Subjects prescribed with the LibAirty system will be instructed to perform daily therapy sessions per standard device use recommendations. During the study period, subjects will be followed according to standard of care procedures and timelines for Bronchiectasis management. Clinical outcomes and healthcare resource utilization during the study period will be collected and compared to the 12-month period prior to study enrollment. Adherence to therapy will be evaluated by device recorded logs. Health related quality of life and subject satisfaction with the system will be evaluated by designated questionnaires, collected during clinic visits. Subjects will be followed for 12 months after starting therapy. Each subject will be required to complete a screening and enrollment visit, and any scheduled follow up visits according to standard of care timelines through 12 months (with data expected to be collected at 6 and 12 (±1m) months at minimum). Up to one hundred (100) subjects older than 21 years of age, with bronchiectasis who meet the entry criteria will be enrolled to the study, in up to ten (10) sites.
