Initial treatment of asystole/PEA is as follows: Continue CPR for 2 minutes.
Check pulse and rhythm every 2 minutes, as follows:
- If nonshockable, see Nonshockable Rhythm (above).
- If shockable, see Shockable Rhythm (above).
- Rotate chest compressors.
- Identify and treat reversible causes.
What is the first treatment for asystole?
When treating asystole, epinephrine can be given as soon as possible but its administration should not delay initiation or continuation of CPR. After the initial dose, epinephrine is given every 3-5 minutes.
What is the correct protocol for asystole?
Asystole is a non-shockable rhythm. Therefore, if asystole is noted on the cardiac monitor, no attempt at defibrillation should be made. High-quality CPR should be continued with minimal (less than five seconds) interruption. CPR should not be stopped to allow for endotracheal intubation.
Which drug is given first to a patient with pulseless electrical activity PEA?
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.
How do you treat PEA rhythm?
If PEA happens inside a hospital, the following treatments are likely:
- CPR. This is always a key part of treatment inside and outside the hospital environment.
- Epinephrine. This medication, also known as adrenaline, can help restore your heart to a normal rhythm.
- Treating the cause of PEA.
When asystole is suspected the nurse should?
If asystole is suspected, the nurse in the RPA should verify that all of the leads are connected correctly (Szabó et al., 2019). Presence of asystole should be verified in two leads (i.e., a combination of two leads—I, II, or III on a cardiac monitor.)
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.
Why do you not shock PEA?
Why not shock a PEA Arrest? In a PEA arrest, similar to Asystole, the heart doesn’t have the means to use the shock you’re sending it because the primary cause has yet to be corrected. Shocking a heart in PEA arrest is like kicking a comatose patient in the abdomen (which we do not recommend).
Do you give adrenaline in asystole?
If asystole or PEA is identified give adrenaline (epinephrine) 10 micrograms per kilogram intravenously or intraosseously. Adrenaline (epinephrine) is the first line drug for asystole.
Do you shock PEA?
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.
Do you give atropine for PEA?
Atropine is no longer recommended by the American Heart Association (AHA) for asystole and pulseless electrical activity (PEA).
Why do you not defibrillate asystole?
Asystole isn’t a shockable rhythm, and defibrillation may actually make it harder to restart the heart. Defibrillation is only an option if your heart goes from asystole to a shockable rhythm, which is possible when someone with asystole receives effective CPR.
What is the initial treatment response for a patient in either pulseless ventricular tachycardia or ventricular fibrillation?
Treatment for ventricular tachycardia may include medication, a shock to the heart (cardioversion), catheter procedures or surgery to slow the fast heart rate and reset the heart rhythm.
What drugs are used for PEA?
Pharmacologic Therapy
Resuscitative pharmacology includes epinephrine and atropine. Epinephrine should be administered in 1-mg doses intravenously/intraosseously (IV/IO) every 3-5 minutes during pulseless electrical activity (PEA) arrest.
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.
What is P wave asystole?
P waves may be present if AV block exists, but no QRS complexes are observed. Primary asystole occurs when the Purkinje fibers intrinsically fail to generate a ventricular depolarization. It is usually is preceded by a bradyarrhythmia due to complete heart block, sick sinus syndrome, or both.
Can you have a pulse with asystole?
As mentioned earlier, asystole is a lack of electrical activity in the heart so the monitor will show a flat line without measurable heart beats. The person will not have a pulse, however patients with other types of cardiac arrest also do not have a pulse.
How do you reset a flatline heart?
The only effective treatment is to deliver an electrical shock using a device called a defibrillator (to de-fibrillate the heart), which stops the chaotic rhythm of a heart in VF, giving it the chance to restart beating with a normal rhythm.
Is asystole a completely straight line?
A completely straight line indicates usually that a monitoring lead has become disconnected. During asystole the ECG usually shows slight undulation of the baseline, and may show electrical interference due to respiratory movement, or chest compression.
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.
Can you survive PEA?
PEA and then asystole may occur during this period if ventilatory support is not established in time; resuscitation can still result in a good outcome if the insult is time limited. Ventilatory support can allow the long-term outcome to become clear.
