Decompression illness is one of the most common risks to divers, often caused by a rapid ascent or when leaving a high-pressure workspace.

It is vitally important to ensure that any diver suffering from DCI is given prompt first aid treatment and that the relevant medical assistance should be sought as quickly as possible.
