A connector for resuscitating an infant or neonate is disclosed. The pressure is varied between Peak Inspiratory Pressure (PIP) and Peak End Expiratory Pressure (PEEP) by the occlusion of the PEEP outlet. The PEEP outlet may either allow variable PEEP, by adjustment, or substantially flow independent fixed PEEP using a novel umbrella valve. A duck billed valve is included for suctioning of surfactant delivery during resuscitation. The connector is adapted to one handed use.
