Hypoxia is a major concern at high altitudes and can lead to symptoms such as fatigue, decreased cognitive function, and impaired judgment. This makes it especially critical for air medical crew to monitor their own physiological status as well as that of their patients. Dehydration and vibration are also possible stressors but are less directly linked to the described symptoms. Temperature fluctuations can cause discomfort and thermal regulation issues, but the primary cause of fatigue and decreased cognitive function is hypoxia.
