The three phases of treatment

Compression
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. 
Decompression
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. 

Possible side effects
Ear pain             Sinus pain Tooth pain Temporary worsening of short sightness	Progression of cataracts Burst lung Oxygen toxicity

Serious side effects are extremely rare.
