Aim: Approximately 5% of newborns receive positive pressure ventilation (PPV) for successful transition.
Guidelines urge providers to ensure effective PPV for 30–60 s before considering chest compressions and
intravenous therapy. Pauses in this initial PPV may delay recovery of spontaneous respiration. The aim
was to find the ventilation fraction during the first 30 s of PPV in non-breathing babies.
Methods: Prospective observational study in two hospitals in Norway. All newborns receiving PPV imme-
diately after delivery were included. Cameras with motion detectors were installed at every resuscitation
bay capturing both expected and unexpected compromised newborns. We determined the cumulative
number of seconds with PPV efforts excluding pauses in infants without spontaneous breathing and
reported ventilation fraction during the first minute. Data are presented as median (IQR).
Results: 110 of 3508 (3%) newborns received PPV and were filmed in the resuscitation bays. PPV started
42 (18–78) s after arrival at the resuscitation bay and median duration was 100 (35–225) s. Forty-eight
infants (44%) were ventilated continuously, or with minimal pause (ventilation fraction >90%) during the
first 30 s of PPV. For the remaining 62 infants ventilation fraction was 60% (39–75). PPV was interrupted
due to adjustments, checking heart rate, stimulation, administration of CPAP and suctioning.
Conclusion: In 56% of the neonatal resuscitations interruptions in ventilation are frequent with 60% ven-
tilation fraction during the first 30 s of PPV. Eliminating disruption for improved quality of PPV delivery
should be emphasized when training newborn resuscitation providers.

This
transition is uncomplicated for most infants, however approxi-
mately 5% receive ventilatory support to facilitate liquid movement
out of the airways.

Most depressed neonates respond to applied
positive end-expiratory pressure or positive pressure ventila-
tion (PPV) to increase functional residual capacity.

International
guidelines in neonatal resuscitation recommend providers ensure
effective PPV for at least 30 s before considering chest compressions
and intravenous therapy.

Video recordings have been suggested to be a valuable tool to
evaluate resuscitation performance and outcome during neona-
tal resuscitations.

Difficulties with mask leak, head position,
obstructed airways or inappropriate airway pressures have been
reported even when highly experienced and skilled neonatolo-
gists resuscitate infants.
