Patients who are angry, sometimes shouting, are often accompanied by hyperventilation, which manifests itself as chest tightness and thus breathing heavily, with fast and frequent breathing leading to excessive carbon dioxide discharge from the body and a significant decrease in the carbon dioxide content in the blood causing numbness in the body, with perioral numbness and numbness in the limbs being the most common. Sometimes it is also accompanied by stiffness and slight shaking of the limbs. If the symptoms of hyperventilation are not relieved, the attack can last from tens of minutes to several hours. The treatment is relatively simple. A paper bag can be used to cover the patient’s mouth and nose so that the exhaled carbon dioxide can be reabsorbed into the lungs, which can bring back the carbon dioxide concentration and quickly relieve the symptoms.
