Heart rate and right ventricular output measured in newborn lambs that either had their umbilical cords clamped 1–2 mins before ventilation was commenced (clamp first; closed circles) or were ventilated and pulmonary blood flow allowed to increase before their cords were clamped (vent first; open circles). The broken line (a) indicates either when cord clamping occurred in the clamp first group or ventilation commenced in the vent first group. The broken line (b), indicates when either clamping occurred in the vent first group or when ventilation commenced in the clamp first group. Data were obtained from [6] and redrawn
