Obtaining oxygen usually okay at altitudes below 10,000ft.

Cabin pressurisation
Cabin is pressurised at altitudes above 10,000 ft to stimulate height of between 5,000-7,000ft. Takes place immediately after take-off and depressurised just prior to touch down.

Airbus and 747
Air drawn through engines, cooled, cleaned then pumped into the cabin
3 of 8
787
Takes air directly from the atmosphere through inlets on the fuselage.
4 of 8
Non-pressurisation
If cabin altitude exceeds 15,000ft they would begin to suffer hypoxia. Oxygen deploys automatically.
5 of 8
Slow decompression
Gradual loss of cabin pressure. Small cracks, The appearance of oxygen masks.
6 of 8
Rapid decompression
takes place between 1 and 10 seconds for pressure to equalise. occur at high altitudes or part of fuselage is destroyed, loud noise, mist. Airbus (chemical oxygen)
