Indications and Contraindications

Indications for exible bronchoscopy are divided into diagnostic and therapeutic (Tables 2.1 and 2.2).

It is not uncommon that a diagnostic exible bronchoscopy becomes both diagnostic and therapeutic in the same session, depending on unexpected fndings that go undetected with preprocedure imaging modalities or a change in the patient’s condition.

Increasingly, therapeutic exible bronchoscopic interventions are being performed by pulmonologists. In our opinion, it is due to an increased number of dedicated Interventional Pulmonology training programs and the more recent innovations in this feld.

Flexible bronchoscopy, in general, has a great safety profle [1, 2]. Major complications such as bleeding, respiratory depression, cardiorespiratory arrest, arrhythmia, and pneumothorax occur in less than 1% of cases. Mortality is rare, with

Absolute Contraindications

•\ Life-threatening arrhythmia or hemodynamic collapse

•\ Profound refractory hypoxemia/inability to oxygenate patient during the procedure

•\ Lack of informed consent

•\ Lack of capable bronchoscopist •\ Lack of adequate facility
