KEY TAKEAWAYS:
Vaporous hyperoxia therapy (VHT) is an FDA-cleared, pain-free treatment that pairs a gentle ultrasonic mist with topical oxygen to help stubborn foot wounds heal. At Annapolis Foot & Ankle Center, our board-certified podiatrists use VHT during short, in-office sessions alongside standard wound care to encourage new tissue growth and lower the risk of infection. It is one of several advanced options the practice offers for wounds that have been slow to close.
Do you have a foot wound that just will not heal? You may have started looking into newer treatment options and come across vaporous hyperoxia therapy, or VHT. This is a relatively new, noninvasive therapy designed to jump-start healing in chronic, stubborn wounds.
Below, our Annapolis podiatry team explains what VHT is, how it works, which wounds it can help, and what a typical session looks like. With this information in hand, you can have an informed conversation with your foot health team about whether it may be right for your non-healing wound.
What is Vaporous Hyperoxia Therapy (VHT)?
Vaporous hyperoxia therapy is a non-contact treatment that surrounds a wound with a low-frequency, non-thermal ultrasonic mist combined with topical oxygen - meaning oxygen applied to the surface of the skin. A small treatment chamber fits around the wound like a bubble, so nothing presses on the sore and the area is sealed. The mist and oxygen work together to create a healthier environment for healing. The therapy is FDA-cleared, painless, and can be used on several different types of skin wounds. It is one of several advanced wound healing options available for foot wounds that have not responded to basic care.
How Does VHT Help Foot Wounds Heal?
Chronic wounds often stall because the injured area does not get enough oxygen and cannot build healthy new tissue that a wound needs to close. When circulation is poor or blood sugar runs high, less oxygen reaches the skin and a wound can stay open for weeks or months. Adding oxygen at the wound site can give the healing process a boost.
VHT delivers that needed oxygen directly to the wound surface while mist creates a moist environment that stimulates new tissue growth. Extra oxygen at the wound also makes it harder for bacteria to take hold, which can lower the chance of infection. It is important to know that results vary from person to person, and VHT works best as part of a complete treatment plan tailored to your specific situation.
Vaporous hyperoxia therapy is used as a complement to, and not a substitute for, the fundamentals of wound care. Removing dead tissue, taking pressure off the wound, controlling infection, and managing underlying conditions all remain essential. Our team folds VHT into a broader strategy through our comprehensive foot wound care program so each treatment supports the others for maximum healing.
Which Foot Wounds can VHT Treat and What is a Session Like?
The good news for patients suffering from chronic wounds is that VHT can work for a range of slow-healing foot wounds. You should discuss the possibility with your podiatrist for:
- Non-healing diabetic ulcers and other wounds linked to diabetes
- Pressure sores and other long-standing chronic wounds
- Wounds caused by poor circulation, or reduced blood flow to the feet
- Surgical wounds that are slow to close
- Wounds complicated by neuropathy, or nerve damage that reduces feeling in the feet
If your foot care team decides the therapy is right for your wound, a VHT session is quick and comfortable. Each treatment usually lasts about 40 minutes and is typically scheduled two to three times per week. You simply rest while the chamber delivers the mist and oxygen around the wound, and there is no pain involved.
Many patients begin to see visible progress over the first several sessions, though the total number of treatments and the time to full healing depend on the wound and your overall foot health. You can learn more about our in-office Vaporox sessions and how they fit into a personalized plan before scheduling a consultation.
When to Discuss VHT Treatment With a Podiatrist
If a foot wound has not improved within a couple of weeks, is getting larger, or shows signs of infection, contact a podiatrist or another healthcare professional promptly. Don't ever wait out concerning symptoms such as increasing redness, warmth, swelling, drainage, an unpleasant odor, or fever. This is especially important if you have diabetes or poor circulation, because wounds can worsen quickly and quietly.
Early treatment protects the wound and can help you lower your risk of amputation. Board-certified podiatrist Dr. Eric Harmelin, who is certified in hyperbaric medicine, and the rest of our team can evaluate your wound and explain which treatments, including VHT, may help you heal.
