Prior studies have supported the use of cerebral oximetry as a predictor of survival and neurologic outcomes in patients undergoing cardiopulmonary resuscitation (CPR). In the current observational study, researchers assessed the use of real-time noninvasive cerebral oximetry during CPR in a convenience sample of 34 adults with in-hospital cardiac arrest at a single hospital during a 1-year period.
At the physician's discretion, 22 patients received manual chest compressions and 12 received automated mechanical chest compressions. Mechanical chest compression was associated with higher regional cerebral oxygen saturation (53% vs. 24%). Patients with return of spontaneous circulation (ROSC) had higher regional oxygen saturation than those wit…
