ACLS Megacode Scenario 4 | ACLS Certification Association

Summary

This video presents an ACLS Megacode scenario focusing on a 52-year-old woman with a history of hypertension and type two diabetes who presents with chest pain. The video guides viewers through the identification of rhythms and appropriate interventions during a cardiac arrest event, including CPR, defibrillation, and medication administration.

Highlights

Return of Spontaneous Circulation (ROSC)00:09:18

The patient experiences a return of spontaneous circulation (ROSC) with a blood pressure of 90/60, but without spontaneous breathing, requiring ventilation.

Patient Presentation and Initial Assessment00:00:09

A 52-year-old woman with hypertension and type 2 diabetes presents to the ER with chest pain, jaw radiation, and shortness of breath. Initial assessment reveals clammy skin, regular heart rate, clear lungs, and labored breathing. The patient is anxious and uncomfortable.

Rhythm Identification: NSR with PVCs00:00:50

The initial rhythm is identified as Normal Sinus Rhythm (NSR) with Premature Ventricular Contractions (PVCs), characterized by early, wide, bizarre QRS complexes and no discernible P waves.

Immediate Intervention: Obtain 12-Lead EKG00:01:27

The immediate intervention is to obtain a 12-lead EKG to determine if there is underlying ischemia.

Patient Deterioration and Cardiac Arrest00:01:58

While starting an IV, the patient vomits, loses consciousness, and the monitor reveals a new rhythm indicative of cardiac arrest.

Intervention for Cardiac Arrest: Begin CPR00:02:31

Upon recognizing cardiac arrest, the immediate action is to begin high-quality CPR. If the rhythm is shockable, prepare for defibrillation, but do not delay CPR.

Post-Defibrillation: Continue CPR00:02:55

After defibrillation, the next crucial step is to consistently resume high-quality CPR without delay.

Persistent V-fib: Next Intervention is Defibrillation00:03:33

If the monitor continues to show V-fib after CPR, the next appropriate intervention is to defibrillate again, as V-fib is a shockable rhythm.

Medication Consideration: Epinephrine00:04:22

If a shockable rhythm persists after high-quality CPR and two defibrillations, the team should administer epinephrine one milligram IV.

Epinephrine Dosing Frequency00:05:09

Epinephrine can be repeated every three to five minutes, with no specific dosing limit.

Post-Epinephrine Administration: Continue CPR00:05:45

After administering epinephrine, high-quality CPR is essential to circulate the medication throughout the patient's system.

New Rhythm: Pulseless Ventricular Tachycardia00:06:20

After epinephrine and five cycles of CPR, the patient remains pulseless, but the rhythm changes to pulseless ventricular tachycardia, which is another shockable rhythm.

Intervention for Pulseless VT: Defibrillate and CPR00:06:54

Recognizing pulseless ventricular tachycardia, the next intervention is to defibrillate and then immediately begin high-quality CPR.

Asystole: Resume High-Quality CPR00:08:30

If after repeating amiodarone and completing five cycles of CPR, the rhythm is asystole, which is not shockable, the team must resume high-quality CPR.
