The most common cause of hypoxia during one lung ventilation is:
A i.e. Malposition of the double lumen tube - Malposition of a double lumen tube is usually indicated by poor lung compliance and low exhaled tidal volume Most common cause of hypoxemia during one lung ventilation is malposition of double lumen tube.Q Hypoxemia can also occur due to occlusion of tube & increased shunt fraction.
Malposition of the double lumen tube
Increased shunt fraction
Collapse of one lung
Soiling of lung by secretions
