Retrospective evaluation of cardiopulmonary arrest and resuscitation in hospitalized birds: 41 cases (2006-2019).

There was no standardized approach to avian CPR in this study, and ROSC was rare. When ROSC was achieved, birds were under general anesthesia with direct monitoring by a clinician, were ventilated, and were administered anesthetic reversals and anticholinergic or catecholamine emergency medications. These poor outcomes suggest that further research and an updated standardized approach to avian CPR, with special consideration of the physiological differences from mammals, are needed.
