- CPR and Defibrillation: Immediate and effective chest compressions combined with timely defibrillation for shockable rhythms (e.g., ventricular fibrillation). - Airway Management: Ensuring an open airway using techniques such as the head-tilt-chin-lift, oropharyngeal airway (OPA), and advanced methods like endotracheal intubation. - Medication Administration: Timely administration of drugs such as epinephrine, amiodarone, and lidocaine based on specific algorithms. - ECG Interpretation: Identifying and managing arrhythmias such as asystole, pulseless electrical activity (PEA), and various forms of tachycardia.
