More oxygen. Delivered differently.
Your red blood cells can only carry so much oxygen. Under hyperbaric pressure, oxygen also dissolves directly into your plasma, increasing the amount available to tissues throughout the body.
That is the science behind HBOT.
Why people use it varies. Recovery. Mental clarity. Energy. Performance. The strength of the evidence varies too, and we will always tell you where it stands.
How it works, in full
Whatever you’re dealing with, see what it could change.
The most common reasons are below. Each one comes with what the research actually shows—including where it runs thin, and who should not go in.
Every Course includes a 20-minute doctor consultation to discuss your history, the underlying reason you are considering HBOT and whether the evidence fits it.
There are more than six. We publish what the research shows for every reason people come here—including the ones where it shows very little.

A named doctor leads it
Dr Rukhsana Jabar (GMC 7265326), with a background in acute medicine and A&E, is the medical lead for the service. She holds overall clinical supervision—the screening standards, the governance and the escalation route all sit under her. A medical consultation is included with The Course.
Inside a registered hospital
Treatment takes place inside RosMedics (Pontcanna Hospital), an HIW-registered independent hospital—with the privacy and personal attention of a small specialist service.

Your ears may feel as they do on a flight. The operator talks you through it, and you can stop at any point.

Decompression is gradual. The chamber opens, you collect your things and go. Most people carry on with their day as normal.

Hyperbaric oxygen therapy in Cardiff: your questions answered.
Direct answers about HBOT, the chamber, prices, medical screening and booking.
What is hyperbaric oxygen therapy (HBOT)?
Hyperbaric oxygen therapy, usually shortened to HBOT, means breathing concentrated oxygen inside a chamber where the air pressure is higher than normal. At HBOT Medics, one person uses the chamber at a time for a 60-minute session at 1.5 ATA.
Understand how HBOT works →Where can I book hyperbaric oxygen therapy in Cardiff?
HBOT Medics provides hyperbaric oxygen therapy at The Mews, 38 Cathedral Road, Cardiff CF11 9LL, with the entrance via Sophia Walk. Treatment takes place inside an HIW-registered independent hospital in Pontcanna.
See the Cardiff clinic →How much does HBOT cost in Cardiff?
One 60-minute HBOT session costs £95. A ten-session Course costs £750.
Compare HBOT prices →Do I need a GP referral to book HBOT?
No GP referral is needed. Medical consultation is included with the Course, and every patient must complete a health declaration before entering the chamber so any clinical flags can be reviewed.
What conditions is hyperbaric oxygen therapy used for?
HBOT is established for a limited number of medical indications. It is also studied for problems including persistent symptoms after head injury, radiation injury and wound healing, but the evidence is not equally strong for every condition. Our condition guides publish the positive, mixed and negative findings separately.
Find the evidence for your condition →Does hyperbaric oxygen therapy hurt?
HBOT should not be painful. The pressure change can make your ears feel full, similar to take-off or landing in a plane. The chamber pressurises gradually, the operator helps you clear your ears, and you can ask to slow or stop the session at any time.
Is HBOT safe, and what are the side effects?
HBOT is generally low risk when people are screened and the session is properly supervised. The most common difficulty is pressure in the ears or sinuses. Your medical declaration checks for conditions, medicines and current treatments that may require review before you enter the chamber.
Read the HBOT safety guide →Who should not use a hyperbaric chamber?
Someone with an untreated pneumothorax, or collapsed lung, must not have HBOT. Lung or chest problems, a cold or blocked sinuses, difficulty clearing the ears, pregnancy, some medicines and active medical treatments may also need individual review. A flagged answer does not always mean you cannot have treatment.
Check who should not use the chamber →What if I feel claustrophobic inside the HBOT chamber?
The chamber is transparent, but it is still an enclosed space. You remain in contact with the operator throughout and can stop at any point. Trying one session before committing to a Course is a sensible way to learn how the chamber feels.
How long can concussion symptoms last—and is it too late if mine never went away?
Persistent post-concussion symptoms can continue for months or years. A 2025 trial of HBOT treatment included people whose symptoms had lasted from six months to ten years, but that study cannot predict an individual result. Our head-injury evidence guide explains the protocol, findings and limits.
Read the concussion evidence →My wound is not healing. Is hyperbaric oxygen therapy an option?
A wound that is not healing needs assessment and proper wound care; a private hyperbaric chamber is not a replacement for that. HBOT is established for selected problem wounds in specialist settings, while guidance and evidence vary by wound type. We will tell you when your existing clinical route should come first.
Read the non-healing wound guide →Could HBOT fit into my hair transplant recovery and aftercare?
Hair transplant swelling and concern about grafts are common reasons people investigate recovery options. Keep following your surgeon's hair transplant aftercare instructions. The published HBOT research used different chamber pressures from ours, so we explain that limitation rather than promising faster recovery or graft survival.
Read the hair transplant recovery evidence →Can I try one HBOT session before buying a course?
Yes. Try One is a single 60-minute session for £95, so you can experience the chamber before deciding whether to book a course.
Start in the way that suits you.Try One session for £95, or choose the £750 Course. You’ll review every appointment before you pay.
