What you're thinking of is Hard Science Fiction, which Subnautica tries to be to some extent, but inevitably turns to technobauble in (quite) a few areas.

And since cybernetics were hinted in a few of the logs, we could assume that they help to cope with the pressure.

Also consider the fact that we don't really know the gravity yield of the planet.
