Bronchiole Alveolar Lavage (BAL)

BAL; a flexible catheter is placed in the suspect area of the lung. Saline is then released into the area and drawn back through the catheter to be used as a test sample to aid in diagnosing infection/pneumonia; may be performed by a camera (requires equipment, pulmonologist and technician) or blind (small, mini catheter) by a trained respiratory therapist or nurse.
