And…we are back for part 3 of our coverage of some of the research from NAEMSP2020 in San Diego. If you missed parts 1 or 2, be sure to download them and take a listen. They were great! In this episode, we have two great interviews. We talk with Dr. Veer Vithalani of MedStar in Fort Worth, TX about his work using EtCO2 to detect unrecognized BVM ventilation failures. We also chat with Drs. Casey Patrick and Rob Dickson from Montgomery County Hospital District EMS in Conroe, Tx about push-dose drugs including epinephrine and nitroglycerin.
