MCHD's POCUS program has definitely involved both forward progress and lessons learned. In this episode, we'll discuss some of the reasons POCUS can be a game changer in the prehospital setting. However, unintended consequences do exist. We've begun to make the move to utilizing carotid ultrasound in OHCA, and we'll tell you exactly why. REFERENCES 1.
