Okay, first thing is a cylinder of compressed air (or other gas that you're going to breathe ... could be Nitrox or another mix). Connected to the cylinder is your first stage regulator. This regulator brings the pressure of the air down from what it is in the tank (at the beginning of the dive, around 3,000 psi) down to about 150 psi. Then you have a high pressure hose (after all, 150 psi is still quite a bit of pressure). And finally at the other end of the high pressure hose is your second stage regulator, which reduces the pressure from 150 psi to "ambient" pressure ... meaning the pressure that you're at. Also, it should go without saying, you would also need WATER to breathe underwater. :-)

∙ 13y agoIn order to live underwater, we would need a supply of many things.
- Oxygen
- Food
- Water (Clean, drinkable)
- Safe environment
- Sturdy material
- A way to get help if needed
and a lot more. This is why we do not live underwater. Who knows? Maybe it is a thing of the future.
