Your HBOT session, clearly explained.

Follow an HBOT session step by step—from booking and the safety briefing to gradual pressurisation, time at 1.5 ATA and leaving the Cardiff hospital.

The equipment looks unusual. The experience follows a clear sequence: a gradual change in pressure, time to rest and an operator who remains in contact from beginning to end. The service is doctor-led through clinical governance and escalation; a doctor does not need to operate every routine session.

From booking to leaving

The session, step by step.

  1. 01

    Choose your time

    Book online. No referral needed. Every Course includes a medical consultation. For a Course, the planner proposes ten dates from the goal you select; every date remains editable before payment.

  2. 02

    Complete the declaration

    Around 24 hours before session one, we send the consent information and one course-scoped medical declaration. Reception handles the routine process and escalates anything flagged.

  3. 03

    Arrive and prepare

    The team checks the practical safety rules and what can enter the chamber. You will remove battery devices, lighters, vapes and unsuitable products before treatment.

  4. 04

    Hear the three-point briefing

    Every visit covers how to clear your ears, how to speak to the operator and how the session is stopped. You remain in control throughout.

  5. 05

    Go gradually to pressure

    The chamber inflates over roughly five to ten minutes. Your ears may feel as they do during a flight; the operator talks you through clearing them.

  6. 06

    Settle in

    At pressure, you breathe concentrated oxygen and rest. You remain able to communicate with the operator throughout.

  7. 07

    Return to normal pressure

    Decompression is gradual. Once the chamber opens, you collect your things and leave. Most people continue with the rest of their day normally.

What you may notice

Your ears are usually the main event.

The pressure change can make your ears feel full, much like take-off or landing. The team shows you simple equalisation techniques before starting, slows the change when needed and can stop the session if you ask.

What to bring

Bring yourself. We manage the equipment.

Reception confirms the clothing and personal-item rules before your appointment. Tell the team about any health change before the chamber starts so it can be handled through the approved declaration and review process.

Your first session

Trying one hour is a valid way to decide.

One session is not a substitute for a research protocol built around repeated treatment. It is useful for a different reason: you learn how your ears respond, how the chamber feels and whether returning for a course is practical.

Ready when you are

Choose one session or plan a Course.

There is no consultation gate. Choose a suitable time online; the consent and declaration follow around 24 hours before the first appointment.
