A remote pilot begins to feel lightheaded, tingly, and anxious after an unexpected stressful event during a flight, and suspects hyperventilation. According to the remote pilot study guide, what is the recommended treatment?

Why: The study guide states that hyperventilation's treatment "involves restoring the proper carbon dioxide level in the body," and that "breathing normally is both the best prevention and the best cure." Slowing the breathing rate — along with techniques like breathing into a paper bag or talking aloud — allows carbon dioxide levels to return to normal, and recovery is usually rapid.

• Hyperventilation is caused by an excessive rate and depth of breathing in the first place; breathing faster and deeper would worsen the excessive loss of carbon dioxide, not correct it.
• The study guide recommends talking aloud as one way to help recovery, the opposite of staying silent; lying down and staying quiet is not the described treatment.
