Abstract
PURPOSE: Fiberoptic bronchoscopy (FOB) and lung biopsy is an important diagnostic tool in patients with diffuse pulmonary infiltrates. However, these patients often have hypoxemic respiratory failure which makes the procedure risky. Noninvasive positive pressure ventilation (NIPPV) improves oxygenation in hypoxemic patients. We report the efficacy and safety of an innovative technique of NIPPV-assisted bronchoscopic lung biopsy (BLB) in hypoxemic patients with diffuse parenchymal infiltrates.
