Clinical Efficacy

Proven Clinical Results – Unique Study Design

  • Fully blinded with sham device (Placebo) as control arm
  • Eliminated Placebo Effect – Patients and Clinicians did not know treatment arm
  • Highest Level of Clinical Evidence – Level 1A (Double Blind with Placebo)
eo2 levels of evidence

Statistically Significant Outcomes in 12 Weeks

  • CDO leads to significantly higher rates of closure (2x to 4.6x)
  • CDO works better in more chronic, larger and weight-bearing wounds
  • CDO resulted in significantly faster time to closure (P<0.001)
  • Debridement significantly improves CDO outcomes

How Oxygen Works In Wound Healing

Increases Cell Metabolism & Energy
Continuous Pure Oxygen boosts vitality to support increased demand during healing 2-16

Faster Cell Growth & Wound Closure
  • Increased collagen deposition (faster repair) 17-29,59
  • Up to 70% faster endothelial gap closure rate
Rapid Pain Relief
  • Over half of patients experience >75% reduction within 4 days 28-32
  • Significant pain relief in a variety of wounds
Greater Wound Perfusion
Rate of angiogenesis proportional to oxygen concentration 33-40
Enhances Bodies Own Anti-Bacterial Capacity
Create Reactive Oxygen Species (i.e. Hydrogen Peroxide) 19,41-49,51

Better Strength & Appearance
  • Higher tensile strength (reduced recurrence) 50-61
  • Better collagen organization (reduced scarring)
