Within the group of people presenting with cardiac arrest, the specific cardiac rhythm can significantly impact survival rates. Compared to people presenting with a non-shockable rhythm (such as asystole or PEA), people with a shockable rhythm (such as VF or pulseless ventricular tachycardia) have improved survival rates, ranging between 21 and ...
Pulseless electrical activity (PEA) is a form of 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 20% of out-of-hospital cardiac arrests [1] and about 50% of in-hospital cardiac arrests.
Even in those cases where an individual suffers a cardiac arrest with asystole and it is converted to a less severe shockable rhythm (ventricular fibrillation, or ventricular tachycardia), this does not necessarily improve the person's chances of survival to discharge from the hospital, though if the case was witnessed by a civilian, or better ...
The two "shockable" rhythms are ventricular fibrillation and pulseless ventricular tachycardia, while the two "non-shockable" rhythms are asystole and pulseless electrical activity. [65] Moreover, in the post-resuscitation patient, a 12-lead EKG can help identify some causes of cardiac arrest, such as STEMI which may require specific treatments.
Although a shockable rhythm increases chances for return of spontaneous circulation, a cardiac arrest can present with pulseless electrical activity or asystole, which are non-shockable cardiac rhythms. [6]
When an individual goes into cardiac arrest providers will start CPR immediately and then try to determine whether the rhythm is shockable. While defibrillation is often portrayed as a common treatment option in popular media, since asystole is an unshockable rhythm defibrillation is not a recommended course of treatment. Successful ...
Shockable rhythms are rhythms that can improve with a shock and thus, should receive a shock. Unshockable rhythms are rhythms that won't improve with a shock and thus, should NOT receive a shock. The monitor/defibrillator will either tell the providers if the rhythm is shockable (automated external defibrillators (AED)) or the providers will be ...
Termination of shockable rhythms. Note: not all cardiac arrest rhythms can be treated with defibrillation. Airway Management Endotracheal intubation, supraglottic airway placement, Cricothyrotomy, waveform capnography, tracheal suctioning, naso- or oropharygeal airway placement Cleat and protect the airway to allow for adequate ventilation.
