What are the symptoms of pulmonary encephalopathy

Pulmonary encephalopathy is clinically characterized by insomnia, restlessness, nocturnal insomnia, daytime sleepiness, also known as day-night inversion, and changes in consciousness, such as apathy, muscle tremors, intermittent convulsions, lethargy, and even coma, as well as weakened or absent tendon reflexes. Pulmonary encephalopathy is mainly caused by patients with chronic obstructive pulmonary disease, showing chronic respiratory failure, accompanied by carbon dioxide retention, a series of symptoms caused by elevated carbon dioxide. For pulmonary encephalopathy, respiratory stimulants are mainly used, and ventilators are used for assisted ventilation when symptoms are severe.
