Objective: to compare the effect of alveolar recruitment manouver through stepwise increase and decrease in airway pressure or sustained 30 secondes 30 cmH2O continuous positive airway pressure on cardiac stroke volume estimated by oesophageal doppler in preload independent anesthetized patients scheduled for surgery.
Following anesthesia and preload optimisation guided by cardiac stroke volume, patients will be randomised to one alveolr recruitment manoeuver : * stepwise increase and decrease in positive airway pressure * sustained 30 secondes 30 cmH2O continuous positive airway pressure The primary objective is the change in cardiac stroke volume.
