More dissolved oxygen
Inside the chamber, increased pressure allows plasma to carry substantially more dissolved oxygen.
When recovery still feels incomplete
Could better oxygen delivery support your next stage?
Hyperbaric oxygen therapy changes the physical environment around living tissue. Explore what that may mean, where human evidence exists, and whether an assessment makes sense for you.
Clear explanations · medical screening · no promises of a cure
The idea in three steps
HBOT does not perform the repair.
It may improve the conditions around it.
Pressure allows more oxygen to dissolve directly into blood plasma. That can create a stronger oxygen gradient into nearby viable tissue and may support selected repair processes.
Delivery to viable tissue
A stronger gradient may help oxygen move further from functioning capillaries into living, stressed tissue.
Better repair conditions
Available oxygen may support cellular energy, collagen, immune activity and microvascular repair.
The honest boundary: HBOT cannot revive dead tissue, reopen a blocked artery or replace surgery, antibiotics or appropriate specialist care.
Start with your situation
What are you trying to understand?
Potential benefit depends on the diagnosis, timing, tissue viability and treatment protocol. Choose a topic to see the human evidence and its limitations.

Clinical judgement before treatment
A useful assessment answers three questions.
Could oxygen delivery matter?
We consider diagnosis, timing, viable tissue, circulation and care already under way.
What does the evidence support?
We separate recognised indications and human evidence from mechanisms or unproven claims.
Can it be delivered safely?
We screen ear, lung, medication and other factors, and arrange medical review when needed.
Measured at our Wellington clinic
Real observations.
Not promises.
These de-identified before-and-after cases show what changed for individuals who completed a course and repeated the same cognitive assessment. They cannot prove that HBOT alone caused the result.

Questions people ask us.
Open any question for a direct answer.
Ask your own question →My doctor does not know much about HBOT. What should I do?+
HBOT is a specialist field. With your permission, we can share the proposed indication, protocol, evidence and safety considerations with your doctor. Treatment should complement appropriate medical care, not bypass it.
What can go wrong?+
Ear or sinus pressure injury is the most common problem. Temporary short-sightedness can occur during a longer course. Less common risks include oxygen-related seizure, lung pressure injury, low blood sugar in susceptible people and confinement anxiety. Strict screening, chamber rules and monitoring reduce risk; an untreated pneumothorax is an absolute contraindication.
What is a session like?+
After a safety check, pressure rises gradually and your ears may feel like they do on an aircraft descent. At treatment pressure you breathe high-concentration oxygen through your own mask while sitting comfortably. A standard treatment session is approximately 90 minutes, including controlled compression and decompression.
How many sessions will I need?+
It depends on the condition, timing, protocol and response. Some acute indications use only a few treatments. Many wound, radiation-injury and longer-standing rehabilitation protocols use around 20–40 sessions; some studied protocols use 60. We review rather than assume.
How soon might I notice improvement?+
There is no reliable number for everyone. Some people report change within 10–20 sessions, others later, and some do not improve. We establish a baseline and reassess relevant symptoms or function instead of relying on one good or bad day.
What is the most effective way to get benefit?+
Use the right protocol for the right problem, attend consistently and continue the medical or rehabilitation care HBOT is intended to support. Sleep, nutrition, hydration, smoking avoidance and management of conditions such as diabetes also matter. More pressure is not automatically better.
Is it guaranteed to work for me?+
No. Evidence is strong for some recognised conditions, promising but incomplete for others, and weak for some claims. We can explain the evidence and agree on a realistic objective, but we cannot guarantee an outcome.
Will I be in a chamber with other people?+
You may share a multiplace hard-shell chamber with other screened patients. Each person uses an individual oxygen mask and is monitored. Tell us if sharing concerns you so we can explain the planned arrangement.
I cannot get to Wellington. Are there other options?+
Hyperbaric providers also operate in Palmerston North, Timaru, Auckland and Cambridge. Chamber type, pressure, clinical oversight and accepted indications differ, so confirm current arrangements directly before travelling.
What if ACC is unfamiliar with HBOT?+
ACC has a formal non-acute HBOT service schedule, although case-manager familiarity varies. Funding is limited to eligible covered injuries and specified circumstances, and prior approval may be required. ACC makes the funding decision; we can help provide clinical information.
Can I see a doctor—and can I self-refer?+
Yes to both. You can contact us directly, and a medical review can be arranged when appropriate or requested. Self-referral is not automatic treatment: screening may show that records, tests or input from your doctor are needed first.
