- Use Fio
2 of 1.0.
- Ventilate with a tidal volume of 68 mL/kg with PEEP 5 cm H2O.
- Respiratory rate to maintain PaCO2 between 35 and 45 mm Hg.
- Check the DLT position subsequent to lateral decubitus positioning.
- If peak airway pressure >40 mm Hg during OLV, malposition of the double-lumen tube must be considered.
- For arterial hypoxemia, apply CPAP 10 cm H2O to the nondependent lung (not during video-assisted thoracoscopy).
- If additional correction of arterial hypoxemia is necessary, add PEEP 510 cm H2O to the ventilated lung.
- Frequent recruiting maneuvers.
- Avoid fluid overload.
- TIVA may be preferable to inhalation anesthetics.
- If necessary, intermittently inflate and deflate the operated lung.
CPAP= continuous positive airway pressure; DLT = double lumen tube; Fio
2 = fraction of inspired oxygen; IV = intravenous; OLV= one-lung ventilation; PEEP = positive end-expiratory pressure; TIVA = total intravenous anesthetic.
