Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Recruitment maneuver(RM) - before and after. The RM is a stepwise increase in positive end exiratory pressure (PEEP) level from baseline to 40cm H20, with 2 minutes at each PEEP level and then reduced slowly to optimal PEEP (as determined by the SaO2)The RM will last for 10 minutes with no control. Measurement will be made before and after the one intervention (RM) in all subjects.
