Three Phases of Treatment


Treatment chamber pressure increases and it may become slightly warm. Feelings of fullness in the ears similar to sensation during airplane take off and landing may be experienced. 

Maintenance of Pressure

Once the treatment depth is reached, activities like reading or watching a programme in the chamber entertainment system is possible, whilst breathing oxygen in a transparent hood or mask. 


Pressure is adjusted back to sea level once the treatment is complete and it will be cool. Feelings of fullness may occur again but nothing needs to be done as it is a normal sensation that will resolve naturally.

At what pressure will the treatment commence?

Treatment pressure is usually between 2 - 3 ATA, which is equivalent of 10 to 20 metres underwater. In some diving injuries, a much greater pressure may be required.
