In a recent issue of Critical Care Medicine, Parnia et al (1) have published an intriguing large study documenting higher cerebral oxygenation during cardiopulmonary resuscitation (CPR) revealing that cerebral performance category (CPC) 1-2 survivors had higher regional cerebral oxygenation (rSO2) values during CPR. The mean rSO2 values were 51.8 +- 11.2 versus 40.9 +- 12.3 in return of spontaneous circulation (ROSC) and no-ROSC group, respectively.
In the ROSC group, the differences in neurologic outcome CPC 1-2 versus CPC 3-5 was even more pronounced: 56 +- 10 versus 44 +- 14. This observation could lead to the feeling that low rSO2 values are associated with poor outcome, as was shown also in some smaller studies (2, 3).
