Objectives

Narrative objectives1

We evaluate swallowing function in patients with chronic obstructive pulmonary disease (COPD) and prospectively study the relationships between swallowing function and prognostic factors.

Basic objectives2

Others

Basic objectives -Others

We evaluate swallowing function during eating property-adjusted test foods and during sleep in patients with COPD, and prospectively study the relationships between swallowing function and prognostic factors such as exacerbation, decline of lung function, and progression of emphysema based on CT images.

65

Results

Breathing-swallowing discoordination is strongly associated with frequent exacerbations of COPD. Strategies that identify and improve breathing-swallowing coordination may be a new therapeutic treatment for patients with COPD.

Baseline Characteristics

stable outpatients with COPD. Patients with an apparent swallowing disorder, clinically evident cerebrovascular diseases, dementia or a cardiac pacemaker were excluded.

Participant flow

We evaluated the number of COPD exacerbation incidents from 1 year before and 1 year after the recruitment visit (day 0).

Adverse events

None.

Outcome measures

Coordination between breathing and swallowing, CAT, FSSG, FILS, FOIS

Swallowing states during adjusted test foods eating and sleep in COPD patients are monitored using a non-invasive swallowing activity monitoring and analysis system that recognizes swallowing and assesses swallowing function by analyzing relationships among swallowing sound, laryngeal motion, and respiration.
