embolus

One of the issues Dr Lee said the panel had found was that skin discoloration noted on some of the babies was, he claimed, wrongly attributed to air embolus by the prosecution.

An embolus can occur when amniotic fluid gets into the maternal bloodstream.

Continuing his closing speech for a second day, Mr Myers told Manchester Crown Court the "overarching theory of air embolus" was at the "heart" of this case.

She told the court that if the cause of death was established as air embolus, then it would have come from the person connecting the fluids, "which wasn't me".

He also went on to say that Dr Evans did not have any empirical research to back up his claims about the effects of air embolus.
