Although the exact cause is not known with certainty, scientists suspect that the way nitrogen is under pressure in the nerve cells of the brain, the most likely cause.
The pressure increases the water like a diver rising - 1 atm 10m for every 33 feet (). By design, a regulator - the device that allows airdrawn from the tank to breathe - and supplies gas to compensate for the ambient pressure. The air you breathe under the same pressure as the surroundings. We need to help expand the lung.
But when containing compressed air, nitrogen, and reaches the bloodstream through the lungs, strange things can happen - including some of the complaints mentioned above.
