In this episode, we talk to Sheldon Cheskes about the evolving science of cardiac arrest, with a focus on refractory and recurrent ventricular fibrillation. We explore the evidence behind double sequential external defibrillation (DSED), how it compares to standard defibrillation, and what the DOSE VF trial has changed in practice. It’s about understanding why defibrillation fails, how vector and energy delivery matter, and when a different approach might improve outcomes.

Recorded at Trauma 2030 at the Royal College of Surgeons, this episode explores a shift in mindset in pre-hospital trauma care, away from maximal intervention on scene and towards rapid
