Coarse Ventricular Fibrillation.
The ventricles are no longer contracting but only fibrillation or quivering. There is no blood flow due to no ventricular contraction. If CPR and ACLS protocols are not initiated, coarse VF will progress to fine VF, then to Asystole.
Follow AHA ACLS 2016 Guidelines. High quality CPR with immediate Defibrillatory shock is recommended.
Biphasic Defibrillators: 120 - 200 Joules or recommended. Monophasic Defibrillators: 360 J (followed by 2 mins. CPR). Other secondary interventions can be started if IV/IO access has been established.
INTERVENTIONS:
- Epinephrine 1mg IVP/IO (1:10,000) every 3-5 mins.
- Amiodarone 300mg IVP/IO for the 1st dose; 150mg IVP/IO for the 2nd dose
- Lidocaine 1-1.5mg/kg IVP/IO 1st dose; 0.5-0.75mg/kg 2nd dose
- Correct possible causes
