Oxygen Masks On Planes.?

So i watched fight club along, long time ago but i was reading a question just and it just brought the throught to mind.





Is the purpose of oxygen masks on a plane to get passengers 'high' so that they are not running around panicing when your spiraling down?





If its for low oxygen levels, then why dont you have them out all the time?Oxygen Masks On Planes.?
no, the cabin is pressurized and rapid decent causes a flux in gas levels... here Most commercial aircraft are fitted with oxygen masks for use when cabin pressurization fails.[4][5] In general, commercial aircraft are pressurized so that the cabin air is at a pressure equivalent to no more than 8,000 feet altitude (usually somewhat lower altitude), where one can breathe normally without an oxygen mask. If the oxygen pressure in the cabin drops below a safe level, risking hypoxia, compartments containing the oxygen masks will open automatically, either above or in front of the passenger and crew seats, and in the lavatories.Oxygen Masks On Planes.?
The purpose of oxygen masks is to provide supplemental oxygen in the event of depressurization at high altitude.





Normally, airliner cabins are pressurized to a pressure that is similar to that of the air at sea level or on a small mountain (e.g., the altitude of Denver). With this pressurization, you can get all the oxygen you need by breathing normally, so no masks are needed.





If the cabin loses pressure while cruising at high altitude, however, the air gets too thin to provide the oxygen you need just with normal breathing. For this reason, oxygen masks drop down for you to use until the airplane descends to an altitude where extra oxygen is not needed (which takes only a few minutes at most).





You don't get high on oxygen, although breathing pure oxygen at high pressure for an extended period can have toxic effects.
Naw, its not to get ';high'; from.





Airplanes are pressurized. It's not quite as complex as the space shuttle's life support, but an airliner's cruising altitude is in a hostile environment... the cabin of an aircraft is sort of like a giant oxygen tank with breathable air in it (it's a little more complex than that... but for simplicity), and outside the airplane the air is too thin to extract enough oxygen from for people to survive. Now... if there's a pressurization problem (like a big hole, for example) then there's not enough oxygen for the passengers to live.





';Pull the mask towards you'; as you have heard from the safety videos on airplanes. That pull will activate a chemical reaction in the oxygen canisters, which produces oxygen. This oxygen supply from the oxygen mask will only last 5 minutes on most airplanes! That's just long enough for the pilots to make an emergency descent to an altitude that people can breathe easy at.
O2 masks are only needed during rare cases of cabin depressurizations (or if you're flying an unpressurized plane at higher altitudes). In that case, they are used to counteract the effects of hypoxia and keep people from passing out.





Breathing 100% O2 will not get you 'high'. It can work wonders for a hangover, but that's for a different question.
No.





Oxygen won't get anyone high.





Panicking passengers don't run around.





There is plenty of oxygen in the cabin of an airliner.





Those who want it all the time bring their own.
