How long do divers have to decompress?

The elapsed time at surface pressure immediately after a dive is also an important part of decompression and can be thought of as the last decompression stop of a dive. It can take up to 24 hours for the body to return to its normal atmospheric levels of inert gas saturation after a dive.

What happens if you don’t decompress after diving?

If a diver surfaces without exhaling, air trapped in the lungs expands with ascent and may rupture lung tissue – called pulmonary barotrauma – which releases gas bubbles into the arterial circulation. This distributes them to body tissues in proportion to the blood flow.

What do the bends feel like?

How do I decompress after diving?

Decompression diving involves on-gassing more nitrogen, which means a diver must make a series of stops during his ascent. Each stop allows time for gas to move out of the tissues and back to the lungs. The diver then continues to move closer to the surface between each decompression stop.
