Clinical Efficacy & Success Rates
Clinical efficacy data represents the cornerstone of HBOT’s medical acceptance and continued growth. Success rates vary significantly by condition, with emergency applications showing the highest efficacy and emerging applications demonstrating promising but variable outcomes. These statistics reflect real-world clinical outcomes from peer-reviewed studies and clinical registries.81.8% Overall success or improvement rate across 181 patients in comprehensive study
HBOT’s clinical efficacy stems from its fundamental mechanism of dramatically increasing oxygen delivery to tissues. At 2-3 atmospheres of pressure, blood plasma can carry significantly more dissolved oxygen, reaching tissues with compromised blood supply. This enhanced oxygenation promotes wound healing, reduces inflammation, stimulates angiogenesis, and supports cellular repair mechanisms across diverse pathological conditions. 90%+ Decompression Sickness Success
