Fig. 5

Circulatory and respiratory changes during post-natal transition in a premature case (GA = 30 wk) with respiratory distress syndrome (RDS), in which pulmonary vascular resistance does not fall and ductus arteriosus remains patent. Plots compare transitional dynamics in delayed cord clamping (DCC, solid lines) against immediate cord clamping (ICC, dashed lines). Adverse effect of ICC on early oxygenation is more profound and prolonged due to RDS compared to normal premature birth, as seen in a for CA and PA. Pulmonary flow rate in ICC is lower compared with DCC by 21% as seen in b. Axis ranges are the same as Fig. 3 in order to facilitate comparisons between normal and RDS cases. CA: carotid arteries, PA: pulmonary arteries
