TABLE S1 Patient reported outcomes using St George’s Respiratory Questionnaire for COPD (SGRQ-C) and Cough and Sputum Assessment Questionnaire (CASA-Q). Scores range from 0 to 100, with lower values indicating improvement. 00269-2020.tableS1
VIDEO S1 Posterior view of lungs (right and left as shown), trachea on center line above the lungs and stomach below the left lung. The sequence of 2-min frames in the cine: 1–17 (i.e. first 34 min of scanning) followed by frames 21-22, 26-27, 31-32, 36-37 (CC), 41-42 (CC) and 46-47 (CC) (i.e. 10-min intervals after the first 34 min through a total of 94 min). Thus, it is not completely linear with time after the first 17 frames and controlled cough (CC) occurred during the last six cine frames. The cine clearly shows retrograde movement of activity from the trachea back into the lungs during the first hour of imaging (through frame 32) with cough enhancing clearance (CC) beyond that time/frame. 00269-2020.videoS1
