Hyperbaric Oxygen Chamber in London

A hyperbaric oxygen session takes place inside a pressurised chamber, where participants breathe oxygen while seated or reclining comfortably. The chamber operates at a higher air pressure than normal atmospheric conditions, creating a controlled environment for the session. Our chamber can operate up to 2.0 ATA (twice normal atmospheric pressure). Sessions are overseen by our team to ensure the environment remains calm, consistent, and comfortable. Hyperbaric oxygen sessions at Battersea Park Clinic are offered as part of our wellbeing services and are not described or promoted as medical treatment. No claims are made about physiological effects or health outcomes.

At Battersea Park Clinic, we offer an introductory consultation where you can speak with a trained team member about what a session involves, ask practical questions, and decide whether the experience feels appropriate for you. These discussions are intended to support informed choice and are not a medical assessment. Hyperbaric oxygen sessions are offered as part of our wellbeing services and are not described or promoted as medical treatment. We encourage anyone new to hyperbaric oxygen sessions to consider speaking with a qualified healthcare professional before booking, particularly if they have existing health conditions or concerns about suitability.

Step 1: Gradual pressurisation The chamber is slowly pressurised to up to 2.0 ATA (twice normal atmospheric pressure) over approximately 30 minutes, allowing time for you to adjust comfortably. Step 2: Session time The chamber remains at the selected pressure while you relax inside and breathe oxygen through the built-in breathing system (BIBS) mask. You can sit or recline, listen to audio, or watch TV during this time. Step 3: Gradual return to normal pressure At the end of the session, the chamber is slowly returned to normal atmospheric pressure before you leave the chamber.

There are two parts to every hyperbaric oxygen session: 1. The time it takes for the chamber to gradually pressurise to up to 2.0 ATA 2. The time spent inside the chamber at the selected pressure For a 60-minute session, around 30 minutes is used for gradual pressurisation, followed by approximately 30 minutes spent inside the chamber at pressure. For a 90-minute session, the pressurisation process is the same (around 30 minutes), followed by approximately 60 minutes spent inside the chamber at pressure. The main difference between the two options is simply how long you choose to remain inside the chamber once the desired pressure has been reached.

At the start of your session, oxygen will begin to flow through the mask and the pressure in the chamber will gradually increase. You may notice a feeling of pressure in your ears, similar to what you might experience when taking off or landing on a flight. This usually lasts for around 10–15 minutes, and our team will guide you on simple techniques to help relieve any discomfort if needed. Once the selected pressure is reached, most people find the experience calm and comfortable. You can sit or recline, breathe normally, and relax during this part of the session. Towards the end of the session, the chamber is gradually returned to normal pressure over around 10 minutes. You may notice a gentle popping sensation in your ears as the pressure changes. Many people describe sessions as peaceful and relaxing.

To help keep sessions comfortable and safe, we ask everyone to follow these guidelines before entering the chamber. What to wear • Wear comfortable, loose-fitting clothing made from 100% cotton only • Please do not wear synthetic fabrics (including nylon, polyester, or sportswear) • Jewellery should be removed before your session Please avoid before your session • Makeup, perfume, aftershave, deodorant, hairspray, body spray, or essential oils • Alcohol or recreational drugs before your session • Carbonated drinks for around 4 hours beforehand • Arriving with a very full stomach or having eaten a heavy meal within 1 hour • Mobile phones or electronic devices (these cannot be taken into the chamber) • Hand warmers, battery-powered items, or anything flammable • Excessive paper (books are fine in moderation, but loose paper is not permitted) Medications If you take regular medication, we recommend checking with a healthcare professional if you have any questions about suitability before booking a session. Why these rules matter These guidelines are in place due to the high-oxygen, pressurised environment inside the chamber and help ensure a safe, calm experience for everyone.

There is no fixed number of sessions that suits everyone. How often someone chooses to book sessions, and over what period of time, is a personal decision based on individual preference. Some people choose to try a small number of sessions first, while others prefer to book a series of sessions as part of their wider wellbeing routine. Our team are happy to explain what sessions involve and help you understand the different booking options available, so you can decide what feels right for you. Hyperbaric oxygen sessions are offered as part of our wellbeing services and are not described or promoted as medical treatment.

If you would like to book a hyperbaric oxygen session, we ask all new clients to complete a short health questionnaire before their first visit. This helps us identify any practical or safety considerations and ensure that sessions are managed appropriately. Battersea Park Clinic also offers an introductory consultation for new clients. This provides an opportunity to: • Discuss what a session involves • Ask practical questions • Review any relevant information from your questionnaire • Decide whether the experience feels appropriate for you These conversations are intended to support informed choice and safe participation. They are not a medical assessment, diagnosis, or prescription. Completion of the questionnaire and introductory consultation is required before your first session, as part of our standard safety process.

We use a hard-shell Monoplace Hyperbaric Oxygen Chamber, designed for single-person use. The chamber is pressurised for each session, and oxygen is delivered through a built-in breathing mask. The chamber features a large clear viewing window, allowing you to see outside during your session. Our team remain nearby and available throughout, and there is a two-way intercom system so you can communicate with us at any time.

Sessions take place in a controlled environment and are overseen by trained staff to ensure procedures are followed consistently and calmly throughout. Hyperbaric oxygen sessions are offered as a wellbeing experience and are generally well tolerated. However, as with any pressurised environment, some people may experience temporary sensations or discomfort. Possible experiences can include: • A feeling of pressure in the ears (similar to flying) • Sinus pressure or congestion • Temporary changes in vision • Feelings of claustrophobia in enclosed spaces • General discomfort related to pressure changes These experiences are usually mild and temporary. Our team will explain what to expect before your first session and are available to provide guidance during your time in the chamber. You will be asked to review and acknowledge information about the session process before your first booking. If you have any medical conditions or concerns about suitability, we strongly encourage you to speak with a qualified healthcare professional before booking.
