What does pulseless electrical activity mean?

Introduction. Pulseless electrical activity (PEA), also known as electromechanical dissociation, is a clinical condition characterized by unresponsiveness and impalpable pulse in the presence of sufficient electrical discharge.

What does pulseless electrical activity look like?

Pulseless electrical activity (PEA) refers to cardiac arrest in which the electrocardiogram shows a heart rhythm that should produce a pulse, but does not. Pulseless electrical activity is found initially in about 55% of people in cardiac arrest.

Why does pulseless electrical activity happen?

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.

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.

What is pulseless electrical activity management?

Treatment / Management

The first step in managing pulseless electrical activity is to begin chest compressions according to the advanced cardiac life support (ACLS) protocol followed by administrating epinephrine every 3 to 5 minutes, while simultaneously looking for any reversible causes.

How is VT diagnosed on ECG?

Frequently, this is difficult to see due to the fast rate of the QRS complex. Below is an ECG strip of a patient with VT. See the PP interval when in sinus rhythm then march out the P waves within the wide QRS complex to find the AV dissociation that is present, confirming the diagnosis of VT.

What is the difference between asystole and pea?

Know 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.

What is meant by the term pulseless electrical activity PEA?

Pulseless electrical activity (PEA) is a clinical condition characterized by unresponsiveness and the lack of a palpable pulse in the presence of organized cardiac electrical activity. Pulseless electrical activity has previously been referred to as electromechanical dissociation (EMD).

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.

What drug is pea?

Epinephrine should be administered in 1-mg doses intravenously/intraosseously (IV/IO) every 3-5 minutes during pulseless electrical activity (PEA) arrest.

Can a person breathe without a pulse?

Without blood, the brain cannot survive. A constant supply of fresh blood is required to keep the brain alive and functioning properly. When blood supply stops, the brain shuts down, including its respiratory center. So, when the heart stops, so does breathing, usually within a minute or less.

How often do you give adenosine?

In light of this adenosine should be administered by RAPID intravenous bolus so that a significant bolus of adenosine reaches the heart before it is metabolized. A change from the 2010 guidelines now has adenosine given up to two times rather than three.
