In the American Journal of Obstetrics and Gynecology, there was an article about a baby who was aborted alive and attached to an artificial placenta. The baby lived for 5 hours.
From the article:
“Irregular gasping movements, twice a minute, occurred in the middle of the experiment, but there was no proper respiration. Once the perfusion was stopped, however, the gasping respiratory efforts increased to 8 to 10 per minute. The fetus died 21 minutes after leaving the circuit.”
