Patients with cerebral infarction need to be conscious, breathing well, coughing up sputum on their own, and coughing forcefully before attempting tube sealing. If the patient is not conscious, cannot cough up sputum on his/her own, and the chest CT is reviewed, and the pulmonary exudation is still very serious, and the tube is sealed, the patient’s sputum cannot come out, which will aggravate the lung infection, affect the recovery of the condition, and prolong the hospitalization time. If the patient’s consciousness is restored, autonomous breathing is good, autonomous sputum expectoration is possible, sputum expectoration is strong, etc., combined with the recovery of lung infection, tube sealing can be considered. The patient has a tracheotomy, nursing care is also very important, the need for tracheotomy clean, dry, timely sputum suctioning, diligent turning and patting the back, such as respiratory inactivity, the need for timely replacement of the tracheal tube, and family members need to look after, pay attention to the tracheal tube dislodgement and so on.
