Fig. 4From: Protective mechanical ventilation with optimal PEEP during RARP improves oxygenation and pulmonary indexesParameters of the phase 2 study, including a arterial partial pressure of oxygen/fraction of inspiration O2 (PaO2/FiO2), b arterial partial pressure of carbon dioxide (PaCO2), and c pulse oximetry measured oxygen saturation (SpO2). Assessments were performed before anesthesia (baseline) and at post-induction of anesthesia (T1), 20 min after each RM (T2 and T3), and 30 min after extubation (T4)Back to article page
