AED Flashcards
Week 4
What does AED stand for?
Automated external defibrillation
What is the chain of survival?
Early recognition + call for help, early CPR, early defibrillation and post resuscitation care
What is ventricular fibrillation?
What affect to AEDs have on the heart?
AEDs stop fibrillation / stun the heart…
Name the shockable rhythms (where an AED can help)
- ventricular fibrillation
- pulseless ventricular tachycardia
Name the non-shockable rhythms (where an AED cannot help with out other intervention)
- asystole
- pulseless electrical activity
- agonal rhythm
What is biphasic defibrillation?
Literally ‘two phases’ - uses an electrical current that flows in two directions to shock the heart
How likely is defibrillation to be successful after 2 minutes of V-fib?
80% chance of success
How likely is defibrillation to be successful after 4 minutes of V-fib?
60% chance of success
How likely is defibrillation to be successful after 8 minutes of V-fib?
20% chance off success
How likely is defibrillation to be successful after 11 minutes of V-fib?
Virtually 0% chance of success
What can increase / improve the window of opportunity for successful defibrillation?
Good quality CPR

What does ROSC stand for
Restoration of spontaneous circulation
