V Fib Shockable Rhythm

Monitor the victim s heart rhythm and blood pressure if the patient is in vtach or vfib this is a shockable rhythm apply defibrillator pads or paddles and shock the patient with 120 200 joules on a biphasic defibrillator or 360 joules using a monophasic.

V fib shockable rhythm. The uncoordinated ventricular muscle quivers therefore there is no effective cardiac output. On the monitor v fib will look like a irregular and disorganized wavy line. If the patient shows signs of return of spontaneous circulation or rosc administer post cardiac care. In advanced cardiac life support acls rescuers are trained to recognize a shockable rhythm on the defibrillator screen.

In this blog post we will take a closer look at the two non shockable rhythms. The two shockable rhythms in cardiac arrest are. When acls providers conduct a rhythm check if that rhythm check reveals a shockable rhythm vfib or pulseless v tach they will prepare to deliver a shock while also ensuring the continuation of high quality cpr while the unit is charging and in between shocks. 350 450 bpm irregular this is a shockable rhythm.

It produces no effective myocardial contraction. Non shockable means that defibrillation is not an effective treatment for these heart rhythms. Ventricular fibrillation and pulseless ventricular tachycardia are treated using the left branch of the cardiac arrest arrest algorithm. Pulseless ventricular tachycardia is a rhythm that is perfusing poorly with patients may or may not be displaying a pulse.

Cpr 2 min. If an automated external defibrillator aed detects a shockable rhythm is will recommend the rescuer delivers an electrical shock to the victim. Check for pulse and rhythm for no more than 10 seconds every 2 minutes. Ventricular fibrillation may be fine or coarse.

Vf and pulseless vt are shockable rhythms and treated in similar fashion. However if the rhythm is asystole defibrillation will be ineffective. Fine v fib is sometimes mistaken for asystole. Asystole and pea are also included in the cardiac arrest algorithm but are non shockable rhythms.

Ventricular fibrillation vf. As the treatments for asystole and ventricular fibrillation are different it is important to differentiate between the two. If in doubt it is acceptable to deliver a shock. Description ventricular fibrillation is when the ventricles of the heart are quivering at a rate of 350 to 450 beats per minute irregularly.

Coarse ventricular fibrillation is more likely to convert after defibrillation than fine v fib. A non shockable rhythm displayed on the right side of the algorithm. This essentially causes no blood to be pumped to the lungs systemic tissues or to the brain. If it is fine v fib you may terminate the rhythm.

If an automated external defibrillator aed detects a non shockable rhythm it won t allow the rescuer to deliver an electrical shock to.
