Ventilatory, gas exchange and hemodynamic parameters in healthy baseline and injured lungs at different PEEP.

N = 9. Values are means ± standard deviations. Pendinsp: end-inspiratory airway pressure; PEEP: positive end-expiratory pressure; RR: respiratory rate; VT: tidal volume; Crs: respiratory system compliance; Flow: airway flow; FIO2: fraction of inspired oxygen; PaO2: arterial partial pressure of oxygen; PaCO2: arterial partial pressure of carbon dioxyde; SpO2: peripheral saturation; HR: heart rate; SAP, systolic arterial pressure; DAP, diastolic arterial pressure; MAP, mean arterial pressure; MPAP, mean pulmonary arterial pressure; CVP, central venous pressure.
