Altitude.org has several fun and interactive calculators that explain the effects of ascent to high altitudes. There are online models for both the general public and for physicians.
Although there are no mountains at 9000m (29700ft) above sea level, commercial aircraft do fly this high. The pressure on the outside of the cabin of a plane at this altitude would be the same as seven and a third metres of sea water. Thankfully, the aircraft is pressurised to an altitude of around 2500m.
