Definition & Pathophysiology
- Cardiopulmonary arrest (CPA) occurs when there is cessation of cardiac function and there are no spontaneous respirations.
- CPA can cause global hypoxemia, multiple organ failure, and, eventually, death.1
- Cardiopulmonary resuscitation (CPR) provides ventilatory and circulatory support to patients that undergo CPA.
- The goal is to establish oxygen delivery—most importantly, to the cerebrum and myocardium—without causing further organ injury.1
- Return of spontaneous circulation (ROSC) occurs when there is a sustained perfusing rhythm, significant breaths (more than an agonal breath), and more than a brief pulse.2
- Published in 2012, the Reassessment Campaign on Veterinary Resuscitation (RECOVER) guidelines are the first evidence-based, consensus-based guidelines for veterinary CPR.3
