One-Lung Ventilation
One-lung ventilation (OLV) is a thoracic anesthetic technique achieving selective lung isolation using double-lumen tubes or bronchial blockers. It enables surgical access by collapsing the operative lung while ventilating the other. Mastery requires fiberoptic confirmation, lung-protective ventilation (Vt 4–6 mL/kg), and a systematic algorithm to rescue hypoxemia from shunt and malposition.
