Question

Why does a scuba diver need a gas pressure in his/her regulator greater than 1 atmosphere

Answer 1

HEY MATE....!!

Lung tissue is delicate, and more pressure

INSIDE than out can rupture It. Conversely more

pressure outside (water depth) makes it

impossible to breathe properly, unaided. You

can't breathe through a tube held aloft if you

are more than a foot or 2 underwater. Your

diaphragm is too weak

So one other reason for having a pressurised air

tank, besides lots of storage of air, is to always

have air at the mouthpiece at about the same

pressure as the surrounding water. This

pressure increases by 1 atm for every 33 ft of

sea water.

A measure of a good regulator is to say it is

easy breathing

Hope it helps you ❤️ ✌️
