Aim Approximately 20% of newborns infants need respiratory support at birth. This study evaluated whether video‐based education could improve quality of positive pressure ventilation ( PPV ) performed by inexperienced staff during neonatal resuscitation. Methods Fourth‐year medical students were randomly paired and instructed to give PPV to a modified manikin as single‐person resuscitators and as two‐person‐paired resuscitators using either an air cushion rim mask or a round mask before and after watching a self‐instructional video. Airway pressure, gas flow, tidal volume and mask leak were recorded. PPV performance quality was analysed using video recording. Results Mask leak was lower during one‐person ventilation when using the air cushion rim mask (56 ± 16%) compared to the round mask (71 ± 19%). Round mask leak during one‐person ventilation was significantly lower when using the two point top hold in contrast to the ‘o.k.’ rim hold (before training: 63 ± 22% vs. 72 ± 18%, after training: 57 ± 17% vs. 77 ± 12%). Watching a self‐instructional video improved performance quality scores of both correct head positioning, and the quality of airway manoeuvres compared to baseline, however mask leak was not significantly reduced. Conclusion A self‐instructional video significantly improved bag mask PPV performance in inexperienced providers but did not improve mask leak in a model of neonatal resuscitation.
