Crying to convulsions occurs because the patient is crying and a large amount of carbon dioxide is expelled from the body with respiratory movements, resulting in a decrease in the partial pressure of carbon dioxide in the blood and consequently respiratory alkalosis. The fundamental remedy is to reduce the continued expulsion of carbon dioxide in order to raise the partial pressure of carbon dioxide in the blood. Clinically, a respiratory mask or a container with holes can be placed on the patient’s face to artificially increase the ineffective lumen of the respiratory tract and reduce the exhalation and loss of carbon dioxide, while at the same time facilitating the re-inhalation of carbon dioxide. Generally, disposable paper cups used in daily life can be chosen, and the bottom of the cup can be perforated and then used. Sedative medications can also be used to improve shortness of breath and to prevent or treat convulsions. In addition, intravenous calcium supplementation can be used to increase the calcium concentration in the patient’s blood to improve the symptoms of tics.
