Dr. Alexa Bersenas, DVM, MSc, Dip ACVECC

Dr. Alexa Bersenas graduated from the Ontario Veterinary College and practiced small animal medicine in Toronto for 2 yearsAlexaBersenas.jpg before returning to academia. Dr. Bersenas has been a faculty member at OVC since 2004, and currently acts as Chief of the Emergency and Critical Care Service. Dr. Bersenas has an interest in respiratory and renal failure, as well as analgesia and the provision of exceptional nursing care. In addition to patient care, Dr. Bersenas enjoys student (undergraduate and graduate) teaching, and active participation in Continuing Education; she is the recent recipient of the OVC Year í68 Award for Teaching Excellence.

Dr. Bersenasí research has focused on respiratory failure and the use of mechanical ventilation to temporarily support respiratory function in dogs and cats. Investigations include: optimal sedation plans to support ventilation while considering recovery and cost; novel forms of ventilation for potential wider clinical utility, and optimizing ventilation particularly in cats. Her own research investigated gastric acid production in dogs and the use of common gastric acid suppressants used in small animal medicine in order to better identify those patients who might benefit from this wide spread therapy. Other areas of interest include feline medicine, sepsis, acute kidney injury, and transfusion medicine.
