See critical care quick reference for defibrillation settings (joules) by weight.
Defibrillation (Unsynchronized cardioversion)
- Supraventricular tachycardia (SVT)
- Atrial fibrillation
- Atrial flutter
- Ventricular tachycardia with a pulse
- Automated External Defibrillator (AED)
- Apply pads or paddles
- Paddles may be slightly quicker but pads are viewed to be safer
- Larger pads reduce transthoracic impedance
- “Adult” size in adults
- “Adult” size (8 to 10 cm) for children >10 kg (> approximately 1 year)
- “Infant” size for infants <10 kg
- 4 accepted pad positions: anterolateral, anteroposterior, anterior-left infrascapular, and anterior-right-infrascapular
- Anteroposterior position performs slightly better
- Biphasic setting
- Defibrillator Refractory VF
