Episode notes
Modern Death Has Two Definitions
- Our traditional view of death was simple: no heartbeat and no breathing.
- Modern technology, like ventilators, forced the medical field to define brain death as a new death type.
Perfusionist’s Deep Freeze Surgery Story
- Adam Richman described performing deep hypothermic circulatory arrest during heart surgeries.
- This cools the body so deeply the brain flatlines, yet patients are kept alive by machines.

- In deep hypothermic circulatory arrest, the patient's brain and heart stop, but their life is sustained externally.
- This challenges simple binary definitions of alive or dead since their body functions extremely slowed but is maintained.
