Underwater breathing apparatus
Underwater breathing apparatus is equipment which allows the user to breathe underwater. The three major categories of ambient pressure underwater breathing apparatus are:
- Open circuit scuba, where the diver carries the gas supply, and exhaled gas is exhausted to the environment
- Rebreather scuba, where the diver carried the gas supply, and exhaled gas is recycled for further use, and
- Surface supplied diving equipment, where the gas supply is provided from the surface through a diver's umbilical
Atmospheric pressure underwater breathing apparatus is also used in the form of armoured atmospheric diving suits, which maintain an internal pressure approximating surface pressure
