"When it did begin, the procedure itself went mostly as planned. With the help of two nurses employed by Alcor, the company’s emergency medical technician, Aaron Drake, performed a series of steps designed to keep the blood vessels in Kim’s brain from collapsing.
He connected her to a CPR device to restore the circulation of her blood. A tube was inserted into her lungs to deliver air. She was given medications to prevent the brain from swelling and to break up blood clots. Then she was lowered into an ice bath and carried to the van for the short drive to Alcor’s facility.
By late morning, her head had been separated from her torso. Josh watched from an observation window as the cryoprotectant was pumped through her main cerebral arteries.
When all that remained was to continue the cooling with liquid nitrogen gas, Josh looked into her face for the last time. They had done, he thought, the best they could."
