Overview

In a new study published in Wounds (May 2024), Dr. Windy Cole and Dr. Emma Woodmansey explored the effectiveness of Continuous Topical Oxygen Therapy (cTOT) in treating chronic nonhealing wounds. The study, titled “Monitoring the Effect of Continuous Topical Oxygen Therapy With Near-Infrared Spectroscopy: A Pilot Case Series in Wound Healing”, offers compelling evidence of increased tissue oxygen saturation, reduction in wound size, and healing.

Key Findings

This pilot case series involved five patients with non-healing wounds, treated over five weeks. The results were promising:

  • Significant Reduction in Wound Area: All patients showed significant reductions in wound area over the 5-week study period.
  • Improved Tissue Oxygenation: Near-infrared spectroscopy (NIRS) revealed increased tissue oxygenation in all patients, correlating with wound healing progress.
  • Healing: Three of five patients reached complete wound closure within the 5-week study period. The other two reached complete healing at weeks 9 and 11.

Study Insights

The study highlighted the critical role of oxygen in wound healing, especially in chronic conditions where tissue oxygen levels are compromised. By using NIRS, the researchers could objectively measure and track tissue oxygenation, providing valuable insights into the efficacy of cTOT.

Why Continuous Topical Oxygen Therapy?

cTOT delivers continuous oxygen directly to the wound bed, enhancing the healing environment. This innovative approach supports:

  • Faster Healing: Accelerates the wound healing process by improving tissue oxygenation.
  • Noninvasive Treatment: Offers a noninvasive alternative to traditional methods, making it suitable for a wide range of patients.
  • Convenient Use: The wearable, easy-to-use device allows patients to maintain their daily activities uninterrupted.
