Space has different issues but basically -1 atmosphere vs 180 atmospheres is a constant. 180 atmospheres is absolutely brutal.
Without any real justification, I invite you to imagine an elephant pirouetting on top of your skull. Hmmm, nice image, does it stack up:
180 atmos is 186 kg/cm^2 according to random online calculator. That's 2645 psi in old money, according to Google calc. An adult african elephant is about 5-6 tonnes according to several sites (max 6.8 tonnes). So 6000/186 = 32 cm^2. root 32 is about 5.7cm. I really did pluck the elephant thing out of the air and it does seem to work out (please check my 'rithmetic).
Imagine that every 5.7cm^2 of your body/vessel/submarine has an adult african elephant's weight bearing on it.
Now in space we have a bit of a problem with keeping everything in, instead of out but we can lower the internal atmospheric pressure and up the oxygen content (fire risk - procedures!) and other tricks and we have to scrub the CO2 (and so below surface). We also have to worry about very, very fast moving anything, radiation and other issues.
But in space you do not have an elephant's weight crushing each 2.5" square of your body, all the time! That's why deep sea is far more dangerous than space (which is also very dangerous).
With current technology the most dangerous part about space isn't being in space, it's getting there (and back). So far, nobody has ever died just sitting in orbit. (Closest was the Soyuz 11[1] and even that was a result of an incident during the re-entry process.)
