The patient was extubated and reintubated with a double-lumen endotracheal tube (Broncho-Cath; Mallinckrodt Medical; St. Louis, MO), with placement confirmed bronchoscopically. Individual standard ventilators (Puritan Bennett Models 7200 and 840; Mallinckrodt Medical) were used to ventilate each lung separately, without interventilator synchronization. The right lung ventilator was set to PCV of 50 cm H2O; rate, 16/min; I:E of 1:2; and no PEEP. The left lung ventilator was set to PCV of 30 cm H2O; rate, 10/min, I:E of 2:1; and PEEP of 10 cm H2O. Her BP normalized within minutes of instituting independent lung ventilation, with improvement of her ABG analysis at 6 h to pH 7.36; Pco2, 58 mm Hg; Po2, 185 mm Hg; and calculated bicarbonate, 32 mEq/L. She continued to receive aerosolized albuterol via both ventilator circuits and IV corticosteroids. Two days later, she was converted to a conventional single-lumen endotracheal tube, and 4 days later was extubated uneventfully. Four weeks after discharge, receiving maintenance therapy with fluticasone, salmeterol, and albuterol MDIs, she appeared well and spirometry findings were normal.
