<span lang="EN-GB">Lung sound is one indicator of abnormalities in the lungs and respiratory tract. Research for automatic lung classification has become interests researchers because disease diseases with most sufferers world. The use sounds as a source information ease data acquisition auscultation standard method examining pulmonary function. This study simulated potential Higuchi frac...

Chronic obstructive pulmonary disease (COPD) is a major public health concern across the world. Since it an incurable disease, early detection, and accurate diagnosis are very crucial for preventing progression of disease. Lung sounds provide reliable prognoses identifying respiratory diseases. Recently, Altan et al. recorded 12-channel real-time lung sound dataset, namely RespiratoryDatabase@T...

In this paper we develop and study numerically a model to describe some aspects of sound propagation in the human lung, considered as a deformable and viscoelastic porous medium (the parenchyma) with millions of alveoli filled with air. Transmission of sound through the lung above 1 kHz is known to be highly frequency-dependent. We pursue the key idea that the viscoelastic parenchyma structure ...

Visual and auditory analysis of respiratory sound signals promises improved detection of certain types of lung diseases. LabVIEW software was used to design a system that monitors the respiratory activity of the patient. The program developed calculates the respiratory rate, displays the time expanded waveform of the lung sound, and computes the fast Fourier transform and short-time Fourier tra...

when teaching to our housestaff trainees thoracocentesis that does not rely on chest percussion, namely, clavicle tapping with posterior chest auscultation. Stated simply, this technique takes advantage of the sound transmission characteristics of the inflated lung and the loss of sound transmission caused by the interposition of a layer of fluid between the air-filled lung and the chest wall. ...

Even in patients with clinically stable asthma with normal lung function, the airways are characterized by inflammatory changes, including mucosal swelling. In order to investigate whether lung sounds can distinguish these subjects from normal subjects, we compared lung sound characteristics between eight normal and nine symptom-free subjects with mild asthma. All subjects underwent simultaneou...

Ultrasound (US) is an ideal diagnostic tool for paediatric patients owning to its high spatial and temporal resolution, real-time imaging, lack of ionizing radiation bedside availability. In the current World Federation Societies Ultra-sound in Medicine Biology (WFUMB) paper series so far (part I) topic has been introduced technical require-ments explained. present use US lung analysed. Lung di...
