To reduce airway injury secondary to high suction pressures, the American Academy of Pediatrics Neonatal Resuscitation Program (NPR) recommends that suction pressures be less than 100mm Hg. This study was conducted to determine if suction bulbs conform to these recommendations.In this prospective in vitro study, 25 personnel involved in neonatal resuscitation squeezed a new bulb three times for each of six commercially available bulbs using their delivery suite technique. A calibrated, pneumatic transducer measured the pressure of each squeeze.Only one bulb met the NRP guidelines with none of the participants exceeding 100mm Hg (p<0.001).Only one bulb met the NRP guidelines of generating pressures less than 100mm Hg. This bulb's large size (3oz) may preclude its use in premature infants. Individuals involved in resuscitating newborns need to be aware of the pressures generated to avoid injuring the delicate oral airway.
