Fig. 1: Impact of ventilation strategy at birth on carotid blood flow.

Absolute CBF waveform measures including the mean (a; p < 0.0001), minimum (b; p = 0.0007), maximum (c; p < 0.0012) and amplitude (d; p = 0.15) during foetal measures with the cord intact (CI), following cord clamping (CC) before ventilation and 90 min of positive pressure ventilation in the No-RM (black circles), DynPEEP (open circles) and SI (grey diamond) recruitment groups. DynPEEP data represents pooled data for both the 14 and 20 cmH2O maximum PEEP. Foetal period without any ventilation shown in grey background. Birth; first 10 s after commencing allocated recruitment strategy. All p values represent the overall p value using a mixed effects model (time and strategy combined). ^No-RM vs DynPEEP p < 0.05 Tukey post-tests. All data are mean and standard deviation.
