What is a common symptom of hyperventilation that pilots may experience?

Tingling sensations are a common symptom of hyperventilation that pilots may experience due to the decrease in carbon dioxide levels in the blood. When a person hyperventilates, they breathe too quickly or deeply, which can lead to respiratory alkalosis. This condition causes a decrease in carbon dioxide concentration, resulting in various symptoms, including the tingling or numbness in the extremities, face, or around the mouth.

Understanding this symptom is crucial for pilots, as it can manifest during stressful situations or in response to altitude changes, potentially distracting them from their flying duties and impairing decision-making. Recognizing this symptom can help pilots manage their breathing and mitigate the effects of hyperventilation before it leads to more severe problems.
