A focused cardiac ultrasound is commonly used in the evaluation of patients with possible pulmonary embolism (PE). Based on the literature to date, we know that this can be helpful for ruling in signs of right heart strain. On the other hand, so far, this focused exam has not been that helpful in ruling out PE. These authors try to fix that by optimizing the sensitivity of the exam in a population with abnormal vital signs.

It is an age-old question - short or long axis? Using ultrasound guidance for internal jugular vein cannulation is now fairly standard. There are a lot of opinions regarding if it is best to visualize the target in short axis (cross section) or long axis (parallel to the vein). There are certainly benefits to both. This episode features a prospective randomized trial that attempts to put an end to this debate.

Acute aortic syndromes such as aortic dissection, aortic aneurysm, penetrating ulcer are tricky. No one wants to miss these deadly diseases, but we also don't want to test everyone who has the slightest sign of this wily diagnosis. Point of care ultrasound can detect signs of aortic pathologies, but there haven't been any good studies to determine if this is accurate or safe....until now. https://www.ultrasoundgel.org/82 https://www.ncbi.nlm.nih.gov/pubmed/31226214
