Endobronchial ultrasound (EBUS) is frequently used in pneumology for diagnostic procedures like mediastinal biopsies. This procedure is usually done under general anesthesia. Different methods of ventilation are used according to center and physician preferences. In this retrospective study, complications of 2 types of ventilation will be analyzed: * High frequency jet ventilation (HFJV) * Conventional intermittent positive pressure ventilation (IPPV) Descriptive statistics will be used to present the data. Both ventilation techniques will be compared after propensity score matching. For HFJV patients from 2019 will be analyzed and for IPPV patients from 2023, as the team changed its practice over time.
