Cardiac Arrest Recovery EEG Study

The purpose of the study is to collect EEG's as close to the cardiac arrest as possible using a standard hospital EEG machine and an investigational EEG device to help determine the neurological status of the cardiac arrest patient and to help decide on possible treatment and chance of recovery. The investigational EEG machine will be simple to operate as well as easy to interpret for the clinician and the nurses. It is not to replace the electrophysiologist interpretation but to determine ealy on if further evaluation and treatment can help the patient.
