About this calculator

Outcome definition (CPC).
The Cerebral Performance Category (CPC) scale is a commonly used measure of neurologic outcome following cardiac arrest. CPC ranges from 1 to 5, where CPC 1 indicates good cerebral performance, CPC 2 moderate disability but independent function, CPC 3 severe disability, CPC 4 vegetative state, and CPC 5 death. In this calculator, a favorable neurologic outcome is defined as survival to hospital discharge with a CPC of 1-2.

Model development.
This calculator was developed and validated using data from adult patients supported with extracorporeal cardiopulmonary resuscitation (ECPR). These data were derived from the Extracorporeal Life Support Organization (ELSO) patient registry, which maintains a comprehensive registry of patients undergoing extracorporeal life support at centers worldwide.

Intended use.
This tool is intended to support clinical discussion, risk stratification, and shared decision-making. It is not intended to be used in isolation to determine candidacy for ECPR or decisions about life-sustaining therapy.
