The newest on point of care ultrasound is discussed in the patient with vaginal bleeding in early pregnancy. The various types of spontaneous abortion including septic abortion are reviewed as well as the management of the unstable patient with massive vaginal hemorrhage.

Episode 21: Pulmonary Embolism

In this episode on Pulmonary Embolsim we have the triumphant return of Dr. Anil Chopra, the Head of the Divisions of Emergency Medicine at University of Toronto, and Dr. John Foote the CCFP(EM) residency program director at the University of Toronto.
