2. Fig 1
Schematic representation of the alveolar recruitment strategy. In pressure control ventilation, the pressure amplitude of 20 cm H2O remains constant throughout the maneuver. Respiratory rate is 12 rpm and the inspiratory:expiratory ratio is 1:1. Each pressure step is maintained for 1 minute. After recruitment pressures of 40/20 cm H2O, pressures decreased to 30/10 cm H2O. Then, the initial settings are resumed. (Paw = pulmonary artery wedge; PEEP = positive end-expiratory pressure; Pip = peak inspiratory pressure.)

3. Fig 2
Pao2 (mm Hg) in all patients during two-lung ventilation (TLV), and one-lung ventilation (OLV) before and after the alveolar recruitment strategy. Each symbol represents one single patient in every point of study. Horizontal bars represent mean values at each point. (ARS = alveolar recruitment strategy; PaO2 = arterial oxygen pressure [tension].)
