What is hyperventilation?

Hyperventilation refers to the condition where an individual breathes at an abnormally rapid rate, leading to a decrease in carbon dioxide levels in the blood. This excessive airflow can cause physical symptoms such as dizziness, light-headedness, tingling in the fingers and face, and even shortness of breath. In the context of aviation, hyperventilation can pose risks to a pilot, as it may impair decision-making abilities and lead to decreased performance. Recognizing the signs of hyperventilation is essential for pilots so they can manage their breathing effectively and ensure they remain capable of safely operating the aircraft.
