Diagnostic yield, safety, and impact of transbronchial lung biopsy in mechanically ventilated, critically ill patients: A retrospective study

Pulmonary infiltrates of variable etiology are one of the main reasons for hypoxemic respiratory failure leading to invasive mechanical ventilation. If pulmonary infiltrates remain unexplained or progress despite treatment, the histopathological result of a lung biopsy could have significant impact on change in therapy.
