How is hyperventilation treated by pilots?

Breathe into a paper bag and control breathing rate is the correct treatment for hyperventilation, particularly in the context of pilots and aviation. Hyperventilation causes a decrease in carbon dioxide levels in the blood, leading to symptoms such as lightheadedness, tingling, and sometimes even loss of consciousness. By breathing into a paper bag, a pilot can increase the concentration of carbon dioxide that they inhale, helping to restore the balance of oxygen and carbon dioxide in their system. This technique also encourages awareness and control of the breathing rate, which is vital in managing hyperventilation.

The other options do not effectively address the physiological imbalance caused by hyperventilation. Increasing the breathing rate would exacerbate the issue, consuming more oxygen and lowering carbon dioxide levels further. Consuming extra oxygen does not solve the underlying problem and can lead to respiratory alkalosis. Physical exercises may also increase breathing rates or oxygen consumption and could potentially worsen hyperventilation symptoms if not carefully managed. Thus, focusing on the paper bag method and controlled breathing is a practical and effective solution for pilots experiencing hyperventilation.
