Beginner's Guide to Hyperbaric Oxygen Therapy
A first visit guide to hyperbaric oxygen therapy in Perth, explaining chamber types, pressure, oxygen delivery, screening and what happens during a session.
Written and reviewed by Perth Recovery Guide · Last reviewed 5 September 2026
In brief
HBOT involves breathing oxygen in a pressurised environment. Perth providers use different hard shell and soft shell chambers, pressures and oxygen systems, so confirm exactly what is offered before comparing prices.
This guide is for: People considering a first Perth hyperbaric session who need to compare chamber type, pressure, oxygen delivery, screening and supervision before booking.
Why people consider hyperbaric oxygen
In a pressurised chamber, higher pressure allows more oxygen to dissolve in blood plasma. Medical HBOT uses this effect for defined conditions under clinical protocols. Wellness clients may seek it for recovery or energy, but a commercial session is not automatically equivalent to hospital treatment.
- The chamber type, pressure and method of oxygen delivery determine what treatment is actually being provided
- Established medical benefits should be separated from broader performance and longevity claims
- Screening and trained supervision are central to a worthwhile first session
How a hyperbaric session works
Increasing pressure allows more oxygen to be carried in the blood plasma when high concentration oxygen is breathed. In medical settings, the pressure and oxygen protocol are selected for a recognised indication. Commercial wellness facilities may operate at lower pressures or use different oxygen delivery arrangements.
Hard shell and soft shell chambers
Hard chambers are rigid and may operate across a wider pressure range. Soft chambers use a flexible structure and commonly operate at lower pressure. The terms HBOT, mild hyperbaric therapy and oxygen therapy are not always used consistently in advertising, so ask for the chamber pressure in ATA and how oxygen is delivered.
- Confirm whether the chamber is pressurised with air or oxygen
- Ask whether oxygen is supplied through a mask or another system
- Check the usual pressure and session duration
- Ask who supervises the chamber and how you communicate during treatment
What to expect at your first booking
You should complete health screening and receive safety instructions before entering. During pressurisation, your ears may feel similar to takeoff or diving. Staff should explain pressure equalisation, items that cannot enter the chamber and how to stop the session if you feel unwell.
Planning a Perth session
Before choosing a facility, connect the service to what you actually want from the visit. These practical checks make it easier to compare venues and arrive prepared.
- Ask whether the chamber is hard shell or soft shell and what pressure is used
- Confirm whether you breathe oxygen directly or breathe the chamber air
- Complete the provider screening honestly and ask what staff supervision is present throughout the session
- Follow restrictions on clothing, electronics, cosmetics and other items because oxygen enriched environments require strict fire safety
Prices, session formats and opening arrangements can change. Use the directory to compare options, then confirm the current details through the linked official business website.
What the evidence can tell us
Medical HBOT has recognised clinical uses, but Perth wellness providers use different chambers, pressures and oxygen delivery systems. A low pressure wellness session should not be assumed to be equivalent to hospital hyperbaric treatment.
Common questions
What does ATA mean?
ATA describes atmospheric pressure. One ATA is approximately normal sea level pressure, while a chamber operating at 1.5 ATA is pressurised above that level.
Practical next step: Before paying, ask about chamber pressure, oxygen delivery, operator training, screening, supervision and the evidence for your specific reason for attending.
Will my ears feel pressure?
They may. Ask staff to explain gentle equalisation and tell them immediately if you cannot clear discomfort.

Can I take my phone inside?
Often no. Fire and equipment safety rules are strict in hyperbaric environments. Follow the individual facility instructions.
