How Long Can you Breathe Through Oxygen Masks?
You may have heard the safety briefing about oxygen masks many times during a flight but have you ever wondered how long you’d actually be able to breathe through one of those masks? As you know, airplane cabins are pressurized to allow passengers to breathe without any trouble.
In the case of depressurization, passengers will have to quickly put on the oxygen masks that drop from above. They last for about 10 to 15 minutes and while that may not sound like a lot of time, it’s enough for pilots to rapidly descend to an altitude where masks are no longer required.
