Today we are fortunate to welcome Sam Hsu, MD, RDMS, Assistant Professor for the University of Maryland Medical School. Dr. Hsu is the acting Emergency Department Ultrasound Director at one of the UMMC satellite centers her in Baltimore, Mercy Medical Center. He also takes on command of medical student emergency ultrasound education for the medical school. I guess you could say, he lives and breaths ED ultrasound! Today he takes us through his algorithm on how to approach ultrasonography of the lungs. I have attending many lectures on the topic and have even performed lung US research, but this lecture is the best presentation I have ever seen on the topic. You NEED to watch this lecture.
