What does the medical acronym pea mean?
Feb 23, 2020 · WHAT DOES Pea stand for in medical terms? 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. Click to see full answer.
What does pea stand for?
pulseless electrical activity (PEA) continued electrical rhythmicity of the heart in the absence of effective mechanical function; it may be due to uncoupling of ventricular muscle contraction from electrical activity or may be secondary to cardiac damage with respiratory failure and cessation of cardiac venous return.
What does the name Pea mean?
Feb 18, 2020 · 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 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.
What is the treatment for PEA?
Cardiopulmonary resuscitation (CPR) is the first treatment for PEA, while potential underlying causes are identified and treated. The medication epinephrine (aka adrenaline) may be administered.
What causes PEA rhythm?
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.Sep 10, 2019
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.Jul 12, 2019
Is PEA reversible?
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.
How long can PEA last?
Conclusions. Patients with initial PEA have been considered to have poor prognosis, but in our material, half of those who survived to hospital discharge were still alive after 5 years. Their self-assessed quality of life seems to be good with only mild to moderate impairments in activities of daily life.Oct 30, 2012
Is asystole and PEA the same?
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.Jan 27, 2020

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).Nov 28, 2005
What drugs are used in PEA?
Inotropic, anticholinergic, and alkalinizing agents are used in the treatment of pulseless electrical activity (PEA). As previously stated, resuscitative pharmacology includes epinephrine and atropine.Mar 27, 2018
What are the 5 lethal rhythms?
You will learn about Premature Ventricular Contractions, Ventricular Tachycardia, Ventricular Fibrillation, Pulseless Electrical Activity, Agonal Rhythms, and Asystole.Jan 14, 2003
What does PEA mean in cardiac?
Cardiology. 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.
How does PEA work?
As a result, PEA is usually noticed when a person loses consciousness and stops breathing spontaneously. This is confirmed by examining the airway for obstruction, observing the chest for respiratory movement, and feeling the pulse (usually at the carotid artery) for a period of 10 seconds.
