study, patients treated with the Breezing device experienced twice as much weight loss, and 70% better adherence to healthy behaviors, with significant improvements in risk factors for Type II diabetes including HbA1C, cholesterol, and blood pressure.  The  clinical studies are summarized below.

  • Adding RMR to weight loss program using mobile Breezing resulted in greater weight loss; improved HDL cholesterol and greater adherence to health monitoring
  • It facilitated more comprehensive use of calorie counter app, including calorie intake tracking, activity tracking, weight tracking and sharing functions
  • Breezing provides tailored, precise, and accurate information to patients for health monitoring and improvement

CASE 3 – Metabolism Calculation vs. Actual Measurement

While calculations provide population average RMR, a comparison study between RMR calculated by the Mifflin St-Jeor predictive equation (MSJE) and RMR measured by the indirect calorimetry method with Breezing showed that the calculated values can under- and over-estimate the actual RMR by 950 and 660 kCal per day, respectively.  The following captures the Case 3 clinical studies findings:

  • No significant difference found between Mifflin-St Jeor Equation averages and average measurements from Breezing indicate the validity of mobile Breezing device
  • Breezing is a much easier method to use assess RMR and the measurement using Breezing should be practiced for clinical use
