An bronchial blocker (also called endobronchial blocker) is a device which can be inserted down a tracheal tube after tracheal intubation so as to block off the right or left main bronchus of the lungs in order to be able to achieve a controlled one sided ventilation of the lungs in thoracic surgery. The lung tissue distal to the obstruction will collapse, thus allowing the surgeon's view and access to relevant structures within the thoracic cavity.[citation needed]
Bronchial blockers are used to achieve lung separation and one lung ventilation as an alternative to double-lumen endotrachealtubes (DLT) and are the method of choice in children and paediatric patients for whom even the smallest DLTs might be too big.[1]
