Could there be that dramatic a shift in pressure if the elevator only goes 1 or 2 floors though? I can see that happening if there were more than 2 floors though. No idea what his place looked like or how many levels there were though (and I couldn't imagine living in such an opulent place like that...insanely expensive....)
I don't think it have to be a dramatic shift. bottom line, it got to do with the gravitational pull.
That's what causes the pressure change, the feeling of having "fullness in the ears", the dizziness etc.
I daresay everybody feels the shift as soon as the elevator starts and stops.
Granted, the slower the elevator, the shorter the ride - the less of the impact.
Some people are affected more, some less.
But for someone with already compromised breathing, blood pressure etc I believe it
may, not "surely does", just
may
have an negative impact.
I was just speculating about what
could have happened, not saying what surely happened, mind you
