The most likely causes of secondary PEA are: Blood loss or low blood pressure. Low oxygen levels. Dehydration or other electrolyte problems.
What are the 6 causes of PEA?
They are hypoxia, hypovolemia, hypothermia, hyper/hypokalemia, hydrogen ion (acidosis), tension pneumothorax, tamponade (cardiac), toxins, and thrombosis (cardiac/pulmonary).
What are the two most common causes of PEA?
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. If the individual has a return of spontaneous circulation (ROSC), proceed to post-cardiac arrest care.
What is a possible reversible causes of a PEA rhythm?
Regardless, the most common reversible causes of PEA include hypovolemia, pump failure, and obstruction to circulation, such as choking or even trauma.
When pulseless electrical activity occurs there is?
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.

WHAT DOES PEA stand for?
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 is PEA?
The pea is most commonly the small spherical seed or the seed-pod of the pod fruit Pisum sativum. Each pod contains several peas, which can be green or yellow. Botanically, pea pods are fruit, since they contain seeds and develop from the ovary of a (pea) flower.
What is PEA and how is it treated?
PEA, pulseless electrical activity is defined as any organized rhythm without a palpable pulse and is the most common rhythm present after defibrillation. PEA along with asystole make up half of the Cardiac Arrest Algorithm with VF and VT consisting of the other half. Patients with PEA usually have poor outcomes.
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.
What are the 5 H’s and T’s?
Rapidly identify and treat causes of non-shockable arrest (PEA, asystole). Important causes include the 5 H’s and 5 T’s: Hypoxia, Hypovolemia, Hydrogen ions (acidosis), Hyper/Hypo-kalemia, Hypothermia; Tension pneumothorax, Tamponade-cardiac, Toxins, Thrombosis-coronary (MI), Thrombosis-pulmonary (PE).
Can hypotension cause PEA?
Transient coronary occlusion usually does not cause PEA, unless hypotension or other arrhythmias are involved. Hypoxia secondary to respiratory failure is probably the most common cause of PEA, with respiratory insufficiency accompanying 40-50% of PEA cases.
Is there heart rate in pulseless electrical activity?
Pulseless electrical activity frequently manifests as a very slow QRS complex with heart rates less than 40 beats per minute. Treatment includes emergency initiation of Advanced Cardiac Life Support (ACLS) protocols, which include treatment aimed at the etiology, if identifiable.
What happens in pea?
Pulseless electrical activity (PEA) is a type of irregular heart rhythm, meaning it’s a malfunction of your heart’s electrical system. When this happens, your heart’s electrical activity is too weak to make your heart pump, which causes your heart to stop (cardiac arrest).
How many types of pea are there?
PeaLower classificationsThere are basically three types of peas: English peas, snow peas, and sugar snap peas. Each goes by multiple names, making the choice all the more confusing. But once you get the differences clear, you will probably want to grow some of each. Here are the three main types of peas to grow in your garden.
How can you identify a pulseless electrical activity on an ECG?
Step 1: Determine if the PEA is narrow (QRS duration
What is happening to the heart during pulseless ventricular tachycardia?
Pulseless ventricular tachycardia is a life-threatening cardiac arrhythmia in which coordinated ventricular contractions are replaced by very rapid but ineffective contractions, leading to insufficient organ perfusion and heart failure.
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.
What is asystole PEA?
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 does hypoxia cause PEA?
PEA is always caused by a profound cardiovascular insult (eg, severe prolonged hypoxia or acidosis or extreme hypovolemia or flow-restricting pulmonary embolus). The initial insult weakens cardiac contraction, and this situation is exacerbated by worsening acidosis, hypoxia, and increasing vagal tone.
What causes people to code H’s and T’s?
The H’s and T’s of ACLS is a mnemonic used to help recall the major contributing factors to pulseless arrest including PEA, Asystole, Ventricular Fibrillation, and Ventricular Tachycardia.
