What is the highest altitude you can fly without oxygen?

When the altitude of an airplane is less than 12,500 feet, there is no supplemental oxygen required for anyone in a private plane. From 12,500 feet to 14,000 feet, supplemental oxygen must be used by the required flight crew for any portion of the flight that is more than 30 minutes.

Is there an oxygen level chart for altitude?

Below is an altitude oxygen chart that extrapolates oxygen percentages to real altitude, which you can use in conjunction with Hypoxico systems. This chart will help you find oxygen levels at altitudes you are interested in, starting with the oxygen content of the air at sea level.

How are people adapted to breathing at high altitudes?

Native Peruvians and Bolivians have adapted their bodies to produce more hemoglobin in their blood, effectively increasing the capacity of their lungs. The Tibetans and Nepalese have adapted to breathe quicker, and also have larger arteries and capillaries to carry blood throughout their body.
