We also studied the propagation and rupture of simulated mucus plugs using carbopol 940 gels to investigate the source of crackling sounds which occur in lungs with an abnormal amount of liquid in the airways, congestive heart failure, or small airway inflammation. The non-Newtonian properties of ...

Conclusions “Velcro-type” crackles predict the presence of FILD and directly correlate with the extent of distinct radiologic features of pulmonary fibrosis. Such evidence provides grounds for further investigation of lung sounds as an early identification tool in FILD.Peer...
lung is different from that of the heart in some aspects. First, the lungs are much larger than the heart; and lung sounds should be recorded at multiple sites of both lungs for an accurate analysis. Second, the quality of lung sound is easily affected by the patient’s effort to ...
Rales, often termed as crackles in modern medical terminology, are abnormal lung sounds heard via stethoscope caused by the popping open of small airways and alveoli.
Methods In a population-based study, lung sounds were recorded at six auscultation sites and classified in participants aged 40 years or older. Inspiratory crackles were classified as 'early' or 'late and into the types' 'coarse' and 'fine' by two observers. A diagnosis of COPD was based ...
Among the lung fields with ILDs, the increased mean FCQVs were significantly associated with the presences of traction bronchiectasis (p=0.003) and honeycombing (p=0.004).Conclusions: We herein reported that FCQVs, determined by our innovative analyzing system of respiratory sounds, can be ...
Summary: A computer aided diagnostic system capable of analyzing respiratory sounds can be very helpful in detection of pneumonia, asthma and tuberculosis as the Respiratory sound signal carries information about the underlying physiology of the lungs and is used to detect presence of adventitious lung...
