You breathe underwater using a a open circuit breathing apparatus which is commonly known as "S.C.U.B.A." : self contained underwater breathing apparatus.
The diver carries on his back a aluminum or steel tank, which holds compressed air.
The compressed air is reduced to a safe level to breathe using a demand regulator which is connected to the top of the tank.
This regulator is comprised of 2 stages, the 1st stage brings down the pressure from the tank which is around 2000 to 3000 psi. The pressure reduced air which is around 140 psi then travels down a hose to the 2nd stage which works on a demand system! This is the unit you see next to the divers mouth, the diver creates a seal around the mouth piece much like you would with a snorkel. A piston or a diaphragm holds back the air and only releases it when the diver breathes in. The used air that the diver breathes out is released through two exhaust ports. A Scuba diver can spend just under a hour underwater depending on how deep he dives or conditions like water temperature and comfort level.
There are several methods of working underwater where scuba is not used.
Super snorkels Float on the surface while the diver travels below, these are somewhat limited as far as depth and area travel. Hookah diving is also similar and can handle the air needs of multiple divers. Brownies third lung is one brand name. There are now several experimental methods of non scuba air supply being worked on by the U.S.Navy.
