From: Feasibility of absolute cerebral tissue oxygen saturation during cardiopulmonary resuscitation
Cerebral tissue oxygen saturation (SctO 2 (%)) (monitored with EQUANOX Advance™ technology) during out-of-hospital cardiac arrest (patient 7). The starting SctO2 value (after 20 minutes of BLS) was 3%, but rose quickly to 21%. The highest measured value during CPR was 38%. A decrease in SctO2 was observed during rhythm assessment (every 2 minutes). CPR was stopped 50 minutes after arrival of the medical emergency team, without obtaining ROSC. After termination of CPR, SctO2 decreased rapidly. BLS, basic life support; CPR, cardiopulmonary resuscitation; ROSC, return of spontaneous circulation.
