EM Basic is back with another episode of the EM Basic Project. In today's episode Drs. Tim Peck and Colby Redfield review the chief complaint of shortness of breath with a focus on COPD. Even though we did an episode on shortness of breath a while back, it's always great to get a new perspective on this chief complaint. Today's episode also features a very special guest cameo by the name of Dr. Peter Rosen. He pretty much started EM as a speciality and you may have seen his name on a textbook or two.
