What is the primary action to take to mitigate hyperventilation?

Utilizing controlled breathing techniques is the most effective way to mitigate hyperventilation. Hyperventilation occurs when a person breathes excessively, often leading to a rapid decrease in carbon dioxide levels in the blood, which can result in dizziness, tingling sensations, and shortness of breath. By employing controlled breathing, the individual can slow down their respiratory rate and reestablish a balanced level of carbon dioxide, alleviating the symptoms of hyperventilation.

Controlled breathing techniques typically involve taking longer, deeper breaths at a steady pace, which helps restore the natural rhythm of breathing and stabilize the body's respiratory function. This approach directly addresses the physiological changes caused by hyperventilation.

In contrast, rapid descent may temporarily alleviate certain altitude-related issues but does not specifically target hyperventilation itself. Increasing cabin temperature and using visual distractions do not effectively address the underlying cause of hyperventilation and may not provide the relief needed to restore normal breathing patterns. By focusing on controlling breath, the individual can regain composure and improve their overall situation more effectively.
