Answer 1

Speed of change of elevation would also be a factor, but going from 500foot elevation would be less of a change than going from 6’ to the surface of the pool, 30’ of water is about 1 atmosphere of pressure and there’s no need to worry about the bends. So moving through the atmosphere would have no effect other than the lack of oxygen at altitude which is why you get the headache and flu like symptoms
