The various parameters from multimodal monitoring, including PtiO2, were collected retrospectively in a series of 6 patients with acute subarachnoid hemorrhage. All data were recorded in a computer software and evaluated the correlations between PtiO2 and various respiratory and blood gas parameters using linear regression and multiple regression analysis. Moreover, in 2 of 6 patients, we also performed concurrently hemodynamic monitoring and analyzed the correlations between PtiO2 and some hemodynamic parameters. The results showed a variety of positive and negative correlations between PtiO2 and various parameters which were found significantly. In addition, from the multiple regression analysis using stepwise method, PtiO2 value might be predicted by 4 parameters; namely, cerebral perfusion pressure (CPP), serum bicarbonate (HCO3), oxygen saturation (O2sat) and hemoglobin (Hb).
