Cardiac arrest is a life-threatening emergency caused by the sudden loss of effective cardiac output and circulation. In this video, we review the core principles of cardiac arrest, including in-hospital cardiac arrest, out-of-hospital cardiac arrest, arrest rhythms, pathophysiology, reversible causes, resuscitation priorities, and management.
Topics covered include:
• What cardiac arrest is
• In-hospital cardiac arrest
• Out-of-hospital cardiac arrest
• IHCA versus OHCA
• Pathophysiology of cardiac arrest
• Loss of cardiac output and tissue perfusion
• Shockable rhythms
• Ventricular fibrillation and pulseless ventricular tachycardia
• Non-shockable rhythms
• Pulseless electrical activity and asystole
• Reversible causes of cardiac arrest
• Hs and Ts
• CPR and defibrillation priorities
• Airway and ventilation considerations
• Epinephrine and ACLS medications
• Post-arrest care and ROSC considerations

7:01 - 8:59 - In-Hospital Cardiac Arrest (IHCA) vs Out-Of-Hospital Cardiac Arrest (OHCA)
9:00 - 13:04 - Pathophysiology, Organ Injury and Failure, Tissue Hypoxia
13:05 - 15:56 - Rhythm Analysis, Shockable vs Non-Shockable, Vfib, Vtach, Asystole, PEA
15:57 - 19:19 - Causes, H's and T's, Cardiac and Non-Cardiac Causes
19:20 - 21:49 - Basics of Management, Chest Compressions, Early Defibrillation
21:50 - 24:07 - Prognosis, IHCA vs OHCA, Neurological Outcomes, ROSC, Survival
