Lung function was evaluated using several parameters, including forced vital capacity (FVC), total lung capacity (TLC), and carbon monoxide diffusing capacity (DLco). Nearly half (47%) of the participants were obese, and 27% showed signs of emphysema - a severe form of chronic obstructive pulmonary disease (COPD) - on chest CT scans. As part of the study, the healthcare providers were given several examples of what fine and coarse crackles may sound like.įine crackles can sound like Velcro strips being separated or the noise that comes from rubbing hair between fingers, while coarse crackles may sound like someone is walking on ice or squeezing a paper bag.Ī total of 290 patients, 58% of whom were men, were evaluated in the study.

Crackles-Crackles, or rales, are a scratch sound quality evident when fluid fills up in the alveolar and interstitial spaces.Diffuse or bilateral wheezes could mean upper airway bronchospastic disease or diffuse multifocal pneumonia Focal or unilateral wheezes typically indicate focal pneumonia.
