How long does 200 bars of oxygen last?
The Average
They use standard equipment with a 80-cubic-foot cylinder filled with 200 bar of air. Dives at these levels are not deep at around 18 meters / 60 feet. Based on my experience as an instructor these dives last between 35 and 45 minutes with 20% lasting as long as 60 minutes.

Why can’t we go to the bottom of the ocean?
“The intense pressures in the deep ocean make it an extremely difficult environment to explore.” Although you don’t notice it, the pressure of the air pushing down on your body at sea level is about 15 pounds per square inch. If you went up into space, above the Earth’s atmosphere, the pressure would decrease to zero.

You can’t breath at the bottom of the ocean. If you can’t breath, your body won’t stay alive for more than about 30 minutes. (Although you’d lose consciousness after about 5.) (3) The water pressure is very high.
