While PEA is classified as a form of cardiac arrest, significant cardiac output may still be present which may be determined and best visualized by bedside ultrasound (echocardiography). Cardiopulmonary resuscitation (CPR) is the first treatment for PEA, while potential underlying causes are identified and treated.
What to do if a patient is in PEA?
A cardiac arrest patient who presents with PEA as their initial rhythm is a challenge to the resuscitation team.
- Pay attention to the ECG rhythm.
- Assess the patient’s medical history.
- Get a 12-lead ECG.
- If it’s PEA from traumatic arrest, hold off on CPR.
- Investigate point of care ultrasound.
Is PEA non shockable?
Pulseless electrical activity (PEA) is a condition where your heart stops because the electrical activity in your heart is too weak to make your heart beat. When your heart stops, you go into cardiac arrest, and you don’t have a pulse. PEA is a “nonshockable” heart rhythm, meaning a defibrillator won’t correct it.
Does PEA always turn into asystole?
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).
Rules for PEA and Asystole.
| PEA Regularity | Any rhythm including a flat line (asystole). |
|---|---|
| P Wave | Possible P wave or none detectable. |
Is the heart beating during PEA?
True PEA is a condition in which cardiac contractions are absent in the presence of coordinated electrical activity.
When do you stop CPR in peas?
A general approach is to stop CPR after 20 minutes if there is no ROSC or viable cardiac rhythm re-established, and no reversible factors present that would potentially alter outcome.
What is 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 are the 4 shockable rhythms?
The four arrest rhythms seen are asystole, pulseless electrical activity, ventricular fibrillation and pulseless ventricular tachycardia. These can be divided into non-shockable and shockable rhythms. Non- shockable rhythms include asystole and pulseless electrical activity.
Can you survive PEA?
PEA is associated with a better prognosis than asystole but worse than that of VF. The survival rates to hospital discharge are approximately 4–7%, 2% and 17–21%, respectively[1, 7–10]. Incidences for hospital discharge are estimated to be 3.6/100 000/year for VF patients and 2.2/100 000/year for all-rhythm OHCA[1].
Can you do CPR on asystole?
Asystole is treated by cardiopulmonary resuscitation (CPR) combined with an intravenous vasopressor such as epinephrine (a.k.a. adrenaline).
Can you survive asystole?
Overall the prognosis is poor, and the survival is even poorer if there is asystole after resuscitation. Data indicate that less than 2% of people with asystole survive. Recent studies do document improved outcomes, but many continue to have residual neurological deficits.
Why do you not defibrillate asystole?
The Advanced Life Support guidelines do not recommend defibrillation in asystole. They consider shocks to confer no benefit, and go further claiming that they can cause cardiac damage; something not really founder in the evidence.
What are initial steps of treating asystole PEA?
ACLS Cardiac Arrest PEA and Asystole Algorithm
- Perform the initial assessment.
- If the patient is in asystole or PEA, this is NOT a shockable rhythm.
- Continue high-quality CPR for 2 minutes (while others are attempting to establish IV or IO access)
- Give epinephrine 1 mg as soon as possible and every 3-5 minutes.
What happens during PEA?
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.
Do you give EPI for PEA?
Epinephrine should be administered in 1-mg doses intravenously/intraosseously (IV/IO) every 3-5 minutes during pulseless electrical activity (PEA) arrest.
How do you treat PEA in ACLS?
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.
Do you do CPR if someone is bleeding?
If you’re in any doubt, treat the injury as a broken bone. If the person is unconscious or is bleeding heavily, these must be dealt with first by controlling the bleeding with direct pressure and performing CPR.
Does no pulse mean no heartbeat?
A weak pulse means you have difficulty feeling a person’s pulse (heartbeat). An absent pulse means you cannot detect a pulse at all.
What is the most common cause of pulseless electrical activity?
Respiratory failure leading to hypoxia is one of the most common causes of pulseless electrical activity, responsible for about half of the PEA cases.
What are the 3 lethal heart rhythms?
You will need to be able to recognize the four lethal rhythms. Asystole, Ventricle Tachycardia (VT), Ventricle Fibrillation (VF), and Polymorphic Ventricle Tachycardia (Torsade de pointes).
What 2 rhythms will an AED shock?
The computer analyzes the heart rhythm and advises the operator whether a shock is needed. AEDs advise a shock only to ventricular fibrillation and fast ventricular tachycardia. The electric current is delivered through the victim’s chest wall through adhesive electrode pads. Why are AEDs important?
