Table 2. Ventilatory Parameters in the Two Groups after Randomization

Values are mean ± SD.

*P < 0.001.

PEEP = positive end-expiratory pressure; Fio²= oxygen inspiratory fraction; P^plat= end-inspiratory plateau pressure; V^T= tidal volume; Pao²= arterial oxygen tension; and Paco²= arterial carbon dioxide tension.
