Survival following accidental decompression to an altitude greater than 74,000 feet (22,555 m)
Abstract:
A man was accidentally decompressed to an altitude greater than 22,555 m (74,000 ft) in an industrial vacuum chamber. He experienced burst lung, massive decompression sickness, and sustained ebulism. He remained at altitude for a period of 3-5 min. By 5.5 h following the accident, he was still profoundly unconscious. He was subsequently treated in a hyperbaric chamber with recompression on a modified U.S. Navy Table 6A and had eventual clinical recovery. The CPK peaked at 8000 units 2 d after the accident, demonstrating substantial barotrauma to the tissues.

Variation of Atmospheric Pressure
Assuming the air temperature is constant at a given altitude and that the ideal gas law of thermodynamics describes the atmosphere to a good approximation, one can find the variation of atmospheric pressure with height.
