I can not see this video because I'm on Dial-Up, but I can not answer what we assume they are.
1 / Yes you are right that a gas is compressed. It must be remembered, and in the class of your PADI OW, a diver breathes from a tank filled with a reg hear gas is being taught in the same ambient pressure. What happens in the lungs, is essentially the same pressure, the outside of the lung. You can destroy the things that have the same internal and external pressure. It is a law of physics.
2 / In fact, you can use my answer to No. 1 this position is the same principle. This is the physics behind it. When the air? His lungs.
Large storage device and natural gas. You can also use it to the gas pressure in the headspace can not add yourself. They are all interconnected. Great internal road.
3 / Everybody Narco if deep enough dive. The severity depends on the person. I know what it means to be found, but usually reach only 170 metersor more. That's me. I have a friend that I did not dive 80 meters more, because I know it will be blocked. That he is. Everyone is different. So, what you ate for breakfast and can influence suseptibility
4 / O2 is that tox. O2 is toxic when metabolized in PRESSU sure it is poisonous. Exposure of normal O2 will be safe its1.44. You could blow past 1.6, but actually on the board. 1.7 is considered serious. Spit Your reg and drown, or fried, just the brain.
Contrary to popular belief, want less O2 for a deep dive, nor, for that reason. Therefore, you should learn that nitrox gas well within the parameters, but not deep gas
