Remembering all the different energy setting needed for synchronized cardioversion and defibrillation used to be confusing for a lot of people. Defibrillators can be broken down into three basic categories: 1.  Automated External Defibrillator (AED); 2.  Biphasic defibrillators; and 3.  Monophasic defibrillators. Use of an AED to rapidly deliver a shock. Advantages & use of Biphasic defibrillators. For monophasic defibrillators, use 360J to defibrillate V-Fib or pulseless V-Tach. AEDs must not be used on patients with a pulse. Cardioversion of patients in unstable SVT or V-Tach with a pulse using biphasic vs monophasic monitor/defibrillators. Team safety when performing synchronized cardioversion. Energy needed to cardiovert unstable patients with a narrow vs wide complex tachycardia.
