Table 1. Blood Gas Results and Potential Confounding Factors as a Function of Target End-Tidal Pco²

None of the values below the middle space differed significantly between CO²concentrations. Data presented as mean ± SD.

MAP = mean arterial pressure; RR = respiratory rate; Spo²= oxygen saturation as determined by pulse oximeter; Pao²and Paco²= arterial oxygen and carbon dioxide partial pressures.
