I think an arterial air embolism would take effect almost immediately, but there is a range in how long and in what volume it could to reach the heart causing the fatal blockage. I think one possible explanation for the series of collapses seen in some cases is that the air reached the heart at different times, which was enough to cause a collapse but not enough to cause death Nd then with every bit more air the problem would increase in severity leading to death. Gathered that from what people on here have said. I think just guessing you could expect the full effect within half n hour of administration. If blood circulates the entire system within a minute in an adult I would guess it would take that much time or less for all of it to get to the heart of a baby. It’s apparently a key feature of air embolism that sudden collapse is expected So presumably it’s effect is immediate upon administration.

Medical expert Dr Dewi Evans suggested Child A's collapse was "consistent with a deliberate injection of air or something else into [Child A]'s circulation a minute or two prior to deterioration," Mr Johnson told the court. Only Letby was present.
Another medical expert said the cause was "not some natural disease process, but a dose of air "deliberately administered".
An independent pathologist described the cause of death was 'unascertained', in that there was nothing in the autopsy that pointed to why Child A had died, but the cause was most likely 'exogenous air administration through the longline or UVC'.
But, by 8.26pm that same day he was "deteriorating rapidly".
He had been handed over to Letby's care less than half an hour earlier.
By 9pm, he had been pronounced dead -
Child C's death was a 'refinement of the theme' Letby had started with Children A & B
Child C was pronounced dead just before 6am on the 14 June 2015.
At thge time, the consultant pathologist gave the cause of death as "widespread hypoxic/ischaemic damage to the heart/myocardium due to lung disease".
Child C's vocal cords were "swollen" - something the prosuection say is a reoccuring feature in this case.

in baby E case there is no allegation of inflicted trauma other than the alleged AE. I believe the blood is brought up by the prosecution because it fits with what they have suggested as a pattern in these cases, that swollen throats are a recurrent feature in them, Presumably linked to the method/s.
what I would like to know is how if it is a recurring feature it can fit within the alleged methods.
THE METHODS Hereford nurse Lucy Letby is alleged to have used to harm babies in her care have been revealed in her trial.
