To investigate the use of two-site regional oxygen saturations (rSO2) and end tidal carbon dioxide (EtCO2) to assess the effectiveness of resuscitation and return of spontaneous circulation (ROSC). Eight mechanically ventilated juvenile swine underwent 28 ventricular fibrillatory arrests with open cardiac massage. Cardiac massage was administered to achieve target pulmonary blood flow (PBF) as a percentage of pre-cardiac arrest baseline. Non-invasive data, including, EtCO2, cerebral rSO2 (C-rSO2) and renal rSO2 (R-rSO2) were collected continuously. Our data demonstrate the ability to measure both rSO2 and EtCO2 during CPR and after ROSC. During resuscitation EtCO2 had a strong correlation with goal CO with r = 0.83 (p < 0.001) 95% CI [0.67–0.92]. Both C-rSO2 and R-rSO2 had moderate and statistically significant correlation with CO with r = 0.52 (p = 0.003) 95% CI (0.19–0.74) and 0.50 (p = 0.004) 95% CI [0.16–0.73]. The AUCs for sudden increase of EtCO2, C-rSO2, and R-rSO2 at ROSC were 0.86 [95% CI, 0.77–0.94], 0.87 [95% CI, 0.8–0.94], and 0.98 [95% CI, 0.96–1.00] respectively. Measurement of continuous EtCO2 and rSO2 may be used during CPR to ensure effective chest compressions. Moreover, both rSO2 and EtCO2 may be used to detect ROSC in a swine pediatric ventricular fibrillatory arrest model.
