2:49pm
The nurse said after less than a minute, after realising it was an "acute episode", a crash call would be made to alert doctors.
The nurse recalls, from her notes, Child I was apnoeic, and dusky in appearance."
A Neopuff device was used to provide breathing support with 30% oxygen. 'Neopuff applied due to colour and apnoea.
'Colour didn't improve and [oxygen saturation and heart rate] began to drop rapidly until [oxygen saturation] 47% and [heart rate] 50. Neopuff increased to 50% then 100% with no effect."
Cardiac compressions began, and Child I was placed on a ventilator. Child I had become 'more alert and crying. Abdomen soft and non-distended prior to resuscitation, no change from handover."
Child I was recorded to be fighting the ventilator. The nurse says that was a sign Child I had recovered quite quickly, but keeping the child on the ventilator in that condition could cause lung damage, so a decision was taken to remove her from the ventilator.
Child I was "seemingly displaying normal behaviour despite what had happened" as she was also 'still rooting'.
2:56pm
The nurse says this episode, at about midnight, was a "very quick resuscitation" from her recollection, and no medication needed to be administered.
The court hears Ashleigh Hudson "managed to get through to [Child I's] parents after many attempts" regarding the first resuscitation. She said it was to be expected as it was the middle of the night.
Afterwards, Child I was "seemingly back to normal" with "nothing to cause concern" during that time after the first resuscitation.
Just after 1am, she was near, but not inside, nursery room 1.
3:03pm
The nurse says she was first alerted to Child I desaturating either from an alarm sounding on the monitor or from Child I crying.
Nurse Hudson recalls: "Lucy was already with her [at the incubator], trying to settle her. At that time [Child I's] observations were normal."
She says child I was crying "the same cry I had heard her display the first time [that night].
"Loud and relentless and unlike any other cry I had heard make prior to this night shift."
"My initial concern was she was obviously breathing...my concern was the cry was that she was going to have another episode of collapse."
She recalls articulating that concern to Lucy Letby within 60 seconds of being there.
The nurse says she said words along the lines of: "She's going to do it again, it's the same cry."
Letby responded with words of "reassaurance": "She just needs to settle," Ashleigh Hudson recalls Letby saying.
Child I became quiet, with pauses in breathing, and she became bradycardiac and her saturations "started to drift".
Oxygen delivery began again, along with ventilation breaths. They shouted for help from colleagues.
3:09pm
Nurse Hudson says she does not recall direct further communication with the parents, as the staff were "all in the thick of it" trying to resuscitate Child I.
The court is shown the October 23, 6.25am note by Ashleigh Hudson: "*NGT on free drainage, produced 2mls. Minimal aspirations of clear mucus and air++ during both resuscitations. Green stool and urine present post resus."
The nurse said, given previous abdominal issues for Child I, she had wanted to "make clear" what was observed during those resuscitations.
3:22pm
Ben Myers KC, for Letby's defence, is now asking nurse Ashleigh Hudson questions.
3:25pm
He says the questions he is to ask, while technical, are not for lack of sympathy.
He says that in between the shifts she was looking after Child I, she was aware there had been further arrests and desaturations. Nurse Hudson agrees, and agrees that Child I was "very ill" when she had gone to Arrowe Park Hospital.
He asks if Child I needed to be looked at closely, and "there is always the potential for deterioration".
Nurse Hudson: "Yes."
"She is never completely out of the woods?"
"Yes."
"You can never become complacent."
"That was my view at the time."
3:27pm
Mr Myers says nurse Ashleigh Hudson was in the first 8-9 months of trained care at the time in October 2015, and would not have been intensive trained at this stage.
Ms Hudson says there were certain medical procedures which she would not be trained for at this stage, and it meant when those needed to take place, other staff, such as Lucy Letby, would do them for her.
The trial of Lucy Letby, who denies murdering seven babies at the Countess of Chester Hospital neonatal unit and attempting to murder 10 more, is…
