Brief Summary
This trial studies how well radial-probe endobronchial ultrasound works in detecting the complete or partial collapse of the lung in patients undergoing peripheral bronchoscopy. Diagnostic procedures, such as radial-probe endobronchial ultrasound and bronchoscopy, use a thin, tube-like instrument inserted through the nose or mouth to view and take pictures of the inside of the trachea, air passages, and lungs.

Outcome Measures
Primary Outcomes (2)
New atelectasis for each segment
Presence or absence of atelectasis within each of the aforementioned 8 segments will be determined using radial-probe endobronchial ultrasound (RP-EBUS) in comparison with the most recent computed tomography (CT) performed \< 4 weeks prior to the bronchoscopy. A segment will be identified as having a new atelectasis if there is an indication of solid- or semisolid-appearing lesion by RP-EBUS without a corresponding indication of solid tumor or atelectasis on the preoperative CT. Descriptive statistics (frequencies, proportions, means, standard deviations, and ranges) will be provided for patient characteristics. The proportion of patients identified as developing intraprocedural atelectasis by RP-EBUS and its 95% confidence interval will be estimated to accomplish the primary objective.
Up to 3 years
Atelectasis for each patient
Patients with at least 1 segment containing a new atelectasis will be determined to have atelectasis. Patients without atelectasis within any of the 8 segments will be determined to not have atelectasis. The proportion of patients identified as developing intraprocedural atelectasis by RP-EUS and its 95% confidence interval will be estimated to accomplish the primary objective.
Up to 3 years
Secondary Outcomes (3)
Common locations exhibiting atelectasis
Up to 3 years
Proportion of evaluated bronchial segments developing intraprocedural atelectasis
Up to 3 years
Patient characteristics associated with the presence of atelectasis
Up to 3 years
Study Arms (1)
Observational (bronchoscopy, RP-EBUS)
Patients undergo bronchoscopy per standard of care, RP-EBUS of the left and right lungs during bronchoscopy procedure, and RP-imaging over 3-5 minutes at the end of the bronchoscopy procedure.
Interventions
Undergo RP-EBUS
