During a rapid decompression, what can happen to the body?

During a rapid decompression, gas bubbles can form in tissues due to the sudden drop in atmospheric pressure. This phenomenon occurs because the reduced pressure can cause dissolved gases in the bloodstream, particularly nitrogen, to come out of solution and form bubbles, similar to how bubbles form when a carbonated drink is opened. This is known as decompression sickness or "the bends," which can lead to serious health issues.

The body's ability to acclimate without issues is typically associated with gradual changes in altitude, not rapid changes, which can precipitate risks. The lungs are significantly affected because they contain air at higher pressure; during a rapid drop, the air expands, potentially leading to barotrauma or rupture. Additionally, the misconception that there is no risk to pilots ignores the physiological challenges posed by rapid decompression, particularly at high altitudes where the lack of oxygen and pressure is significant.
