Whether patients with cerebral infarction need to use ventilator-assisted ventilation needs to be judged according to the condition; in severe cases, they may never be able to get off the ventilator, or they may be able to get off the ventilator after 1-2 days if the condition is controlled in time, depending on the specific condition. If the patient’s brainstem is infarcted, resulting in central respiratory failure, the patient may be brain dead, so the patient needs to use the ventilator for a long time until the patient’s clinical death. If the patient’s cerebral infarction leads to lung infection, which in turn causes respiratory failure, in this case the use of ventilators, as long as the lung infection is controlled, the patient’s body will recover in about 2-4 weeks. If the patient has undergone surgery for cerebral infarction, attempts can be made to wean the patient off the ventilator as soon as he or she regains consciousness.
