Bronchoscopy is performed under local anesthesia, conscious sedation, or general anesthesia (full intubation), depending on the patient's general condition, the nature of the illness, and the scope of the procedure to be applied. The patient does not feel any pain during the procedure. In cases where full general anesthesia is not required, there is a possibility for the patient to experience mild coughing or a feeling of shortness of breath; however, such discomforts are generally minimized with local anesthesia applications, and most patients tolerate the procedure comfortably. The procedure is carried out using a thin, flexible device called a bronchoscope, which has a camera and light at its tip, inserted through the nose or mouth while the patient is in a sitting or lying position.
