Question

A pre-hospital team is managing a 55-year-old male who has been in VF cardiac arrest for 30 minutes. He has received 6 shocks, adrenaline every 3-5 minutes, amiodarone 300 mg after the 3rd shock and 150 mg after the 5th shock. VF persists. The team considers double sequential external defibrillation (DSED). How is DSED performed?

Accepted Answer

Two defibrillators are applied with pads in different vectors (standard anterolateral PLUS anteroposterior); both defibrillators deliver near-simultaneous shocks to maximise transmyocardial current

Answer

Three defibrillators are used simultaneously

Answer

One defibrillator shocks while the other monitors rhythm

Answer

Both defibrillators are placed in the same anterolateral position

Answer

A single defibrillator delivers two shocks 1 minute apart
