The aim of this study is to evaluate the usefulness of the new Ambu® aScope ™ 4 bronchoscope, in the usual practice of low complexity diagnostic bronchoscopy managed by bronchoscopists who meet the minimum training requirements (having performed 100 supervised procedures [ 10]) and maintenance of competition (with more than 25 bronchoscopies per year [10]).

Muticentric trial to evaluate three outcomes

1. Describe the experience of bronchoscopists performing low complexity bronchoscopic procedures with the Ambu® aScope ™ 4.
2. Collect the opinion of bronchoscopists about the technical characteristics of the device subject to study through a standardized questionnaire.
3. Analyze the quality of both microbiological and cytological samples obtained through the disposable bronchoscope.
