From: Alveolar instability caused by mechanical ventilation initially damages the nondependent normal lung
Schematic demonstrating in vivo videomicroscopy procedure for the nondependent and dependent lung. The right lung was filmed in all groups (that is, dependent and nondependent lung and high and low positive end-expiratory pressure). (a) To film the nondependent lung, the rat was placed in the left lateral decubitus position and the microscope was lowered from the top. (b) To film the dependent lung, the rat was in the lateral decubitus position with an open chest and the microscope was elevated from the bottom.
