It is not only the "fresh"/new providers who can make a mistake, even seasoned individuals, who for many reasons can overlook the obvious. The way you handled the “correction” is to be applauded. Unfortunately many ALS providers are afflicted with the “I am GOD” syndrome and “never” make mistakes. The same method you used to “correct” an oversight would be well employed by many ALS providers who treat BLS personnel like idiots. A gentle reminder or whisper can do a lot to foster relationships between varying levels of EMS providers. Although, I must admit, I have gotten somewhat verbal when I have to constantly remind the BLS provider to continue with ventilations instead of watching me. Pete
