Acoustic Waveform Respiratory Evaluation

Advancing Telemedicine in Pulmonology: Acoustic-waveform Respiratory Evaluation (AWARE) Via Sensing and Machine Learning on Smartphones

Who can join

Ages 8 to 70 · All sexes · Healthy volunteers welcome

Inclusion Criteria:

1. Age 8-70 years
2. Ability to perform spirometry and oscillometry
3. Signed informed consent (and assent for children as appropriate)
4. No respiratory or other major disease (for healthy controls), or physician-diagnosed asthma, COPD, CF, or other airway diseases

Exclusion Criteria:

1. Inability or unwillingness to perform AWARE, spirometry, or oscillometry
2. Acute or chronic illness that, at the judgement of investigators, may affect lung function and alter the results of AWARE or the reference PFTs (spirometry and AOS)

About the study

The study will evaluate the feasibility of using smartphone speakers and microphones to evaluate the caliber of the airways, detect airway obstruction, aid in airway disease diagnosis, and identify disease exacerbations.
