The trial is resuming following its lunch break.
The judge describes Prof Sally Kinsey's evidence, in which she had concluded, from the descriptions by dctors and nurses of skin discolouration, that Child A had had an air embolus. The court had been told of how an air embolus affects the body. She confirmed she had not seen one in her experience, but the descriptions provided were "pretty stark".

The judge turns to the case of Child B, and relays the care and events leading up to and the time of her collapse.
2:22pm
A nurse colleague said she had her gloves on, and was drawing up medication, when Child B collapsed at 12.30am. Letby had said Child B was apnoeic [not breathing].
The nurse said Child B 'looked like Child A', with blotchy discolouration; a 'cyanosed appearance' was recorded in the nursing notes. The notes added the colour changed rapidly, to "purple blotches with white patches."
Letby said she had accepted being in room 1 at the time of the collapse. She said the colleague had alerted her to Child B's collapse. Child B had a 'dark mottling', a 'general mottling'. Child B was 'more purple' and she did not see what the nursing colleague had seen.
Letby had accepted she would have had access to the IV lines prior to the collapses of Child A and Child B, but said she did not do anything with them.
Letby, in police interview, said Child B's mottling 'purple, red, rash-like appearance' was more extensive than with Child A, but was "similar".
She recalled Child A and Child B's parents being very upset. She said, in a 2019 police interview, she accepted she may have taken blood gas readings prior to the collapse, but did not do anything to harm Child B. In a 2020 police interview, she said she did not know how Child B collapsed.
2:27pm
Dr Rachel Lambie said the most unusual observation for Child B was a 'dusky, pale grey colour - then developing widespread blotches of a purple/red colour - they would flush up, then disappear, then appear elsewhere - they were flitting all over'.
It took about 90 minutes for the grey colour to disappear and be replaced by pink, she added.
She said this "was a very unusual event" which she had not seen before or since, and Child B recovered quickly.
Blood gas results came back as normal.
Letby said she had been asked to get a camera to get a photo of Child B, but when she had returned, the discolouration had gone.
A female doctor recalled 'purple blotching to the mid-right abdomen and right hand', which she was "puzzled" by.
The rash was "so florid" and "so very unusual", she said, and its quick disappearance was not normal.
