Oxygen Therapy: Transcutaneous
Transcutaneous oxygen therapy is a non-invasive method of providing oxygen to the wound bed to facilitate healing. Devices and dressings that provide concentrated oxygen have demonstrated efficacy in providing a local environment conducive to wound healing.
Transcutaneous oxygen therapy is a non-invasive method of providing oxygen to the wound bed to facilitate healing. Oxygen is of paramount importance to collagen formation, granulation, angiogenesis and epithelialization, and also plays an important role in controlling bacteria. Devices and dressings that provide concentrated oxygen have demonstrated efficacy in providing a local environment conducive to wound healing that is particularly useful in healing chronic wounds.
Transcutaneous oxygen therapy devices feature the following general performance properties and attributes:
- Delivers continuous oxygen to the wound bed
- Non-invasive
- Portable
Transcutaneous oxygen therapy is indicated to provide transdermal sustained oxygen therapy to treat the following: skin ulcerations due to diabetes, venous stasis, post-surgical infections and gangrenous lesions; pressure ulcers; amputations and infected stumps; skin grafts; burns and frostbite.
Contraindicated for use on wounds with inadequate perfusion to support healing and on ulcers due to acute thrombophlebitis or Raynaud’s disease, wounds completely covered with eschar, wounds with fistulae or deep sinus tracts where the end cannot be probed, wounds covered with petroleum-based dressings and on non-compliant patients.
The following general warnings apply to transcutaneous oxygen therapy devices. Always refer to manufacturer information for Warnings and Precautions for a specific product.
Do not use petroleum-based products in the moist wound bed, as this will prevent oxygen from diffusing into the wound tissue.
Sterile dressings and cannulas are intended for single use only.
Do not use after expiration date.
Appropriate supportive measures should be taken where necessary (e.g. use of graduated compression in the management of venous leg ulcers, systemic antibiotics and frequent monitoring in the treatment of wound infection, control of blood glucose for diabetic ulcers, etc.).
