Hyperventilation is common in hysteria. Clinically speaking, it is not a particularly serious disease, mainly due to excessive ventilation and hyperventilation, resulting in excessive carbon dioxide discharge from the body. Its triggering factors are mainly due to the patient’s huge mental stress stimulation, emotional agitation, such as quarrel with others, anger, mania, the emergence of increased respiratory rate, exceeding the normal ventilation function, so that the body’s carbon dioxide is constantly discharged, resulting in respiratory alkalosis. At this time, the patient may have different degrees of respiratory difficulty, appearing lips, limbs, skin numbness, and even accompanied by dizziness, lethargy state. Symptoms can be relieved by gradually increasing the carbon dioxide concentration in the body through measures to suppress hyperventilation.
