The goal of this pilot single-arm crossover trial is to investigate the feasibility and safety of using single-use flexible bronchoscopes (SUFB) for routine diagnostic and therapeutic interventional pulmonary procedures instead of reusable flexible bronchoscopes (RFB). The main questions it aims to answer are: Was a decision to crossover from SUFB to RFB (at the discretion of the clinical bronchoscopist) made ? Bronchoscopist's assessment of the SUFB for each procedure (using a Likert scale 0-10) including: 1. Overall assessment 2. Scope quality 3. Scope handling 4. Scope maneuverability 5. Tool compatibility 6. Suction 7. Lavage 8. Safety 9. Image quality Participants will undergo bronchoscopy with single use bronchoscopes.
