Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.
