Remember when we learned interruptions in compressions take a long time to recover blood pressure from? And how, to avoid these, we should do continuous compressions to avoid them. And ventilations aren’t all that important. Right? Right? Well, about that. Maybe the stories of the importance of continuous compressions were greatly exaggerated. Join Dr. Jarvis as he discusses the literature that led us to this point and some evidence that has led him to reconsider how his system approaches cardiac arrest. He’ll eventually get around to discussion a recent paper by Dr. Rose Yin that analyzes arterial pressures during cardiac arrest that was a catalyst for him to make changes in his arrest protocols. Citations:1.
