What are the 2 most common causes of pulseless electrical activity?

Hypovolemia and hypoxia are the two most common causes of PEA. They are also the most easily reversible and should be at the top of any differential diagnosis.

What can you do for pulseless electrical activity?

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.

What drug do you give for pulseless electrical activity?

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

What is a typical cause of pulseless electrical activity?

Various causes of pulseless electrical activity include significant hypoxia, profound acidosis, severe hypovolemia, tension pneumothorax, electrolyte imbalance, drug overdose, sepsis, large myocardial infarction, massive pulmonary embolism, cardiac tamponade, hypoglycemia, hypothermia, and trauma.

What causes Torsades de Pointes?

Common causes for torsades de pointes include drug-induced QT prolongation and less often diarrhea, low serum magnesium, and low serum potassium or congenital long QT syndrome. It can be seen in malnourished individuals and chronic alcoholics, due to a deficiency in potassium and/or magnesium.

Why is a defibrillator used?

AEDs are used to revive someone from sudden cardiac arrest. This usually occurs when a disruption in the heart’s electrical activity causes a dangerously fast heartbeat (ventricular tachycardia) or a fast and irregular heartbeat (ventricular fibrillation).

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 is the most appropriate treatment for PEA?

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 are the most common causes of PEA?

Hypoxia secondary to respiratory failure is probably the most common cause of PEA, with respiratory insufficiency accompanying 40-50% of PEA cases. Situations that cause sudden changes in preload, afterload, or contractility often result in PEA.

Is torsades de pointes pulseless?

Torsades de pointes is a ventricular tachycardia. In the unstable patient, cardiovert. In the pulseless, defibrillate. (The polymorphic nature of the rhythm may interfere with the defibrillator’s ability to synchronize, so cardioversion may not be possible.

Is torsades VT or VF?

Torsade is defined as the combination of polymorphic ventricular tachycardia plus a prolonged QT-interval. Torsade can be caused by either congenital long-QT syndrome or acquired long-QT syndrome (due to electrolyte abnormalities and/or medications).

Is a defibrillator AC or DC?

Defibrillation is nonsynchronized random administration of shock during a cardiac cycle. In 1956, alternating current (AC) defibrillation was first introduced to treat ventricular fibrillation in humans. Later in 1962, direct current (DC) defibrillation was introduced. See the video below.

What is “pulseless” electrical activity?

Pulseless electrical activity is not a specific rhythm. Instead, it’s a term used to describe any organized electrical activity – but excluding VFib or asystole — on an ECG or cardiac monitor that is associated with no palpable pulses. Pulsations can be detected by an arterial waveform or Doppler study. However, pulses are not palpable.

How is pulseless electrical activity (PEA) diagnosed?

Diagnosis of Pulseless Electrical Activity (PEA) An ECG/EKG is capable of distinguishing pulseless electrical activity from other causes of cardiac arrest. The absence of a patient’s pulse confirms a clinical diagnosis of cardiac arrest.

How do you treat pulseless electrical activity in the hospital?

Treating pulseless electrical activity both inside and outside of the hospital involves the use of Advanced Cardiac Life Support protocols. In order to ensure that you are up-to-date on the latest ACLS guidelines, as well as to comply with your employer’s requirements, you must keep up with ACLS certifications.

How do you check for pulseless electrical activity in ACLS?

ACLS providers should make sure to check for a pulse at the carotid artery. They can also check for heart sounds by using a stethoscope for no more than 10 seconds. Diagnosis of Pulseless Electrical Activity (PEA) An ECG/EKG is capable of distinguishing pulseless electrical activity from other causes of cardiac arrest.
