But either you mistold the story, or the paramedics made a mistake: ambulances are not supposed to transport a dead person - the paramedics are first to resuscitate and stabilize the patient, and only then initiate transportation.
(I understand you may not care, because the outcome of their action incidentally was one you like.)
From what I was told, he was born with the umbilical cord wrapped around his throat, and just kind of "fell out" while his birth mother was walking from the bathroom to the living room. I know that part is true, at least, because we saw the apartment floor the next day...
I think probably the paramedics were able to detect some faint vitals upon arrival. Since the birth mother and her partner weren't super reliable or coherent, we weren't really able to piece it all together until we tracked down the two young men who helped save our son's life that night.
He didn't say the baby wasn't breathing when they picked him up. He said the hospital was expecting a DOA - presumably because of the news along the way, before they resuscitated the baby.
