Energy Settings for Defibrillation & Synchronized Cardioversion

Pass ACLS Tip of the Day

Nov 10 2023 • 5 mins

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.
