From: Feasibility of absolute cerebral tissue oxygen saturation during cardiopulmonary resuscitation
Cerebral tissue oxygen saturation (SctO 2 (%)) (monitored with FORE-SIGHT™ technology) and arterial blood pressure (mmHg) in an in-hospital cardiac arrest patient (patient 3). After 14 minutes of BLS by a trained caregiver, first measured SctO2 values were 48% and 52% over the left (grey line) and right (black line) fontal region, respectively. Switch of person giving CPR (arrows) resulted in increased cerebral oxygen saturations. Parallel fluctuations were observed between SctO2 and systolic blood pressure (thin black line). After cessation of CPR, SctO2 decreased to values between 30% and 35%. BLS, basic life support; CPR, cardiopulmonary resuscitation.
