The purpose of this free "course" is for it to continually improved. I have contributed absolutely no content, but simply arranged free resources in a logical manner. It takes 10 minutes to set up the course for yourself. And each lesson ranges from 1 to 2 hours.
Lesson 1 through 4 are cardiac, aorta, ruq, and renal/ureter/bladder. Lesson 5 is a review of what you've learned. The next lesson will be FAST, which you will be able to perform well now that you have knowledge of all 4 views.
I can't possibly know what all the free resources out there are. So please comment and contribute and help others teach themselves how to be better at ultrasound. I'm particularly interested in ultrasound videos that clinically correlate so that we can improve our practice and knowledge base of EM, not just ultrasound.
I look forward to this project evolving and thank you in advance for all of your help. A special thanks to Tarina Kang, ultrasound director at Beth Israel - Deaconess Medical Center/Harvard Affiliated Emergency Medicine Residency for supporting this vision.
