Hyperventilation occurs when crying, and this time is most often clinically associated with hyperventilation due to hysteria, which causes respiratory alkalosis and respiratory dysfunction. Patients should be allowed to stabilize their emotions, take appropriate bed rest, and maintain a stable state of mind. You can also choose an easy way to relieve it by covering the mouth and nasal cavity with a sterile plastic bag for proper breathing, which can replenish a certain amount of carbon dioxide to the body and reduce the entry of excessive oxygen, which can properly correct respiratory alkalosis. And you can also give some sedatives, such as Valium. If there is obvious alkalosis, arginine and energy combination can be given appropriately to correct the alkalosis and adjust the treatment plan at any time.
