Leak and obstruction with mask ventilation during simulated neonatal resuscitation

Objectives To evaluate mask technique during simulated neonatal resuscitation and test the effectiveness of training in optimal mask handling. Study design Seventy participants(consultants, registrars and nurses) from neonatal units were asked to administer positive pressure ventilation at a flow of 8 l/min and a frequency of 40–60/min to a modified leak free, term newborn manikin (lung compliance 0.5 ml/cm H2O) using a Neopuff T-piece device. Recordings were made (1) before training, (2) after training in mask handling and (3) 3 weeks later. Leak was calculated. Obstruction (tidal volume
