Bronchoalveolar lavage (BAL) involves obtaining a specimen from the lower respiratory tract for diagnosis of infection or distinguishing ARDS from pulmonary edema. It requires proficiency in bronchoscopy and should be guided based on thoracic imaging modalities. Collected specimen should be sent for quantitative culture, with a positive result identified as 104 or greater CFU/mL. Ideally, this procedure should be performed before initiation of antibiotics to optimize accuracy of obtained culture data.
