Inside the Chamber: What to Expect During Your First HBOT Session

If you’ve never experienced hyperbaric oxygen therapy before, the idea of getting into a pressurised chamber can feel a little unfamiliar.

What will it feel like? Will your ears hurt? What do you do for the duration of the session? Can you talk to the team?

These are all perfectly reasonable questions.

At HybO2 House, we want your first experience to feel straightforward from the moment you arrive. So, here’s exactly what happens during an HBOT session.

Before you enter the chamber

Your experience starts before you even step inside.

Before your first appointment, you’ll complete a questionnaire covering your health, goals and relevant medical history. When you arrive, a member of our experienced team will sit down with you to go through this in more detail.

We’ll talk about what you’re hoping to get from HBOT, check for any contraindications, explain how the therapy works and talk you through what will happen during your session.

It’s also your opportunity to ask questions. If you’re nervous about anything, tell us. We’d much rather you feel completely comfortable before you enter the chamber.

Getting your mask fitted

Our chambers use a Built In Breathing System (BIBS) to deliver near-pure oxygen at pressure.

Before you enter, we’ll find a mask that fits you comfortably. We have multiple sizes and shapes, allowing us to find the fit that feels right for you.

We’ll check the fit and seal carefully to minimise air leaks and make sure you’re happy with it before your session begins.

Getting comfortable inside the chamber

Once you’re inside, we’ll show you everything you need to know.

Our chambers have a large, clear acrylic door, so you can see out and our team can see you throughout your session. We also have cameras positioned near the chamber so that you’re continuously monitored from reception.

You’ll be shown how to adjust the temperature within the chamber, how to speak to us from inside the chamber and where the emergency stop is.

You can bring headphones, listen to music, read a book or simply close your eyes and relax.

And if you need us at any point, you can communicate with the team through the chamber’s communication system or simply knock on the window to get our attention.

Then comes compression

Decompression: Coming back down

When your session is finished, your team member will let you know that decompression is about to begin.

The pressure inside the chamber will gradually return to normal. This generally takes around 5-10 minutes, depending on the speed that’s most comfortable for you.

Just as with compression, you may notice some popping or pressure in your ears.

And then, the chamber door opens and your session is complete!

What happens afterwards?

There’s no need to rush straight out of the clinic.

We’ll give you a glass of water with electrolytes and there’s plenty of comfortable space for you to sit, take a moment and chat with the team.

Some people describe feeling energised with HBOT, while others feel relaxed or a little sleepy. Everyone responds differently.

You may also notice that you’re hungry afterwards. Increased appetite is something we hear about regularly from our clients and it’s one reason we always encourage you to listen to your body and refuel when you need to.

Most importantly, there’s no downtime.

You can drive, work, exercise and continue with your normal day after your session.

What if I'm nervous?

Honestly, we understand.

Getting into a pressurised container for an hour to an hour and a half isn’t something most people have experienced before. It can sound much more intimidating than it actually feels.

That’s why our team is with you throughout the process.

We’ll explain what we’re doing, tell you what to expect next, help you with your ears during compression and remain in communication with you throughout the session.

If you need something changed, slowed down or explained again, just ask.

You don’t need to know how to do HBOT before you arrive. That’s our job.
