The designated nurse said Child N was stable and left for a break at about 1am. He would have asked a colleague to look after Child N, but he could not recall whch one.
Letby had two babies to care for, in room 4.
At 1.05am, Child N's oxygen saturation levels fell from 99% to 40%.
"Unusually", fr a baby, he was described as crying and "screaming".
Child N recovered quickly, while the doctor was then called to another emergency.
Medical expert Dr Dewi Evans said he believed the deterioration of Child N "was consistent with some kind of inflicted injury which caused severe pain".
Dr Sandie Bohin said such a profound desaturation followed by a rapid recovery, in the absence of any painful or uncomfortable procedure, suggested an inflicted painful stimulus.
She said – “this is life threatening. He was also noted to be … ‘screaming’ and apparently cried for 30 minutes. This is most unusual. I have never observed a premature neonate to scream.”
The prosecution continues its opening in the trial of Lucy Letby, accused of multiple baby murders at the Countess of Chester Hospital.
