Ms Williams is being talked through her nursing note from the morning of February 17, 2016, in which she described Child K being born in 'fair condition'.
She was 'intubated at approx 12 minutes of age with size 2 ETT'.
Ventilation commenced, and a 'high leak noted'. Ms Williams said that is noted via the ventilator, and if there are any concerns, they are highlighted to the medical team.
She says that can sometimes be down to the size of the ET tube.
Staff would be alerted to the leak via the ventilator giving off an alarm, the court hears.

Ms Williams says there were no concerns over the leak, as the overall clinical picture for Child K was stable.
Ms Williams says the alarms would go off if the baby's clinical picture declined, such as the heart rate dropping or oxygen desaturation. Initially it would be a 'soft alarm', which is amber and makes a noise, then a more urgent alarm in red and 'more of an alerting' sound.
There is a way to pause the alarms, Ms Williams says. That could be paused for several minutes, once it had been activated, in the event of doing a procedure.
Ms Williams says she cannot recall if the alarm could be disabled in advance. The court hears a newer version of the monitors have since been installed in the hospital, where that is possible.
10:45am
Ms Williams says at the time of the 'high leak', the clinical picture for Child K would have been assessed, and a check the tube was in the right place at the mouth.
The prosecution is now asking about the time period when Ms Williams left the nursery room to inform the family on what had been happening.
She said she would not have done so if Child K was not satisfactorily stable.
She tells the court, other than being born very premature, there was nothing of concern.
She does not remember asking anyone in particular to look after Child K in her absence.
