There is a progressive reduction of oxygen per breath the higher the altitude. Every pilot’s reaction to hypoxia is different, according to a the Federal Aviation Administration.

Hypoxemia refers to a reduction in the amount of oxygen in the bloodstream. This means that the level of oxygen falls below the normal range and there is not enough present in the blood.
