What happens when I have treatment in the hyperbaric medicine unit?

Before your treatment

Do

• Take your usual medication

• Eat before you arrive

• Avoid smoking immediately before and after hyperbaric treatment

• Go to the toilet before (although there is a private area in the chamber should it be required)

Do Not drink alcohol before you arrive for your treatment

The Chamber
In order to be able to deliver a high dose of oxygen the environment must first be pressurised. It is the breathing of oxygen whilst within the recompression chamber that enables the delivery of the high dose of oxygen. The chamber is a large metal cylinder with a door. There is seating for up to five clients and two attendants. You will never be in the chamber without at least one qualified chamber attendant.

Prohibited items
To ensure your safety there are some items which are not permitted in the chamber. Click here for more information

Hoods and Collars
In order to deliver oxygen safely in the chamber you will be fitted with a plastic collar that is snug, but not tight, around your neck. A plastic see-through hood is then placed on the collar and a constantly refreshed supply of 100% oxygen is delivered into the hood.

In the Chamber
As the chamber is being pressurised it can be noisy and ear protection is provided should you require it. It will also begin to feel warm and humid. The chamber is fitted with a blower that cools the air within the recompression chamber, and every effort is made to keep everyone comfortable. At the end of the treatment, as the pressure inside the chamber is released, the air will cool and blankets are available for use during this time.

Ears
At the start of each treatment while the chamber is being pressurised you will need to "clear your ears". This is because the pressure inside the ear is dependent on the pressure in the environment and is sensitive to changes. Several techniques can be used, one involves holding your nose, closing your mouth and swallowing – water will be provided to aid this; this allows your ears to clear, which relieves the sensation of pressure.

Another technique is to hold your nose, and blow into your nose with your mouth closed, or by simple movement of the lower jaw. The best technique for you to "clear your ears" may take a while to learn. The attendant in the chamber will be able to advise you should you require help.
