Reduces dyspnea and increases exercise endurance for patients with COPD

Breathe Technologies’ wearable and open ventilation* decreases work of breathing (WOB), respiratory muscle activation, and dyspnea, allowing for improved exercise tolerance and 6-minute walk tests (6MWT) compared to traditional oxygen therapy.1-6

  • reduction in healthcare costs and healthcare utilization such as inpatient admissions and mechanical ventilation days7
  • reduction in patient-reported CAT and mMRC scores2
  • reduction in WOB1
  • 46% reduction in accessory respiratory muscle activation3
  • 28% reduction in Borg Dyspnea Scale3
  • 54% increase in exercise endurance from 11.4 to 17.5 minutes (P < .001)3
  • 34 to 73 m improvement in 6MWT distance4,5
  • 85% improvement in ability to perform activities of daily living6

Impact of improving mobility and activity levels

  • Activity for 2 hours a week reduces hospital admissions and respiratory mortality by 30% to 40%, according to a 20-year follow-up study of 2,386 subjects with COPD8
  • Outdoor activity increases 4-year survival 35% versus 15% for oxygen-dependent patients9
  • Physical activity is the best predictor of all-cause mortality in COPD patients; for every 0.14 decrease in physical activity level (PAL), the relative risk of death is more than doubled10
