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.
|
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. |
