Human Performance

This is the primary reason why we never dive deeper than 40 meters.

Nitrogen poisoning can also occur when flying at altitude due to the lower

amount of oxygen here.

Nitrogen poisoning can be dangerous because it can impair the pilot's cognitive

and physical functions, which can lead to misjudgments, slower reaction times

and poorer decision-making.

2.6.6.8 Blood donor

Pilots are usually advised against being blood donors.

With your donation, you give away a certain amount of red blood cells.

Normally, this does not matter in everyday life, but as you move up in altitude,

where the pressure is lower, your sensitivity to oxygen deficiency increases.

This causes, for example, a deterioration in the ability to see in the dark.

2.6.6.9 Surgery and open wounds

People who have recently had surgery or have open lesions should not be

exposed to flying, as the pressure may be too much of a strain.
