The final report into a fatal oxygen mix-up at a western Sydney hospital has found "a series of tragic errors" led to one boy's death and a baby girl's serious injury.
The baby boy died and a newborn girl suffered suspected brain damage after they were mistakenly given nitrous oxide or "laughing gas" instead of oxygen at Bankstown-Lidcombe Hospital in June and July this year.
A report by NSW Chief Health Officer Dr Kerry Chant, released on Saturday, found the incorrect installation of medical gas pipes and flawed testing and commissioning of the pipes led to the two cases.
"This was a catastrophic error and on behalf of NSW Health, I apologise unreservedly to both families," Dr Chant told reporters on Saturday.
