Brief summary
In this study, the investigators want to find out whether robot-assisted bronchoscopy also works with moderate sedation (Propofol), as is already used in standard bronchoscopies. The study is being conducted as a pilot study. This means that it is an initial test run for a scientific investigation. The investigators are testing on a small scale whether the intervention works as predicted before a larger study is conducted.
Interventions
In this study, patients will undergo a robotic-assisted bronchoscopy under moderate sedation with propofol. While the use of propofol as a sedative is common for manual bronchoscopies, robotic-assisted bronchoscopy is only permitted under general anesthesia. In the study intervention, the investigators want to test the feasibility of the combination of robotic-assisted bronchoscopy under propofol.

Eligibility
Inclusion criteria
* informed consent signed by the subject * aged at least 18 years * scheduled for bronchoscopy with moderate sedation and tracheal intubation in order to obtain at least 1 specimens of the lung via transbronchial biopsy * necessary periinterventional laboratory examinations needed for the bronchoscopy * judgement of the subject
Exclusion criteria
* endobronchial lesion causing lobar atelectasis * inability or contraindications to undergo bronchoscopy (e.g. severe cardiopulmonary diseases, coagulation disorders, intolerance to anesthesia or endoscopic operation, psychiatric disorders or severe neurosis) * pregnant or lactating women
