In their study, conducted at Monash Lung and Sleep at Monash Medical Centre in Melbourne, 151 patients with stable COPD underwent state-of-the-art videofluoroscopy while drinking 100mL of thin oral liquid barium contrast solution.

All participants had a 10 pack-year or greater history of smoking, FEV1 less than 80% of predicted and FEV1/FVC ratio 0.7 or less.
