Mock Code Blue Scenario: ACLS Review for Nurses

Mock Code Blue Scenario Walkthrough

• 🩺 The episode details a mock "mega code" scenario involving a patient, Mr. Williams, presenting with supraventricular tachycardia (SVT).
• 💡 The scenario progresses through various cardiac rhythms and interventions, serving as a comprehensive review of ACLS guidelines.

SVT Management and Progression

• ⚡ Mr. Williams initially presents with SVT at a rate of 160, with a narrow QRS and no P-waves, treated first with vagal maneuvers.
• 💊 When vagal maneuvers fail, adenosine 6 mg is administered rapidly via IV push, followed by a second dose of adenosine 12 mg, both without success.
• ⚠️ As Mr. Williams becomes unstable with hypotension and symptoms like dizziness and shortness of breath, synchronized cardioversion is indicated.

Ventricular Tachycardia and Pulseless VT

• 🚨 The scenario shifts to pulseless ventricular tachycardia (VTAC), initiating immediate CPR and defibrillation.
• 💉 Epinephrine 1 mg is administered, and consideration is given to securing an advanced airway.
• 🔄 CPR is resumed immediately after shocks, with compressor switches every two minutes to maintain effectiveness.

Post-ROSC and Bradycardia Management

• ❤️ Following resuscitation attempts, Mr. Williams achieves return of spontaneous circulation (ROSC), but presents with a third-degree heart block and bradycardia.
• ⚡ External pacing is initiated, and mechanical capture is confirmed by correlating pacing spikes with a palpable pulse.
• 💊 Sedation with midazolam (Versed) is considered for patient comfort during transcutaneous pacing.

Final Patient Disposition and Key Takeaways

• 🏥 Mr. Williams is transferred to the cardiac ICU for further monitoring and potential permanent pacemaker placement.
• 📚 The episode covers management of SVT, VTAC, pulseless VT, and bradycardia, emphasizing the importance of ACLS algorithms and critical thinking in code situations.
• 🧠 Reversible causes of cardiac arrest, the "H's and T's," are highlighted as crucial considerations during resuscitation efforts.
