Normally, if you follow safe diving limits by using dive tables and / or computers, you are at very very low risk
of decompression sickness.
The problem with an uncontrolled ascent (regardless of it happening due to expanding air or water pushing up) is an increased risk
of Decompression sickness, lung over expansion injury or a gas embolism.
Flying after diving increases the risk
of decompression sickness: because of the high concentration of nitrogen in your blood, gas bubbles can form within your body and generate health issues.

of the bloodstream, but also reduced the amount

decompression sickness, how your gear works, and lots
of other information on diving safety.
It is this higher percentage
of oxygen, and the proportionately lower percentage

decompression limits, shorten surface intervals and get an added safety buffer for
decompression sickness in certain diving circumstances.
