Table 2 Cerebral Performance Categories/CPC scale
From: Automated external cardioversion defibrillation monitoring in cardiac arrest: a randomized trial
CPC 1: Good cerebral performance – conscious, alert, able to work, might have mild neurologic or psychological deficit. |
|---|
CPC 2: Moderate cerebral disability – conscious, sufficient cerebral function for independent activities of daily life. Able to work in sheltered environment. |
CPC 3: Severe cerebral disability – conscious, dependent on others for daily support because of impaired brain function. Ranges from ambulatory state to severe dementia or paralysis. |
CPC 4: Coma or vegetative state – any degree of coma without the presence of all brain death criteria. Unawareness, even if appears awake (vegetative state) without interaction with environment; may have spontaneous eye opening and sleep/awake cycles. Cerebral unresponsiveness. |
CPC 5: Brain death – apnea, areflexia, EEG silence, etc. |
