[Efficacy of volume-guaranteed high-frequency oscillatory ventilation in preterm infants with respiratory distress syndrome and its impact on cerebral blood flow in the middle cerebral artery].

HFOV-VG can effectively improve cerebral blood perfusion, reduce cerebrovascular resistance, shorten the durations of mechanical ventilation and hospital stay, and enhance overall treatment efficacy. It has significant advantages in reducing the risk of 28-day mortality, bronchopulmonary dysplasia, and intraventricular hemorrhage in preterm infants with RDS.
