depressurisation
Cabin air escaping
Depressurisation is the loss or release of pressure from an enclosed space.
Aircraft cabins maintain pressure at high altitudes, so depressurisation—whether gradual or sudden—poses serious danger: Oxygen masks dropped during the rapid depressurisation.
The term applies to any pressurised system losing its seal.
Also spelled depressurization.
