What separates the living from the dead? A heart beat or a pulse may be the vital signs that spring to mind, which suggests that a person is dead when their heart stops beating. However, new research shows that the natural process of death is not so straightforward, and takes us a step closer to understanding the complexity of dying.
Today in The Conversation Canada, Carleton University PhD candidate Amanda van Beinum and University of Ottawa critical care physician Sonny Dhanani and their research colleagues take a closer look at what happens after a monitor shows a heart has stopped beating. After studying hundreds of records of intensive care patients, they found that the classic “flatline” is more complicated than you might think.
Also today:
All the best.
