Do airplanes carry emergency oxygen?

In general, airlines do not provide medical oxygen, but allow passengers to bring a battery-powered portable oxygen concentrator (POC) for use in flight. POCs that are approved by the Federal Aviation Association (FAA) can be purchased or rented through an oxygen supplier.

If oxygen deficiency continues over a long enough period of time, it can cause unconsciousness, permanent brain damage or even death. So, in order to keep everyone maintained with enough oxygen, the masks fall down and provide a personal flow.

If anything happens to the pressurization system, or the plane experiences any difficulties while in flight, oxygen masks will deploy. Oxygen masks supply roughly 10-14 minutes of oxygen, which is more than enough time for a pilot to descend below 10,000 feet, where the atmosphere has enough oxygen.

Sure, everyone knows that you have to use supplemental oxygen if you fly more than 30 minutes at cabin pressure altitudes of 12,500 feet or higher. And that at cabin altitudes above 14,000 feet pilots must use oxygen at all times.

According to Airbus, if a plane loses pressure at 40,000 feet, those on board have as little as 18 seconds of “useful consciousness” without supplemental oxygen. Once the euphoria is over, hypoxia renders one unconscious and can cause brain damage or death. So wear the mask.

A simple pulse oximeter reading while you are at high altitude, at rest and during activity, can determine if oxygen is needed at altitude. Alternatively, some pulmonary function labs can perform an altitude simulation test to determine your oxygen saturation at altitude.

When you fly on an airplane, the flight attendant instructs you to “put your oxygen mask on first,” before helping others. Why is this an important rule for ensuring survival? Because if you run out of oxygen yourself, you can't help anyone else with their oxygen mask.

Airlines “pressurize” the air in the cabin, but not to sea-level pressures, so there's still less oxygen getting to your body when you fly, which can make you feel drained or even short of breath. The potential dehydration factor and sitting for long periods of time doesn't help.
