Why are altitude sickness risks significant for air evacuation?

Altitude sickness risks are significant for air evacuation primarily because hypoxia can occur at higher altitudes. When flying at elevated altitudes, the air pressure decreases, which leads to a reduction in the amount of oxygen available. This reduced oxygen availability can cause hypoxia, a condition where the body or a region of the body is deprived of adequate oxygen supply. For individuals who are already ill or injured, or who might have preexisting health conditions, the development of hypoxia can exacerbate their condition, making effective and safe air evacuation more complicated.

Understanding this risk is critical for transport and medical teams during air evacuations, as they must be prepared to manage the effects of altitude on patients, ensuring they receive the necessary supplemental oxygen or other interventions to prevent complications.
