Clinical Feasibility of a Non-invasive Wearable Acoustic Device for Measuring Air trapping in COPD
Study Type/Phase: Observational
This study adopts the use of low-frequency ultrasound to enable a non-invasive, portable, easy-to-use method to measure air trapping for the early diagnosis of COPD and detection of disease exacerbation.
This study requires 1 visit with the study team that lasts approximately 4 hours. Subject will be subjected to the assessments below wearing the Sylvee device.
- Completing questionnaires
- Vital signs
- Lung function tests (Spirometry with Pre and Post Bronchodilator, DLCO and Body Plethysmography
- Metronome breathing
- 6-minute walk distance test
Who can participate?
No previous history of smoking nor diagnosed chronic lung conditions.
- Ages over 40 years old
- Documented diagnosis of COPD with preserved function of at least 80%
- History of smoking at least 10 cigarette-pack-years
