What can be a common symptom of hyperventilation experienced in aviation?

Blurred vision can be a common symptom of hyperventilation experienced in aviation due to the physiological changes that occur when a person hyperventilates. During hyperventilation, a person breathes rapidly and deeply, which leads to a decrease in carbon dioxide levels in the blood. This condition, known as respiratory alkalosis, can cause a range of neurological symptoms, one of which is visual disturbances, including blurred vision.

In the context of aviation, where stress and changes in cabin pressure can exacerbate these symptoms, it is crucial for pilots and passengers to recognize that hyperventilation can affect not only respiratory function but also their visual acuity, potentially impacting their performance or ability to pilot an aircraft safely. Recognizing blurred vision as a symptom can prompt individuals to take actions to restore normal breathing patterns, helping to alleviate the problem effectively.
