eli5 how do saturation divers actually stay under pressure when they’re brought up to the surface while not diving?

Perhaps I have no idea how pressure works but when sat divers are under water they have additional pressure added due to the water essentially compressing their bodies right? So how exactly can you mimic that when they’re brought up from the depth in between dives?

Basically how does pressure work?

They are in a chamber with pressurized air at the same pressure as the water where they work. You transport the diver in a pressurized chamber from where they work to where they live, so they are under constant pressure.

Air is compressible so you just need to force enough air it to get to the pressure you like. Tires you pump up with air are chambers with higher pressure inside then on the outside
