Mr Myers presents a clinical note to the court from June 19, 12 days after Child B was born, noting there were desaturations recorded - if not on the same scale as those recorded during the non-fatal the collapse - and on June 20 when "the apnoea alarm went off" on three occasions, with oxygen saturation "down to 70-80% each occasion".
A paediatric asessment dated July 14 for Child B is presented to the court, in which 'breathing problems' are noted along with 'mottling'.
Mr Myers: "There are some respiratory issues associated with her health?"
Dr Evans: "Nothing compared to what we would call the 'index event' (the collapse). She needed resuscitating."

Mr Myers asks about the non-fatal collapse of Child B, who needed breathing support at birth, as a clinical note shown to the court shows.
An x-ray review has the note 'RDS type picture', as also shown for Child A.
Dr Evans agrees with Mr Myers that a child such as Child B is 'prone to desaturations'.
4:07pm
Mr Myers asks about the differential diagnosis for Child B, concluding there was either an air embolus, suffocation, or someone had removed the prongs on purpose.
Dr Evans said, in his opinion, he was "on the ball from the start" in considering an air embolus.
He said his opinion was reinforced by colour changes "every 10 seconds" as mentioned by a Countess staff member in court.
4:09pm
The theory of removing the CPAP prongs on purpose is discussed.
He says it's possible for a baby to move them by accident.
He is asked if smothering is a possibility, to which Dr Evans says he has since discounted.
4:16pm
Mr Myers said it is a 'key aspect' that the inability to successfully resuscitate Child A had led to an air embolus. He adds that child B recovered, and that is "inconsistent" and "contradicts the air embolus theory".
Dr Evans: "No it does not. We cannot do studies where we inject air into babies and see what happens."
He adds that the volume and speed at which air is injected, along with the skill of the resuscitation attempts, can make a difference as to whether the baby survives or dies.
