Why not shock a PEA Arrest? In a PEA arrest, similar to Asystole, the heart doesn’t have the means to use the shock you’re sending it because the primary cause has yet to be corrected. Shocking a heart in PEA arrest is like kicking a comatose patient in the abdomen (which we do not recommend).
What happens if you shock a PEA?
In PEA, there is electrical activity but insufficient cardiac output to generate a pulse and supply blood to the organs, whether the heart itself is failing to contract or otherwise.

Can you defibrillate PEA?
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.
Why can you not shock asystole?
The Advanced Life Support guidelines do not recommend defibrillation in asystole. They consider shocks to confer no benefit, and go further claiming that they can cause cardiac damage; something not really founder in the evidence.
What are the 3 shockable rhythms?
What are the Shockable Rhythms?
- Asystole, seen as a flat line on an ECG monitor.
- Pulseless electrical activity, or PEA.
Can you come back from PEA?
Can You Survive PEA? Yes, you or your patient can survive PEA if you eliminate the primary cause of the PEA arrest to return the heart to a shockable rhythm. Then resume actions according to the ACLS cardiac arrest algorithm.
What are not shockable rhythms?
Non- shockable rhythms include asystole and pulseless electrical activity. Shockable rhythms include ventricular fibrillation and pulseless ventricular tachycardia. The ECG algorithm (at end of document) can help you determine the proper steps.
Do you shock pulseless v fib?
Pulseless ventricular tachycardia and ventricular fibrillation are treated with unsynchronized shocks, also referred to as defibrillation. If a patient develops ventricular fibrillation during synchronized cardioversion with a monophasic defibrillator, pulselessness should be verified.
How do you treat PEA in ACLS?
When treating PEA, epinephrine can be given as soon as possible but its administration should not delay the initiation or continuation of CPR. High-quality CPR should be administered while giving epinephrine, and after the initial dose, epinephrine is given every 3-5 minutes.
What is the difference between PEA and asystole?
Asystole is the flatline reading where all electrical activity within the heart ceases. PEA, on the other hand, may include randomized, fibrillation-like activity, but it does not rise to the level of actual fibrillation.
Why do doctors hit the chest before CPR?
Procedure. In a precordial thump, a provider strikes at the middle of a person’s sternum with the ulnar aspect of the fist. The intent is to interrupt a potentially life-threatening rhythm. The thump is thought to produce an electrical depolarization of 2 to 5 joules.
What are the 5 lethal rhythms?
You will learn about Premature Ventricular Contractions, Ventricular Tachycardia, Ventricular Fibrillation, Pulseless Electrical Activity, Agonal Rhythms, and Asystole. You will learn how to detect the warning signs of these rhythms, how to quickly interpret the rhythm, and to prioritize your nursing interventions.
Can you do CPR on asystole?
Asystole is treated by cardiopulmonary resuscitation (CPR) combined with an intravenous vasopressor such as epinephrine (a.k.a. adrenaline).
What is the difference between pulseless VT and PEA?
Pulseless electrical activity (PEA) and asystole are related cardiac rhythms in that they are both life-threatening and unshockable cardiac rhythms.
Rules for PEA and Asystole.
| PEA Regularity | Any rhythm including a flat line (asystole). |
|---|---|
| Rate | Any rate or no rate. |
| P Wave | Possible P wave or none detectable. |
Why should an AED not be used in a patient with a pulse?
An AED’s electrical shock must be applied to the patient’s heart. The electrical shock would be transmitted through the water on the chest rather than through the victim’s body if there is water on the chest. Since electrical activity follows the path of least resistance, this happens.
Which drug is considered first line treatment for asystole or PEA?
The only two drugs recommended or acceptable by the American Heart Association (AHA) for adults in asystole are epinephrine and vasopressin. Atropine is no longer recommended for young children and infants since 2005, and for adults since 2010 for pulseless electrical activity (PEA) and asystole.
Has anyone survived asystole?
Overall the prognosis is poor, and the survival is even poorer if there is asystole after resuscitation. Data indicate that less than 2% of people with asystole survive. Recent studies do document improved outcomes, but many continue to have residual neurological deficits.
Can you defibrillate a stopped heart?
Defibrillators are devices that send an electric pulse or shock to the heart to restore a normal heartbeat. They are used to prevent or correct an arrhythmia, an uneven heartbeat that is too slow or too fast. If the heart suddenly stops, defibrillators can also help it beat again.
Is pulseless electrical activity fatal?
Patients who have sudden cardiac arrest due to pulseless electrical activity have a poor outcome. In one study of 150 such patients, 23% were resuscitated and survived until hospital admission; only 11% survived until hospital discharge.
What are the 2 shockable rhythms?
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.
Will an AED shock with a pulse?
An AED will automatically analyse the heart rhythm of a pulse less victim and, if the victim is in ventricular fibrillation (VF) or ventricular tachycardia (VT), shock the victim’s heart in an attempt to restore its rhythm to normal. AEDs will not shock patients who do not require a shock.
