Outcomes
The primary outcome was the evaluation of whether the intubation rate
was significantly lower for P10 patients than for P5 patients. The
secondary outcomes were compared between the two groups: a) the impact
of PEEP levels on cardiorespiratory parameters over time; b) the
pneumothorax rate, c) enteral feeding intolerance (defined as the need
to stop enteral nutrition due to excessive gastric residual volumes and
abdominal distension); d) the length of stay in the PICUs.
