Comparison of Remote Camera Measures of Lung Function Compared to Standard Spirometry

This study plans to test a new non invasive way of measuring lung function and compare it to the current method of blowing into a spirometer.

Spirometry is an essential investigation for diagnosis and assessment of severity in people with Chronic Obstructive Pulmonary Disease (COPD) and other respiratory conditions, it is used in every respiratory unit and across primary care. It requires subjects to blow into a tube which measures volume and flow of expired air. It involves specialist equipment and training to perform and interpret. Not all patients are capable of performing spirometry, in particular children, frail, cognitively impaired and those experiencing a flare or exacerbation of symptoms. Remote lung function assessment technology has the potential to enable assessment of lung function in these groups of patients. In the future it is also hoped that it could be used to improve respiratory disease monitoring outside the healthcare environment such as in the patients home.

This new method uses the latest infra-red depth detection cameras to measure chest wall movement. (N.B this does not capture identifiable images). We would like to record participants chest wall movements while blowing into the spirometer.
