Abstract 16363: The Association Between Cerebral Oxygenation and Brain Waves Measured by Cerebral Oximetry and Electroencephalography (EEG) During Cardiopulmonary Resuscitation (CPR): A Feasibility Study

Background: Cerebral ischemia following cardiac arrest (CA) is associated with significant morbidity and mortality. A major hurdle to improving CA outcomes has been the lack of a real-time detection system capable of identifying cerebral ischemia/oxygenation as well as brain function during CPR as markers of global ischemia. In particular no studies have examined the feasibility of real-time EEG and cerebral oximetry monitoring during CPR to evaluate for these parameters. Methods: This was a single center study using a convenience sample of CA patients enrolled between 03/2014 and 03/2015. Inclusion criteria: In/out of hospital CA, age ≥ 18 years. Portable EEG (Masimo) and cerebral oximetry (Nonin) were used during CPR cases lasting u003e10 minutes. Raw EEG data were captured as consecutive images (1/second) during each pause in CPR (10 seconds), while oximetry was captured continuously. Results: 16 patients were recruited; mean age = 70±13 years; 11 males and 5 females. All subjects exhibited interpretable E...
