Using smartphone technology to evaluate airway conditions
Advancing Telemedicine in Pulmonology: Acoustic-waveform Respiratory Evaluation (AWARE) Via Sensing and Machine Learning on Smartphones
This study is testing if smartphone technology can help check lung health and spot breathing problems in both healthy people and those with asthma or COPD.

What this trial studies
This study aims to assess the feasibility of utilizing smartphone speakers and microphones to evaluate airway caliber, detect obstructions, and aid in diagnosing airway diseases such as asthma and COPD. By employing machine learning techniques, the study seeks to enhance pulmonary telemedicine, allowing for more accurate and reliable monitoring of lung function and disease exacerbations. Participants will include both healthy individuals and those diagnosed with various airway diseases, enabling a comprehensive evaluation of the smartphone-based approach. The study will focus on developing a method that can classify disease groups and estimate lung function adaptively.
Who should consider this trial
Good fit: Ideal candidates include individuals aged 8-65 with asthma, COPD, cystic fibrosis, or other airway diseases, as well as healthy controls.
Not a fit: Patients with acute or chronic illnesses that may affect lung function or those unable to perform the required tests may not benefit from this study.
Why it matters
Potential benefit: If successful, this approach could significantly improve remote monitoring and management of respiratory diseases, enhancing patient outcomes and quality of life.
How similar studies have performed: While the use of smartphone technology in healthcare is growing, this specific approach to pulmonary disease evaluation is novel and has not been extensively tested in prior studies.
Eligibility criteria
Show full inclusion / exclusion criteria
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)
