Survival time for cerebral infarction pneumonia fever depends on the patient’s specific medical condition. Patients may survive for days to years. Survival time for cerebral infarction combined with lung infection depends on the severity of the lung infection. If a patient has a very severe lung infection that is not treated in a timely manner, or if antibiotics are not effective in making the patient physically better, the lung infection can quickly affect the patient’s life, infectious shock can occur, and the survival time may be shortened to a few days. If the lung infection is well treated, some patients can survive for a long time without even affecting their life expectancy. Patients with cerebral infarction are advised to take care of themselves to avoid lung infection, fever, recurrence of cerebral infarction and aggravation of lung infection. When the above symptoms appear, they should go to the hospital for standardized treatment in time.
