Fluid Responsiveness Predicted by a Stepwise PEEP Elevation Recruitment Maneuver in Mechanically Ventilated Patients

Lung recruitment maneuver is used to reopen or prevent collapsed lung under mechanical ventilation so as to decrease respiratory complications. LRM induces a transient increase in intra-thoracic pressure and decreases in venous return, leading to a decrease in left ventricular end-diastolic area and stroke volume.
