Cardiac Arrest due to stroke (less likely) Required Actions: - Dispatch of ground EMS with ALS capabilities immediately - Immediate instructions to caller for CPR - Early notification to hospital for cardiac arrest team activation - Preparation for potential defibrillation and advanced airway management
