Have you ever had a patient's aortic intima and media peel off each other like the plastic casing from a cheap laptop and wish had more tools than just shipping them off to the CT scanner? Well, the D-dimer and the suprasternal aortic notch views may be a solution to your problems!

This week, we are embolizing information from my microphone straight into your ears, as I have a systematic review covering the accuracy of DVTs performed by EM providers and a trial looking at how well a new diagnostic measure called the RV bubble time does in looking for RV dysfunction.

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.
