Is pulseless electrical activity shockable?

Rhythms that are not amenable to shock include pulseless electrical activity (PEA) and asystole. In these cases, identifying primary causation, performing good CPR, and administering epinephrine are the only tools you have to resuscitate the patient.

Are pulseless rhythms shockable?

VF and pulseless VT are shockable rhythms and treated in similar fashion. Asystole and PEA are also included in the cardiac arrest algorithm but are non-shockable rhythms. Ventricular fibrillation and pulseless ventricular tachycardia are treated using the left branch of the cardiac arrest arrest algorithm.

How is pulseless electrical activity treated?

Treatment for pulseless electrical activity involves high-quality CPR, airway management, IV or IO therapy, and the appropriate medication therapy. The primary medication is 1mg epinephrine 1:10,000 every 3-5 minutes via rapid IV or IO push.

Is PEA and asystole shockable?

Both PEA and asystole remain non shockable rhythms. With that in mind, treating the causes of arrest should lead to a period where the rhythm enters a shockable state.

What are shockable rhythms in the pulseless patient?

The two shockable rhythms are ventricular fibrillation (VF) and pulseless ventricular tachycardia (VT) while the non–shockable rhythms include sinus rhythm (SR), supraventricular tachycardia (SVT), premature ventricualr contraction (PVC), atrial fibrilation (AF) and so on.

What are shockable and non shockable rhythms?

Shockable rhythms include pulseless ventricular tachycardia or ventricular fibrillation. Nonshockable rhythms include pulseless electrical activity or asystole.

What is shockable and non shockable?

The four are divided into two groups: two that do not require defibrillation (called “non- shockable”) and two that do require defibrillation (“shockable”).

Why can you not shock PEA?

Pseudo-PEA is a form of severe shock in which diminished coronary perfusion leads to decreased myocardial function, thus further propagating hypotension. The pathologic insult causing the pseudo-PEA impedes the cardiovascular system’s ability to provide circulation throughout the body.

How does epinephrine help PEA?

Medications used in PEA

The vasopressor that is used for the treatment within the right branch of the Cardiac Arrest Algorithm is epinephrine. Epinephrine is primarily used for its vasoconstrictive effects. Vasoconstriction is important during CPR because it will help increase blood flow to the brain and heart.

What happens during PEA?

Pulseless electrical activity (PEA) occurs when a major cardiovascular, respiratory, or metabolic derangement results in the inability of cardiac muscle to generate sufficient force in response to electrical depolarization.

Is pulseless electrical activity asystole?

Pulseless electrical activity (PEA) and asystole are related cardiac rhythms in that they are both life-threatening and unshockable cardiac rhythms. Asystole is a flat-line ECG (Figure 27). There may be a subtle movement away from baseline (drifting flat-line), but there is no perceptible cardiac electrical activity.

Why is asystole not shockable?

Pulseless electrical activity and asystole or flatlining (3 and 4), in contrast, are non-shockable, so they don’t respond to defibrillation. These rhythms indicate that the heart muscle itself is dysfunctional; it has stopped listening to the orders to contract.

Why are VT and VF shockable?

Shockable rhythms are rhythms that are caused by an aberration in the electrical conduction system of the heart.

Will an AED shock pulseless electrical activity?

Nonshockable Rhythms

As such the AED will not advise shock for these rhythms. There are two types of nonshockable rhythms, pulseless electrical activity (PEA) and asystole.

How do you know if rhythm is shockable?

A shockable rhythm was defined as disorganized rhythm with an amplitude > 0.1 mV or, if organized, at a rate of > or = 180 beats/min. Wavelet-based transformation and shape-based morphology detection were used for rhythm classification.
