Mother miraculously survives 45 minutes without a pulse

A Florida mother has finally been released from hospital after giving birth to her newborn a month and miraculously surviving without a pulse for 45 minutes following complications from a routine cesarean section.

Ruby Graupera-Cassimiro, 40, survived after spending 45 minutes without a pulse and enduring three hours of attempts to bring her back from near-death on Sept. 23.

A team of medical workers at Boca Raton Regional Hospital in Florida spent three hours attempting to revive 40-year-old Rudy Graupera-Cassimiro after a rare amniotic fluid embolism. 

Doctors were on the verge of declaring her dead when suddenly there was a blip her heart monitor. That was followed by another and another.

"She spontaneously resuscitated," Boca Raton Regional Hospital spokesman Thomas Chakurda told ABC News. "We had brought the family in. We had announced to them that we had done all we could."

A day later, Graupera-Cassimiro was taken off of life support. And today she is "the picture of health," Chakurda said.

Doctors think she had a rare condition called an amniotic fluid embolism, which is what happens when the amniotic fluid leaks into the blood stream, causes blood clots and leads to cardiac arrest, according to Mayo Clinic.

"It's normally diagnosed post mortem," Chakurda said.

"In a follow-up with one of the physicians, she looked him dead in the eye and said, 'You don't have to be afraid of dying.'" he said.

"I've never seen a group of people so impacted, if you will, by what they saw," Chakurda added. "They all were very struck."
