Any change in this balance can cause symptoms to occur. In the process of hyperventilation, breaths are rapid and shallow, causing the carbon dioxide level to drop. Symptoms include light-headedness, giddiness, numbness and tingling of fingers and hands, leading to more anxiety. The immediate treatment involves breathing into a paper bag until the carbon dioxide content of the blood has an opportunity to return to normal. Just as effective is to close one nostril and mouth and breathe slowly through the open nostril.
Treatment continues until symptoms disappear.
Talking to a friend or seeing a counselor will help to relieve anxiety that may cause hyperventilation.
