The video starts at RB1 (bronchus to right cranial lobe). Collapse is evident with normal respiration. At 0:16, RB2 (right middle), RB3 (right caudal), and RB4 (accessory) come into view. Severe collapse of RB3 and RB4 can be seen particularly as the patient begins to cough. At 1:14, both mainstem bronchi can be seen from within the caudal trachea. Collapse of the trachea and mainstem bronchi were not observed at any time during the bronchoscopic exam. At 1:16, partial collapse of LB2 (left caudal) is seen.
