Frequently Asked Questions
Can anyone use a defibrillator?
Yes, AEDs are designed for use by untrained bystanders, with voice prompts guiding you through each step, and they won't deliver a shock unless one is actually needed.
How successful is defibrillation?
Survival rates are around 85% when ventricular fibrillation is treated within the first 3 minutes, which is why speed is so critical in cardiac arrest.
Is it safe to use a defibrillator on someone?
Yes, AEDs are designed to be safe for use by the public and will only advise a shock if the device detects a shockable rhythm.
What happens after a successful shock restores the heartbeat?
The patient is taken to the ICU for close monitoring and treatment of the underlying cause of the arrhythmia.
Can defibrillation be used on someone whose heart has completely stopped?
No, defibrillation only works on specific shockable rhythms like ventricular fibrillation; a fully stopped heart (asystole) requires CPR and medications rather than a shock — emergency responders are trained to recognize the difference.
