Abstract in brief

• The International Cardiac Arrest Research (I-CARE) aims to create a standardized database for studying acute brain injury in cardiac arrest patients through continuous electroencephalography (EEG) across multiple centers in the US and Europe.
• Data from 1,020 comatose patients were collected, including 56,676 hours of EEG monitoring, revealing that most patients did not survive, while some achieved varying degrees of neurological recovery.
• The database highlights significant findings, like variations in EEG patterns based on neurological outcomes, and includes features like spike frequency and burst suppression, which have implications for understanding brain function after cardiac arrest.
