Abstract

Double Lumen Tube (DLT) and Bronchial Blocker (BB) are frequently used to provide One Lung Ventilation (OLV) in major thoraco-abdominal and spine surgeries. With advanced surgeries like Video Assisted Thoracic Surgeries (VATS), rapid and accurate placement of the DLT/Bronchial Blocker is necessary. Clinical examination includes inspection of chest movements and auscultation of breath sounds. These clinical methods remain important means of accurate placement of DLT/Bronchial blocker as a first confirmation test. However, these methods are subjective, and variability exists between individuals who are very common, and it fails to correctly identify the placement in 37% of the patients and requires repositioning by bronchoscopy [1].
