The Role of Oxygen Therapy in Healing Wounds

Wounds that won’t heal. Days turn into weeks. Frustration builds.

You’re doing everything right—but that ulcer, that surgical cut, that chronic sore just lingers.

Why does this happen? Why won’t your skin repair like it used to?

Often, it comes down to oxygen—or the lack of it. Your body needs oxygen to heal. Period. But poor circulation, diabetes, or damaged tissue can block oxygen from getting where it’s needed most.

Enter: oxygen therapy.

This isn’t some spa trend. It’s science-backed medicine, used in hospitals, wound care clinics, and rehabilitation centers around the world. Cleveland Clinic notes its powerful benefits in regenerating tissue. Even the NIH supports oxygen’s role in chronic wound care.

Whether through a pressurized chamber or a topical delivery system, oxygen therapy gives your cells what they crave: pure, concentrated oxygen. It stimulates blood vessels. It calms inflammation. It speeds tissue growth. It helps your body win the healing battle.

Let’s break down how it works—and when it’s the right choice.

 

Oxygen Therapy for Wounds: What Makes It So Effective?

Oxygen therapy for wounds is not a blanket solution—it’s a targeted tool that supercharges the body’s natural healing process. Here’s how it works in real-world care:

Oxygen Fuels the Body’s Healing Engine

Every wound requires energy to heal. Oxygen is that fuel. Without it, critical processes like angiogenesis (new blood vessel growth), collagen synthesis, and immune response stall.

At OWC Center, we often see patients whose wounds haven’t responded to weeks of standard care. Once oxygen therapy is added, the body finally gets what it’s been missing.

Common Conditions That Benefit from Oxygen Therapy

• Diabetic foot ulcers
• Pressure sores (bedsores)
• Non-healing surgical wounds
• Radiation injuries
• Vascular ulcers or ischemic wounds

In these cases, standard dressings and antibiotics may not be enough. But by integrating oxygen directly into the healing zone, we ignite cell function and restore progress.

Real Stories, Real Recovery

We treated a patient with a deep diabetic foot ulcer who had nearly lost hope. After three weeks of hyperbaric oxygen therapy (HBOT), his wound size decreased by 50%. Why? His body finally got the oxygen it was missing for months.

Oxygen therapy for wounds works best when paired with proper wound care protocols—debridement, infection control, and offloading strategies. It’s never just one thing; it’s a system. And oxygen? It’s often the keystone.

Advanced Wound Care: Hyperbaric vs. Topical Oxygen Therapy

Understanding the differences between types of oxygen therapy is crucial when developing a personalized wound care plan.

Hyperbaric Oxygen Therapy (HBOT)

This is the most recognized form of oxygen therapy. During HBOT, the patient lies inside a pressurized chamber and breathes 100% oxygen. This process super-saturates the blood with oxygen and delivers it deep into tissues.

Key Benefits of HBOT:

• Delivers oxygen 15x higher than normal tissue saturation
• Reduces inflammation and edema
• Stimulates the formation of new blood vessels (angiogenesis)
• Boosts the effectiveness of antibiotics

 

Topical Oxygen Therapy

This method involves delivering oxygen directly to the wound site through specialized dressings or localized oxygen delivery devices. It’s especially helpful for:

• Patients who can’t tolerate HBOT
• Smaller, surface-level wounds
• Home-based or outpatient care

Which Option Is Right for You?

Your wound care specialist at OWC Center will assess factors such as:

• Wound depth and severity
• Circulatory status
• Comorbidities (e.g., diabetes, vascular issues)

This collaborative process ensures that every patient gets the right oxygen therapy at the right time. This research summary dives deeper into efficacy comparisons.

 

Wound Healing Treatments: How Long Does It Take to See Results?

Let’s be honest—everyone wants fast results. But with wounds, speed comes from precision, not shortcuts.

Typical Timelines for Oxygen Therapy

• HBOT: 90-minute sessions, 5 days a week, over 4–6 weeks
• Topical Oxygen: Daily application with dressing changes or device sessions

What Results Can You Expect?

Here’s what many OWC Center patients report:

• Noticeable reduction in wound size within 2–3 weeks
• Decreased pain and inflammation
• Enhanced tissue regrowth and color
• Lower risk of infection recurrence

Factors That Influence Healing

• Nutrition: Protein-rich diets and vitamins A, C, and zinc
• Blood sugar control (especially in diabetic patients)
• Offloading techniques to remove pressure from the wound
• Smoking cessation (smoking blocks oxygen absorption!)

Our care team tracks progress at every visit and adjusts treatment as needed. Your story matters. Your healing journey is ours, too.

 

Risks, Side Effects, and Monitoring in Oxygen Therapy

Oxygen therapy is safe—but it’s not risk-free. Let’s break it down clearly.

Common Side Effects of HBOT

• Mild sinus or ear pressure
• Temporary vision changes
• Lightheadedness or fatigue post-treatment

Rare Risks

• Claustrophobia during chamber sessions
• Lung issues (only in patients with specific underlying conditions)
• Oxygen toxicity (rare and usually only in extreme long-term exposures)

How OWC Center Protects You

• All patients are screened for risk factors prior to treatment
• Sessions are supervised by trained hyperbaric technicians
• We use protocols approved by the Undersea & Hyperbaric Medical Society

5 Safety Tips for Patients Receiving Oxygen Therapy:

1. Always disclose your full medical history
2. Avoid alcohol or carbonated drinks before sessions
3. Never bring flammable materials into the chamber
4. Wear cotton clothing (no synthetics)
5. Tell your care team immediately if you feel discomfort

For patients struggling with slow-healing or chronic wounds, oxygen therapy can make all the difference. Whether it’s through hyperbaric oxygen in a pressurized chamber or targeted topical applications at the wound site, this treatment provides the essential fuel the body needs to regenerate tissue, reduce inflammation, and fight off infection. It’s not a one-size-fits-all approach—but when applied correctly, oxygen therapy can jumpstart the healing process, even in wounds that haven’t responded to weeks of standard care.

From diabetic foot ulcers and surgical complications to pressure sores and radiation injuries, oxygen therapy has proven effective across a range of complex conditions. The treatment timeline varies—HBOT may require several weeks of daily sessions, while topical methods can be administered at home. Patients often report decreased pain, visible tissue regrowth, and a marked improvement in wound size within the first few weeks.

What sets oxygen therapy apart is how it integrates with a full wound care protocol. It’s not a magic bullet—but when combined with debridement, nutritional support, blood sugar management, and offloading strategies, it becomes a vital part of a larger healing system. And with careful patient screening and monitoring, the risks remain low and the benefits high. In the end, the goal is simple: restore healing, reduce suffering, and help every patient get their life back.

Oxygen therapy isn’t for every wound—it’s most often used for wounds that are stubborn, slow to heal, or affected by chronic conditions like diabetes, vascular disease, or radiation damage.

Common signs that oxygen therapy may be needed include:

• Wounds not healing after 30 days of treatment
• Chronic ulcers (especially diabetic foot ulcers)
• Surgical wounds with complications
• Pressure injuries or bedsores
• Radiation-injured tissue

At OWC Center’s wound healing programs, oxygen therapy is typically introduced after a full wound assessment, including tests to measure blood oxygen levels and tissue viability.

This therapy often runs alongside treatments like debridement, proper dressings, and infection control to ensure comprehensive care.

 

3. What are the different types of oxygen therapy used in wound healing?

There are two main types of oxygen therapy used for treating wounds:

1. Hyperbaric Oxygen Therapy (HBOT)

• Patients breathe 100% oxygen in a pressurized chamber.
• Increases oxygen concentration in the blood and delivers it deep into tissue.
• Often used for severe wounds, including those from diabetes or radiation.

2. Topical Oxygen Therapy

• Oxygen is delivered directly to the wound site via a specialized dressing or device.
• Non-invasive and ideal for patients who may not tolerate HBOT.

At OWC Center’s hyperbaric care facilities, the right type of therapy is selected based on your wound’s size, location, and underlying causes. It’s a collaborative decision between your wound care specialist, primary doctor, and sometimes your vascular team.

 

4. Are there any risks or side effects of oxygen therapy?

While oxygen therapy is generally safe, especially when administered under medical supervision, there are some potential risks and side effects to consider—especially with HBOT.

Possible side effects of HBOT may include:
