Fig 2. Effect of the timing of ventilation onset relative to umbilical cord clamping.

Representative traces obtained from a lamb in which ventilation was initiated prior to umbilical cord clamping (Vent 1^st), and a lamb in which umbilical cord clamping was conducted prior to the initiation of ventilation (clamp 1^st). Dashed line indicates when an intervention occurred as labeled on the graphs. Note the difference in time scale. SpO₂—arterial oxygen saturation, SctO₂—cerebral oxygenation.
