Ventilator for neonatal pneumonia is mostly used when the pneumonia is severe and accompanied by respiratory failure. The exact number of days to get better will depend on the degree of respiratory failure. If it is mild, it will usually get better in 2~4 weeks, and if it is severe, it will take 4~6 weeks or even longer. Neonatal pneumonia is a serious condition and if left untreated may lead to respiratory failure and other conditions. If the respiratory failure is mild, it usually improves slowly after about 2~4 weeks on the ventilator. If the baby is born prematurely and the neonatal pneumonia is accompanied by severe respiratory failure, the time on the ventilator will be relatively long, taking 4-6 weeks or even a long time. There are individual differences in the duration of treatment for neonatal pneumonia. Parents should not rush their newborns off the ventilator during the treatment process, and need to actively cooperate with the doctor and follow the doctor’s instructions.
