What is a normal oxygen saturation level on a plane?

The mean [range] (SD) SpO(2) for all flights at ground level was 97% [93-100] (1.33) and at cruising altitude 93% [85-98] (2.33). Fifty-four per cent of passengers had SpO(2) values of 94% or less at cruising altitude. This is a value which may prompt physicians to administer supplemental oxygen in hospital patients.

While the results tend to over-estimate the number of patients requiring in-flight oxygen, they are considered a safe “estimate” as to who can safely fly. Here is how the algorithm works: If the patient has resting saturations of less than 92% they require supplemental oxygen in-flight.

The only oxygen equipment allowed on an airplane is the portable oxygen concentrator (POC). If you need oxygen in flight, you must take a portable oxygen concentrator with you, and , you must let your airline know ahead of time. They may require a doctor's letter to verify the need for the POC on the plane.

The hypoxic challenge test, also known as a fit to fly test, recreates the oxygen levels on an aeroplane and measures how your body responds. The test involves breathing in air containing less oxygen than normal and seeing how it affects you in a controlled environment.

Choose a seat in the middle of the plane. As the air circulates across the rows and not up and down the plane, some experts believe the worst air is in the front or the back of the plane. Stay well hydrated by drinking lots of fluids (water or fruit juice) and avoiding caffeine and alcohol, which will dehydrate you.

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.

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.

Masks will automatically drop ' And they will. Any cabin depressurization above a certain altitude (usually around 14,000 feet) will cause the panels of the chambers containing the masks to automatically open, and the masks to drop down. This can, of course, be done manually by the cockpit crew as well.

Treatment of Hypoxia If hypoxia is suspected in yourself or others on board an aircraft, follow these simple steps: Administer supplemental oxygen (don your oxygen mask) Check your equipment for proper operation. Ensure the regulator is turned on.

For best protection, you are encouraged to use supplemental oxygen above 10,000 feet MSL. At night, because vision is particularly sensitive to diminished oxygen, a prudent rule is to use supplemental oxygen when flying above 6,000 feet MSL. So, when you fly at high altitudes, supplemental oxygen is the only solution.

If your blood pressure is higher than 120 over 80, seek medical advice before you travel.

Just like a bag of peanuts mid-flight, air pressure changes will cause you to inflate. A build-up of gas can lead to bloating, constipation and stomach pains. Lack of movement leads to fluid build-up around the body, increasing the risk of deep vein thrombosis (DVT).

Answer: No. The cabin is pressurized between 6,000 and 8,000 feet on long flights. Adding supplemental oxygen is not necessary, because the percentage of oxygen is the same as being on the ground at those altitudes.

Airlines are not required to provide oxygen service and many do not. Passengers may carry portable oxygen concentrators (POCs).
