On this episode, we cover two papers on the use of ultrasound hemodynamic findings in clinically evaluating blood loss: one in suspected upper GI bleeding to risk stratify patients into transfusion candidates vs not at the bedside, and the other covering an emerging use of wearable ultrasound to relate carotid Doppler findings with cardiac output.
