When Hyperbaric Oxygen Therapy for Wounds Helps

A wound that remains open week after week can place a patient at risk for infection, pain, hospitalization, and loss of independence. For certain complex wounds, hyperbaric oxygen therapy for wounds can be a valuable part of a physician-directed treatment plan. It is not the right treatment for every wound, but when used for the right diagnosis and alongside skilled wound care, it may help the body do the work of healing.

At Wound Care Center of Palm Beach, the goal is always practical: identify why a wound is not progressing, address the underlying cause, and bring advanced care within reach of patients and families who need dependable support.

What Is Hyperbaric Oxygen Therapy?

Hyperbaric oxygen therapy, often called HBOT, is a medical treatment delivered inside a specialized pressurized chamber. During treatment, the patient breathes oxygen at a pressure higher than normal atmospheric pressure. This increases the amount of oxygen carried in the blood and delivered to tissues that may not be receiving enough oxygen on their own.

Oxygen is essential to wound repair. It supports the body’s ability to fight certain infections, build new blood vessels, produce collagen, and repair damaged tissue. In a chronic wound, poor circulation, diabetes, prior radiation treatment, swelling, infection, or repeated pressure can interfere with those processes. HBOT may improve oxygen availability in compromised tissue while the wound care team addresses the other barriers to healing.

This is not an at-home treatment and it does not replace wound cleaning, pressure relief, blood sugar management, circulation evaluation, or appropriate dressings. It is an advanced therapy that works best as one part of a coordinated care plan.

When Hyperbaric Oxygen Therapy for Wounds May Be Recommended

A wound does not need to be large to be serious. A small diabetic ulcer on the foot, for example, can become dangerous if blood flow is reduced, infection develops, or the person cannot feel worsening pressure because of neuropathy. A clinician may consider HBOT when a qualifying wound has not responded adequately to standard care or when the risk of tissue loss is significant.

Hyperbaric treatment is commonly considered for selected cases involving diabetic foot ulcers with deep tissue involvement, chronic bone infection that has not responded to usual treatment, compromised skin grafts or flaps, crush injuries, and tissue injury following radiation therapy. Some severe soft-tissue infections may also require urgent hyperbaric treatment as part of hospital-based care.

The diagnosis matters. Venous leg ulcers, pressure injuries, arterial ulcers, and post-surgical wounds can each require a different first-line approach. For example, compression is often central to venous ulcer care, while offloading pressure is essential for many diabetic foot ulcers and pressure injuries. If inadequate blood supply is the main concern, vascular evaluation may be necessary before advanced therapies can be effective.

That is why a recommendation for HBOT should follow a thorough wound assessment, not simply the fact that a wound has been present for a long time.

How Treatment Supports the Healing Process

During an HBOT session, the higher oxygen level in the blood can reach areas where circulation is limited and tissues are under stress. This may help reduce swelling, support white blood cell activity against infection, and encourage the formation of new small blood vessels over time. For wounds affected by radiation damage, the therapy may help improve the health of injured tissue that has struggled to heal.

The benefit is usually cumulative. Patients often receive a series of treatments rather than a single session, with the exact number based on the diagnosis, wound response, medical history, and coverage requirements. A session commonly lasts about 90 minutes to two hours, although schedules vary by facility and treatment plan.

Progress should be measured throughout care. The wound team may track wound size, depth, drainage, tissue quality, infection signs, pain, circulation, and the patient’s ability to follow the care plan. If the wound is not improving as expected, the plan should be reassessed rather than continuing any therapy without a clear clinical purpose.

What Happens Before and During HBOT

Before treatment begins, a qualified provider reviews the patient’s wound history, medications, medical conditions, prior imaging or testing, and treatment goals. The team also examines whether other correctable issues are delaying healing, such as uncontrolled diabetes, poor nutrition, smoking, infection, pressure on the wound, or inadequate circulation.

Patients are screened for safety. Untreated pneumothorax, which is a collapsed lung, is a major contraindication to hyperbaric therapy. Lung conditions, certain chemotherapy drugs, seizure disorders, ear or sinus problems, fever, and implanted devices may require additional review or a modified plan. Claustrophobia can also be a concern, but the care team can discuss what to expect and whether treatment is appropriate.

During a session, patients may feel pressure in the ears similar to an airplane descent. The team teaches ways to equalize that pressure. Some people experience temporary changes in vision after a series of treatments, and ear discomfort can occur. Serious complications are uncommon when treatment is properly screened and monitored, but HBOT is medical care, not a spa service. It should always be delivered under appropriate clinical supervision.

HBOT Works Best With Complete Wound Care

The chamber alone cannot solve the problem that caused the wound. A patient with a diabetic foot ulcer may need regular debridement to remove nonviable tissue, advanced dressings to manage drainage, infection evaluation, pressure-relieving footwear, and close blood sugar control. A patient with a sacral wound may need repositioning, support surfaces, nutrition support, and caregiver coordination.

For older adults and patients with limited mobility, consistency can be the difference between slow progress and repeated setbacks. Missed dressing changes, prolonged pressure, unnoticed drainage, or delayed reporting of redness can allow a wound to worsen quickly. Families, assisted living teams, nursing facilities, home health agencies, and referring providers all play an important role in carrying out the plan between visits.

Advanced wound care should also reduce unnecessary disruption. When clinically appropriate, mobile wound visits, coordinated transportation, and communication with caregivers can help patients receive consistent treatment without repeated emergency department trips. Hyperbaric therapy requires a specialized treatment setting, but many other parts of the wound plan can be coordinated where the patient lives.

Insurance, Eligibility, and the Value of Early Evaluation

Medicare and other insurance plans may cover hyperbaric oxygen therapy for specific approved diagnoses when medical criteria are met. Coverage is not automatic for every chronic wound, and documentation of the diagnosis, prior treatment, wound severity, and response to standard care is often necessary.

An eligibility review can clarify whether HBOT may be medically appropriate and whether other treatments should come first. Early evaluation is especially important for patients with diabetes, reduced sensation in the feet, a wound with increasing drainage or odor, black or discolored tissue, spreading redness, fever, or a wound that is becoming more painful. These changes should not wait for a routine appointment.

For referral partners, timely specialty involvement can help establish a clear treatment pathway, document wound progress, and identify when escalation is needed. For families, it can replace uncertainty with a plan that addresses both the wound and the patient’s daily realities.

A Thoughtful Next Step for a Wound That Is Not Healing

Hyperbaric oxygen therapy may offer meaningful support when a qualifying wound is threatened by poor oxygen delivery, severe infection, radiation injury, or other complex healing barriers. The best question is not simply, “Can this wound receive HBOT?” It is, “What is preventing this wound from healing, and what combination of care gives this patient the safest path forward?”

If a wound is stalled, worsening, or placing a loved one at risk, request a wound evaluation promptly. A focused assessment can determine whether hyperbaric therapy, debridement, advanced dressings, biologic treatment, offloading, circulation support, or coordinated mobile care should be part of the next step toward recovery.
