Airway obstruction and gas leak during mask ventilation of preterm infants in the delivery room

Abstract

Introduction: Preterm infants with inadequate breathing receive positive pressure ventilation (PPV) by mask with variable success. The authors examined recordings of PPV given to preterm infants in the delivery room for prevalence of mask leak and airway obstruction. Methods and patients: The authors reviewed recordings of infants at <32 weeks' gestation born between February 2006 and March 2009. PPV was delivered with a T-piece or self-inflating bag and a round silicone face mask. Airway pressures and gas flow were recorded with a respiratory function monitor (RFM). Videos recorded from a web camera were used to review the resuscitation. The first 2 min of PPV were analysed for each infant...
