One lung ventilation (OLV) is a technique that allows isolation of the individual lungs under anaesthesia. Safe implementation of this technique requires an understanding of specialist airway equipment, and of the physiological changes that occur during the procedure.
It is necessary to emphasize that endobronchial intubation, with these specific airway adjuncts, and OLV, may significantly add to the anaesthetic risk, resulting from trauma to the airways, and failure of adequate ventilation.
Indications for One lung ventilation
There are four main indications for one-lung anaesthesia:
1. Isolation of the lungs
2. To improve surgical access
3. Greater control over ventilation
4. Unilateral bronchopulmonary lavage
