The introductory video to AAA POCUS for medical students, trainees, and early learners. Start with the fundamentals. Xiphoid to umbilicus, proximal aorta to the bifurcation. Measure the diamter to be less than 3cm and you have ruled out the dreaded AAA. I want to know about the aorta in the older patient with abdominal and back pain. This is so simple, I wish more of my residents did this and told me the results on their initial presentation rather than sending them back to do it.
