You’re immersed in a pressurized chamber breathing 100% pure oxygen—a treatment forcing oxygen directly into your plasma at supraphysiological levels. This hyperoxia reaches ischemic tissues beneath your chronic wounds, promoting healing through enhanced angiogenesis and increased nitric oxide production. Your body builds new blood vessels and strengthens endothelial function, making HBOT particularly effective for diabetic foot ulcers and stubborn non-healing pressure sores. Discover what else this remarkable therapy’s mechanisms and clinical applications truly offer.
Key Takeaways
- HBOT involves breathing 100% pure oxygen at increased pressure (2-3 times normal) to enhance oxygen absorption into tissues and promote healing.
- HBOT is FDA-approved for treating diabetic foot ulcers and other non-healing wounds by improving circulation and stimulating new blood vessel growth.
- The therapy strengthens immune response and reduces inflammation in wounds, making it effective against chronic infections like osteomyelitis.
- Treatment sessions last 60-120 minutes in a pressurized chamber with continuous monitoring by trained technicians for safety and effectiveness.
- Common side effects include pressure-related ear discomfort, temporary vision changes, and rare oxygen toxicity, requiring careful patient selection and monitoring.
What Is Hyperbaric Oxygen Therapy?
A sealed chamber filled with pressurized oxygen represents the core of hyperbaric oxygen therapy (HBOT), a treatment designed for patients whose wounds won’t heal through conventional methods.
You’ll breathe 100% pure oxygen while the chamber maintains pressure 2 to 3 times higher than normal atmospheric conditions, considerably increasing oxygen absorption into your bloodstream. This enhanced oxygenation reaches damaged tissues and stimulates healing.
HBOT works by expanding dissolved oxygen in your plasma through Henry’s law, improving delivery to compromised areas where blood vessels are restricted. The therapy also promotes angiogenesis—the formation of new blood vessels—essential for wound repair.
Sessions typically last 30 minutes to 2 hours in monoplace or multiplace chambers. You’ll experience accelerated tissue regeneration as your body harnesses oxygen’s therapeutic potential.
Conditions HBOT Treats
While conventional wound care often proves insufficient for certain complex conditions, hyperbaric oxygen therapy offers a proven alternative for accelerating healing across multiple challenging clinical scenarios.
You’ll find HBOT particularly effective for diabetic foot ulcers, where FDA approval specifically backs its use for Wagner grade 3 or higher classifications. The therapy addresses non-healing pressure sores by enhancing tissue regeneration through improved circulation and oxygenation.
For soft tissue infections like chronic osteomyelitis and gas gangrene, hyperbaric oxygen therapy effectively strengthens your immune system’s response by optimizing oxygen delivery to infected areas.
You’ll also benefit from HBOT’s proven efficacy in treating radiation injuries, including osteoradionecrosis and post-cancer treatments like radiation-induced cystitis and proctitis, where damaged tissues require enhanced oxygen for successful wound healing and symptom relief.
Preparing for Treatment

To prepare for your hyperbaric oxygen therapy treatment, you’ll complete several steps that establish the foundation for safe and effective HBOT.
First, you’ll undergo a thorough pre-treatment assessment with your healthcare provider, who’ll carefully review your complete medical history and current medications to identify any potential contraindications.
Your healthcare provider will thoroughly review your medical history and current medications to identify any potential contraindications.
You’ll then change into a 100% cotton medical gown and remove all metal objects—including jewelry and hearing aids—to guarantee maximum safety during the oxygen therapy session.
Before leaving home, arrange reliable transportation after therapy, as you may feel lightheaded or fatigued post-treatment.
Additionally, prepare your wound properly to maintain hygiene and prevent infection.
Finally, compile an extensive list of important questions and concerns to discuss with your healthcare provider before consenting to the procedure.
During Your Treatment Session
Once you’re inside the sealed chamber, you’ll lie on a table as technicians pressurize the space to deliver oxygen therapy. You’ll wear a medical gown during your session, maintaining comfort while the pressure gradually increases to 2.5 times normal air pressure.
As oxygen levels rise, you may experience ear discomfort similar to altitude changes—yawn or swallow to equalize the pressure. Trained technicians continuously monitor your condition throughout the entire procedure, ensuring your safety and addressing any concerns promptly.
You’ll breathe normally while watching television, listening to music, or simply relaxing for 30 minutes to two hours, depending on your specific healing plan.
The chamber then slowly depressurizes, returning to normal atmospheric conditions. You might feel lightheaded temporarily, but these effects typically resolve quickly.
After Your Treatment Session

You’ll experience temporary lightheadedness or fatigue following your chamber exit as your body readjusts to normal atmospheric pressure—effects that typically subside within minutes.
Technicians will slowly depressurize the chamber, prioritizing patient safety and your comfort. You’ll maintain continuous communication with the therapist, who’ll monitor any post-treatment effects and document your response.
Most patients feel rejuvenated and can resume normal activities immediately, though some report mild fatigue that doesn’t limit daily function.
Feel rejuvenated and return to normal activities immediately after treatment—most experience only mild, non-limiting fatigue.
Your treatment session represents one step in a thorough healing plan. Ongoing monitoring remains essential for effective recovery, so you’ll receive detailed follow-up care instructions.
The number of hyperbaric oxygen therapy sessions needed depends on your wound’s extent and body response. This personalized approach guarantees best results as you progress toward healing.
Risks and Side Effects
While hyperbaric oxygen therapy proves remarkably safe for most patients, certain side effects can occur during or after your treatment sessions. You’ll encounter risks spanning multiple categories: pressure-related injuries, vision changes, oxygen toxicity effects, anxiety responses, and metabolic concerns in diabetic patients. Pressure-related injuries to your ears and sinuses represent the most common complications, ranging from mild discomfort to serious eardrum rupture requiring immediate medical intervention. Temporary nearsightedness affects 20-40% of patients receiving multiple treatment sessions. Oxygen toxicity rarely causes serious convulsions and respiratory symptoms. Claustrophobia may trigger panic attacks in the confined chamber environment. Diabetic patients require careful monitoring for dangerous low blood sugar episodes. Understanding these side effects enables you to properly serve patients through thorough informed consent.
| Side Effect | Patient Population |
|---|---|
| Pressure-related ear and sinus injuries | Most common; 2-45% incidence rate |
| Temporary nearsightedness | 20-40% of patients receiving multiple sessions |
| Oxygen toxicity seizures | Rare but serious; requires vigilance |
| Claustrophobia and anxiety | Manageable with sedation and support |
| Low blood sugar episodes | Diabetic patients; requires monitoring and prevention |
Conclusion
You’ll find that hyperbaric oxygen therapy can markedly accelerate your wound healing by delivering 100% oxygen at elevated pressure. You’re fundamentally forcing pure oxygen into your bloodstream, which stimulates new blood vessel growth, boosts collagen production, and enhances your immune system’s ability to fight infection. While you may experience minor ear discomfort, the proven benefits far outweigh the risks. You’ll discover that HBOT can effectively heal those stubborn wounds that conventional treatments simply haven’t resolved.
