Serial changes in rSO2 values during LDB-CPR in a) all patients, b) patients with ROSC, and c) patients without ROSC. Data are expressed as group means ± standard error of the mean. Comparisons of variables between groups were analyzed by analysis of variance adjusted for the pre-rSO2 values as a covariate, and p values for main treatment effect between groups indicated. *Denotes statistically significant (p < 0.05) difference between groups. rSO2: regional cerebral oxygen saturation; LDB-CPR: load-distributing-band cardiopulmonary resuscitation; ROSC: return of spontaneous circulation.
