The T-piece resuscitator is a mechanical device using airflow to control the pressure limitation. It can provide newborns with constant expiratory positive end pressure and inspiratory peak pressure, which can safely expand the baby’s lung and offer excellent oxygenation. This resuscitation device is an easy-to-use resuscitator that is widely used in the delivery room, neonatal wards, postnatal wards, operating rooms, NICU, and neonate’s transfer.
