Well, this show will let you see emergencies unfold through the eyes of a Rapid Response Nurse. With real life stories from the frontlines of nursing, host Sarah Lorenzini MSN, RN, CCRN, CEN, a Rapid Response Nurse and educator, shares her experiences at rapid response events and breaks down the pathophysiology, pharmacology, and the important role the nurse plays during emergencies. If you want to sharpen your assessment skills and learn how to think like a Rapid Response Nurse, then Sarah is here to share stories, tips, tricks, and mindsets that will prepare you to approach any emergency. Every episode is packed full of exactly what you need to know to handle whatever crisis that could arise on your shift. It’s one thing to get the right answer on the test, but knowing how to detect when YOUR patient is declining and what to do when YOUR patient is crashing is what will make or break your day… and might just save your patient’s life.","last_synced_at":"2026-06-19T22:19:22.292365+00:00","page_url":"https://stenobird.com/podcast/rapid-response-rn-1369016"},"episode":{"title":"164: Electrical Storm Part 1:The Pathophysiology of Ventricular Storm and the Science of Defibrillation","slug":"164-electrical-storm-part-1-the-pathophysiology-of-ventricular-storm-and-the-science-of-defibrillation","published_at":"2026-06-19T12:00:00+00:00","page_url":"https://stenobird.com/podcast/rapid-response-rn-1369016/164-electrical-storm-part-1-the-pathophysiology-of-ventricular-storm-and-the-science-of-defibrillation","show_page_url":"https://stenobird.com/podcast/rapid-response-rn-1369016","url":"https://healthpodcastnetwork.com/show/rapid-response-rn/","audio_url":"https://pscrb.fm/rss/p/episodes.captivate.fm/episode/83f78557-8529-4a1b-b021-74785686ba45.mp3","summary":"Sometimes V-fib doesn't respond to the shock at all. Sometimes it converts and comes right back. Those are two completely different problems. In this episode, Sarah breaks down the science behind why defibrillation fails, how to recognize the difference between refractory and recurrent V-fib, and respond when shocks aren't working. You'll learn how to start approaching the electrical storm at the bedside — that means understanding transthoracic impedance, optimizing your pad placement, and knowing when to reach for double sequential defibrillation. Topics discussed in this episode: Refractory vs. recurrent V-fib The physiology of ventricular fibrillation and re-entry tachycardias Misconceptions about defibrillation Transthoracic impedance and how to reduce it Anterior-lateral vs. anterior-posterior pad placement Double sequential defibrillation: evidence and objections Key findings from the DOSE VF trial American Heart Association.
