If the ambient pressure exceeds the pressure in the tank you will not be able to get any gas out.
In a chamber, in a building, in France. Pressure in the chamber is pumped up to simulate a dive. No one is in the ocean, no one is wet.Let me get this right - these were divers in a submersible or similar? I mean these guys weren't wearing drysuits, right? I am imagining a chamber of some sort with all the life support functions, etc lowered to those depths?
In the Trieste dive the personnel were not exposed to any pressure, the vehicle's hull kept the pressure out, in the COMEX "dives" the personnel were exposed to the pressure inside the chamber, pressure equivalent to that at of the depths indicated.L If that is the case, then what's the big deal? Did man already travel to the deepest part of the ocean in a sub in the 1970s?

Isn't that easy then? Going to 700m in a chamber just means that the human body can withstand that pressure & thats it, right?
Original post:
In 1977 - 501m in the Meditteranean Sea breathing Heliox
* In 1988 - 530m, again in the Med., breathing Hydro-Heliox ( 49/50/1 ) - 8 days to reach depth, 18 days deco.
I'm confused.
