Predicting spirometry readings using cough sound features and regression
Objective : Spirometry is a commonly used method of measuring lung function. It is useful in the
definitive diagnosis of diseases such as asthma and chronic obstructive pulmonary disease (COPD).
However, spirometry requires cooperative patients, experienced staff, and repeated testing to ensure
the consistency of measurements. There is discomfort associated with spirometry and some patients
are not able to complete the test. In this paper, we investigate the possibility of using cough
sound analysis for the prediction of spirometry measurements. Approach : Our approach is based on
the premise that the mechanism of cough generation and the forced expiratory maneuver of spirometry
share sufficient similarities enabling this prediction. Using an iPhone, we collected mostly
voluntary cough sounds from 322 adults presenting to a respiratory function laboratory for pulmonary
function testing. Subjects had the following diagnoses: obstructive, restrictive, or mixed
pattern...
