sudden cardiac arrest
Start with the big picture
Sudden cardiac arrest is marked by abrupt loss of pulse, unresponsiveness, and absence of normal breathing. Early priorities are to confirm the absence of a pulse promptly, call EMS, and begin effective CPR while minimizing interruptions. Defibrillation and subsequent management depend on whether the rhythm is shockable, such as VF or pulseless VT, or non-shockable, such as asystole or PEA. The broader response includes appropriate airway and ventilation support, capnography, and attention to reversible causes. After return of spontaneous circulation, care shifts to supporting oxygenation and circulation and managing temperature. Pharmacists contribute through crash-cart readiness, medication checks, dosing resources, and documentation.
What you'll learn
- Recognize the defining signs of sudden cardiac arrest and outline the immediate response.
- Describe CPR quality priorities, including compression technique and minimizing interruptions.
- Distinguish the initial rhythm-management approach for shockable and non-shockable rhythms.
- Explain the roles of airway support, capnography, reversible-cause assessment, and post-ROSC care.
- Identify pharmacist responsibilities in cardiac-arrest preparedness and documentation.
