Two factors to cardiac arrest survivability that have been clearly shown to make the biggest difference is continuous, high-quality CPR and early defibrillation. The most common dysrhythmia present during the first few minutes of cardiac arrest is ventricular fibrillation. The chance of successful defibrillation decreases every minute that passes.  How our chance of successfully defibrillating a patient into a perfusing rhythm significantly changes when good CPR is delivered vs when it isn't. Why bystander CPR is important for out-of-hospital cardiac arrest (OHCA) outcomes.  The role of the CPR coach. Five tips to aid us in limiting CPR interruptions to less than 10 seconds so we can maintain a chest compression fraction (CCF) of at least 80%.Connect with me:Website:  https://passacls.com@PassACLS on X (formally known as Twitter)@Pass-ACLS-Podcast on LinkedInGive back - buy Paul a bubble tea hereGood luck with your ACLS class!
