Fig 3 — (A) Arterial saturation of oxygen measured by pulse oximetry (SpO₂), (B) cerebral oxygenation (SctO₂), (C) cerebral blood flow (CBF), (D) cerebral oxygen extraction (COE), (E) arterial pressure measured in a carotid artery (P_CA) and (F) heart rate measured in Vent 1^st (closed circles) and Clamp 1^st (open circles) preterm lambs. First dashed line indicates ventilation onset for Vent 1^st lambs or umbilical cord clamping for Clamp 1^st lambs; second dashed line indicates umbilical cord clamping for Vent 1^st lambs and ventilation onset for Clamp 1^st lambs. F = fetal value. * indicates significant difference Vent 1^st vs. Clamp 1^st (p<0.05). # indicates time difference from fetal (F) value (p<0.05). In the time between umbilical cord clamping and ventilation onset, Clamp 1^st lambs significantly reduced arterial and cerebral oxygen saturation, and increased CBF and oxygen extraction to compensate. Ventilation onset increased arterial and cerebral oxygen saturation back to Vent 1^st lambs values by 5 min. Vent 1^st lambs maintained steady oxygenation and haemodynamics during the same time.
