Primary Objective:~To compare the proportion of patients developing target-obscuring atelectasis when using a lateral decubitus strategy (LADS) vs using a ventilatory strategy to prevent atelectasis (VESPA) during robotic bronchoscopy for posteriorly-located peripheral lung lesions.~Secondary Objectives:~To compare the proportion of patients with atelectasis in the target lobe in VESPA vs. LADS during robotic bronchoscopy.~To compare the proportion of patients with atelectasis obscuring 100%, 50% or more, and less than 50% of the target during robotic bronchoscopy using LADS vs. VESPA.~To compare the proportion of patients in whom a biopsy sample was not taken due to atelectasis using LADS vs. VESPA.~To compare the diagnostic yield using LADS vs. VESPA.~To compare the proportion of tool in lesion (TIL) using LADS vs. VESPA.~To compare the diagnostic accuracy (sensitivity and specificity) for malignancy using LADS vs. VESPA.~To compare the proportion of LADS-induced vs. VESPA-induced complications.~To compare the proportion of bronchoscopy-induced complications in LADS vs. VESPA.
To learn if LADS is better than VESPA at preventing atelectasis during a robotic bronchoscopy.
