Reliability and Validity of Computerized Adventitious Respiratory Sounds in People with Bronchiectasis.

ABSTRACT:

Background

Computerized adventitious respiratory sounds (ARS), such as crackles and wheezes, have been poorly explored in bronchiectasis, especially their measurement properties. This study aimed to test the reliability and validity of ARS in bronchiectasis.

Methods

Respiratory sounds were recorded twice at 4 chest locations on 2 assessment sessions (7 days apart) in people with bronchiectasis and daily sputum expectoration. The total number of crackles, number of wheezes and wheeze occupation rate (%) were the parameters extracted.

Results

28 participants (9 men; 62 ± 12 y) were included. Total number of crackles and wheezes showed moderate within-day (ICC 0.87, 95% CI 0.74-0.94; ICC 0.86, 95% CI 0.71-0.93) and between-day reliability (ICC 0.70, 95% CI 0.43-0.86; ICC
