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 is the most common cause 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.
Which of the following is possible reversible causes of a PEA rhythm quizlet?
Hypovolemia and hypoxia are the 2 most common underlying and potentially reversible causes of PEA.
How can you identify a pulseless electrical activity on an ECG?
Step 1: Determine if the PEA is narrow (QRS duration
Does cardiac tamponade cause PEA?
Common causes of PEA are cardiac tamponade, dynamic lung hyperinflation, tension pneumothorax, and coronary artery graft occlusion or dehiscence. Severe hypovolemia due to blood loss (e.g., into the chest) may also manifest as PEA (Table 20-9).
What is PEA in CPR?
What Is PEA Arrest? Pulseless electrical activity (PEA) is also known as electromechanical dissociation. It’s a clinical condition in which a patient experiences unresponsiveness in conjunction with a pulse that cannot be felt even when applying sufficient electrical discharge.
What are the two 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.
What are reversible causes of PEA?
Reversible Causes
Hypovolemia and hypoxia are easily reversed and are the two most common causes of PEA.
Which is a possible cause of PEA quizlet?
The two most common causes of PEA are hypovolemia and hypoxia.
What are the most common causes of asystole quizlet?
Asystole is a condition in which there is no electrical activity in the heart. Resuscitation should be immediate. Causes include hypovolemia, hypoxia, acidosis, and potassium imbalances.
Can asystole be reversed?
Treating the underlying problem.
When asystole happens because of an underlying problem, such as an electrolyte imbalance or hypothermia, treating that problem is key. In many cases, remedying that underlying problem will help restart the heart and return it to a normal rhythm.
Which drug is considered first line treatment for asystole or PEA?
Atropine is inexpensive, easy to administer, and has few side effects and therefore can be considered for asystole or PEA. The recommended dose of atropine for cardiac arrest is 1 mg IV, which can be repeated every 3 to 5 minutes (maximum total of 3 doses or 3 mg) if asystole persists (Class Indeterminate).
Can a tension pneumothorax cause PEA?
The presence of PEA in the setting of trauma makes hemorrhage (hypovolemia), tension pneumothorax, and cardiac tamponade the more likely causes.
Can PEA cause sinus tachycardia?
Rhythms in these settings are usually tachycardic–predominantly sinus tachycardia or atrial fibrillation with rapid ventricular response. Patients with PEA are invariably gravely ill. The causes of this dysrhythmia are numerous, spanning all of acute care medicine.
What happens during PEA?
True PEA represents a more severe pathophysiology in which there is a complete absence of mechanical contractions—a true uncoupling of cardiac mechanical activity from the cardiac rhythm. Unlike the reduced aortic pressures of pseudo-PEA, true PEA is characterized by the absence of any aortic pulse pressures.
What is PEA code?
PEA is the abbreviation for a type of cardiac arrest known as pulseless electrical activity. PEA is an organized rhythm without a pulse where the electrical activity of the heart may appear normal, but the heart muscle is not responding. Performing high quality CPR is the initial treatment for PEA.
Can you recover from PEA?
Recent studies have shown that 5.8–6.8% of PEA patients are alive 30 days after resuscitation[7, 11]. The long-term outcome of patients resuscitated from PEA is unknown, whereas the long-term outcome of patients with VF as initial rhythm is well documented[12].
What are the 2 non shockable rhythms?
There are two types of nonshockable rhythms, pulseless electrical activity (PEA) and asystole.
Is PEA a shockable rhythm?
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 happens if you shock 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.

What are the H’s associated with PEA?
These H’s and T’s will most commonly be associated with PEA, but they will help direct your search for underlying causes to any of arrhythmias associated with ACLS. Each is discussed more thoroughly below. Hypovolemia, Hypoxia, Hydrogen ion (acidosis), Hyper-/hypokalemia, Hypoglycemia, Hypothermia.
