Reassessment Campaign on Veterinary Resuscitation (RECOVER) Initiative Small Animal CPR Registry Report 2025.

CPR survival to discharge is rare (3-4%); euthanasia decisions significantly impact outcome reporting.

The RECOVER CPR registry represents a comprehensive international multi-institutional database tracking cardiopulmonary arrest and resuscitation outcomes in small animals. This 2025 report analyzes 1,665 CPR events from 1,207 dogs and 458 cats collected between February 2016 and January 2025 across 22 hospitals in North America, Europe, Australia, and Asia. Return of spontaneous circulation (ROSC) was achieved in 28% of animals, with sustained ROSC in 16% of dogs and 17% of cats. Discharge survival rates remained low at 4% for dogs and 3% for cats. Notably, euthanasia was the primary cause of death in approximately 70% of animals achieving sustained ROSC but not surviving to discharge. These findings underscore that CPR outcomes remain poor and highly variable depending on setting and modifiable factors. The registry's growth demonstrates its value for collaborative research in understanding CPA epidemiology and identifying interventions that may improve survival rates in veterinary emergency medicine.
