Like nitrogen, the body absorbs extra oxygen under increased underwater pressure as well. For most divers this is not a problem, but at extreme depths so much extra oxygen is absorbed that this life- giving gas becomes toxic . The effects include tunnel vision, nausea, twitching, loss of consciousness and seizures.
What are the dangers of scuba diving?

Is scuba diving hard on your body?
Scuba diving exposes you to many effects, including immersion, cold, hyperbaric gases, elevated breathing pressure, exercise and stress, as well as a postdive risk of gas bubbles circulating in your blood.

At what depth will water crush you?
Human beings can withstand 3 to 4 atmospheres of pressure, or 43.5 to 58 psi. Water weighs 64 pounds per cubic foot, or one atmosphere per 33 feet of depth, and presses in from all sides. The ocean’s pressure can indeed crush you.
