Expedited deflation of the nonventilated lung to achieve OLV

Expedited deflation of the nonventilated lung to achieve OLV
Denitrogenate both lungs by ventilating with either 100% O2 or a N2O/O2 mixture for several minutes prior to initiating OLV.
Apply low suction (20 cmH2O) until the nonventilated lung has collapsed well.
  • With a DLT, apply low suction via a suction catheter placed into the endotracheal lumen leading to the nonventilated lung.
  • With a BB, apply low suction via the suction channel lumen. Disconnect the anesthetic circuit and allow a prolonged expiration for 20 to 30 seconds, or until the ETCO2 falls to zero. Then begin OLV after inflating the cuff of the bronchial blocker under direct vision with the flexible intubating scope.
Use PCV during OLV to avoid peaks in airway pressure that occur during VCV to decrease the risk of inadvertent reinflation of the nonventilated lung.
After placement of a lung isolation device to achieve OLV, expedited deflation by one or more maneuvers can improve collapse of the nonventilated lung.
BB: bronchial blocker; DLT: double-lumen tube; N2O: nitrous oxide; O2: oxygen; OLV: one lung ventilation; PCV: pressure-controlled ventilation; VCV: volume-controlled ventilation.
