Relationship Between Acoustic Breath Sounds and Spirometry

A Comparative Single Centre Study Assessing the Relationship Between Acoustic Breath Sounds as Measured by a Commercially Available Sound Recording Device Against Standard of Care (Spirometry) in the Assessment of Airflow Obstruction in Patients Who Plan to Undergo Spirometry Testing

Summary

The goal of this clinical trial is to assess whether wheeze as assessed by a commercially available wheeze monitor is comparable to lung function as measured during a spirometry test. The main questions it aims to answer are whether measures of airflow obstruction (FEV1, FEV1/FVC, PEF) correlate with wheeze score (Tw/Ttot%). Participants consenting to take part will undergo wheeze measurement prior to and during a spirometry test and will be asked to complete a series of symptom questionnaires.

Conditions

• Asthma COPD
