Crisis - Cardiorespiratory Emergencies

Professor Soren Boysen obtained his DVM from the University of Saskatchewan (Canada), completed a small animal internship at the Atlantic Veterinary College (Canada), and a residency at Tufts University (United States), becoming a diplomate of the American College of Veterinary Emergency and Critical Care in 2003. He is the former Chief of Small Animal Emergency and Critical Care at the University of Montreal, and currently a Full Professor of veterinary emergency and critical care at the University of Calgary. Extensively published, and a recipient of numerous teaching and research excellence awards, he has become an internationally recognized speaker. Although he loves all things ECC, he is considered a pioneer of veterinary point of care ultrasound (VPOCUS), having developed the small animal Focused Assessment of Sonography for Trauma (FAST) exam with his colleagues at Tufts. With many great colleagues from around the world he continues to actively research and develop veterinary point of care ultrasound (VPOCUS) training techniques, education programs, and workshops for non-specialist practitioners. Along with point of care ultrasound, his research interests include hemorrhage, coagulation, and perfusion.
