What is the standard medication to use for asystole?
For asystole, the standard medication to use is epinephrine. While treating asystole, epinephrine should be administered as soon as possible without delaying the start or continuation of CPR. Following the initial dose, epinephrine is given every 3-5 minutes as needed.
When should epinephrine be given to a patient with 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. Rhythm checks should be performed after 2 minutes (5 cycles) of CPR.
What is the prognosis of asystole?
For most patients, true asystole is the result of a prolonged illness or cardiac arrest, and prognosis is very poor. The few patients that have a positive outcome following a diagnosis of cardiac arrest with asystole will usually result from the identification and correction of an underlying cause of the asystole.
Is there a way to reverse asystole?
When a reversible underlying cause is found, that cause should be treated directly to reverse asystole. Some theoretically reversible causes of asystole include: Because asystole is not a shockable rhythm, defibrillation is not an effective asystole treatment.
How is asystole treated?
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. Rhythm checks should be performed after 2 minutes (5 cycles) of CPR.
Which medication should be administered during the resuscitation of a patient with ventricular fibrillation?
The guidelines recommend administration of amiodarone for sustained ventricular fibrillation (Vf) and ventricular tachycardia (VT) refractory to CPR, defibrillation, and vasopressor in out-of-hospital cardiac arrest. Lidocaine is recommended as an alternative to amiodarone.
What dysrhythmia is defibrillation primarily indicated as the treatment?
Ventricular tachycardia (v-tach) typically responds well to defibrillation. This rhythm usually appears on the monitor as a wide, regular, and very rapid rhythm. Ventricular tachycardia is a poorly perfusing rhythm; patients may present with or without a pulse.
What is asystole?
Asystole, colloquially referred to as flatline, represents the cessation of electrical and mechanical activity of the heart. Asystole typically occurs as a deterioration of the initial non-perfusing ventricular rhythms: ventricular fibrillation (V-fib) or pulseless ventricular tachycardia (V-tach).
What drugs are used in resuscitation?

Which intervention is most appropriate for asystole?
Asystole is treated by cardiopulmonary resuscitation (CPR) combined with an intravenous vasopressor such as epinephrine (a.k.a. adrenaline).
Which drug is considered first line treatment for asystole or PEA?
The only two drugs recommended or acceptable by the American Heart Association (AHA) for adults in asystole are epinephrine and vasopressin. Atropine is no longer recommended for young children and infants since 2005, and for adults since 2010 for pulseless electrical activity (PEA) and asystole.
When does adenosine stop?
Patients with irregular heart rates, especially atrial fibrillation, patients with PSVT mimics such as atrial flutter with 2:1 conduction or sinus tachycardia in a dehydrated or stressed patient should never receive adenosine. Adenosine should never be used in wide irregular tachycardias.
What is the first line treatment for ventricular fibrillation?
If the patient remains in ventricular fibrillation, pharmacological treatment should begin. Epinephrine is the first drug given and may be repeated every 3 to 5 minutes. If epinephrine is not effective, the next medication in the algorithm is amiodarone 300 mg.
Will AED shock asystole?
Children or adults who develop cardiac arrest caused by a slowing of the heart rate (bradycardia) or cardiac standstill (asystole) cannot be treated with an AED. These rhythms do not respond to electric shocks, so the AED will not allow a shock to be activated and standard CPR measures should be performed.
What happens when a patient is in asystole?
Asystole is a type of cardiac arrest, which is when your heart stops beating entirely. This usually makes you pass out. It's also likely that you'll stop breathing or that you'll only have gasping breaths. Without immediate CPR or medical care, this condition is deadly within minutes.
Why is cardiac asystole?
Asystole is caused by a glitch in your heart's electrical system. You can get a ventricular arrhythmia when the signals are off. That's when your lower chambers don't beat the right way. So your heart can't pump blood to the rest of your body.
What is the name of the medication that produces vasoconstriction and a rise in blood pressure?
Vasopressors. A vasopressor is a medication that produces vasoconstriction and a rise in blood pressure. The vasopressor that is used for the treatment within the right branch of the Cardiac Arrest Algorithm is epinephrine. Epinephrine is primarily used for its vasoconstrictive effects.
What is the definition of asystole?
Asystole is defined as a cardiac arrest rhythm in which there is no discernible electrical activity on the ECG monitor. Consequently, it is sometimes referred to as a “flat line.” Confirmation that a “flat line” is truly asystole is an important step in the ACLS protocol.
Why is epinephrine used in CPR?
Epinephrine is primarily used for its vasoconstrictive effects. Vasoconstriction is important during CPR because it will help increase blood flow to the brain and heart. When treating asystole, epinephrine can be given as soon as possible but its administration should not delay initiation or continuation of CPR.
Why should ACLS be reviewed?
The H’s and T’s of ACLS should be reviewed to identify any underlying cause that could have precipitated the asystole. Some of the most common reasons to stop or withhold resuscitative efforts are: Asystole is treated using the right branch of the Cardiac Arrest Algorithm.
Why is my VF line flat?
Fine VF can appear to be asystole, and a “flat line” on a monitor can be due to operator error or equipment failure.
How long should a rhythm check be performed?
Rhythm checks should be performed after 2 minutes (5 cycles) of CPR. Limit rhythm checks to less than 10 seconds to minimize interruptions in CPR. Pulse checks should be performed when a rhythm check reveals a change in the rhythm to a rhythm that is organized and could be generating a pulse.
Is asystole a good outcome?
Asystole for many patients is the result of a prolonged illness or cardiac arrest, and prognosis is very poor. Few patients will likely have a positive outcome and successful treatment of cardiac arrest with asystole will usually involve the identification and correction of an underlying cause of the asystole.
How often should you do a rhythm check for CPR?
Following the initial dose, epinephrine is given every 3-5 minutes as needed. During CPR, a rhythm check should be done every 2 minutes (5 cycles). These rhythm checks should be kept to less than 10 seconds, in order to prevent meaningful interruptions in CPR.
What is an asystole?
Asystole, otherwise known as a flatline, is a state of cardiac standstill in which all electrical activity has ceased.
What to do if your rhythm is incorrect?
If you believe the rhythm may be incorrect, ensure patches have good contact with the individual, leads are connected, the gain is set appropriately, and the power is on. If all equipment appears to be functioning normally, and you still see a rhythm that appears to be asystole, quick action is imperative.
What is the best medicine for asystole?
For asystole, the standard medication to use is epinephrine.
Is asystole a flatline?
Identifying Asystole. Confirmation that the rhythm is indeed a flatline, and not a false positive, is an important part of the asystole treatment algorithm. For most patients, true asystole is the result of a prolonged illness or cardiac arrest, and prognosis is very poor.
Is vasopressin a good substitute for epinephrine?
Previous versions of the AHA guidelines have suggested that higher doses of epinephrine (greater than the standard 1mg dose), or an alternative vasopressor, called vasopressin, could be more effective alternatives to the standard dose of epinephrine.
Is defibrillation effective for asystole?
Because asystole is not a shockable rhythm, defibrillation is not an effective asystole treatment. Researchers estimate that less than two percent of people who suffer asystole outside of the hospital will survive - even with trained emergency intervention.
