Visual lung-sound characterization by time-expanded wave-form analysis.
TLDR
Time-expanded wave form analysis provides reproducible visual displays that allow documentation of the differentiating features of lung sounds and enhances the diagnostic utility of the sounds. Expand
Mechanism of inspiratory and expiratory crackles.
TLDR
The most likely mechanism of crackle generation is sudden airway closing during expiration and suddenAirway reopening during inspiration, which is quantitatively consistent with the so-called stress-relaxation quadrupole hypothesis of Crackle generation. Expand
Automated lung sound analysis in patients with pneumonia.
TLDR
The lung sound analyzer found significant differences between lung sounds in patients with pneumonia and in asymptomatic controls, and believes that the lung-sound data produced by the device will help to teach physical diagnosis. Expand
Clinical utility of chest auscultation in common pulmonary diseases.
TLDR
It is concluded that auscultatory differences exist among common pulmonary conditions and that statistical models based on auscULTatory data perform well in predicting diagnostic categories. Expand
Validation of an Automatic Crackle ( Rale ) Counter 1 , 2
Introduction Since the time of Laennec, clinicians have recognized that crackles heard on chest auscultation commonly indicate a lung disorder. Furthermore, the number of locations on the chest atExpand
Effects of low concentrations of asbestos. Clinical, environmental, radiologic and epidemiologic observations in shipyard pipe coverers and controls.
TLDR
It is emphasized that low concentrations of asbestos can lead to pulmonary fibrosis and supports the need for lower threshold limit values. Expand
Chest auscultation in the diagnosis of pulmonary asbestosis.
Prevalence of chronic respiratory disease. Asbestosis in ship repair workers.
TLDR
Findings reemphasize the need for control of asbestos in the work areas, as well as careful medical surveillance of workers exposed to asbestos, which are shown to be higher than current threshold limit values. Expand
Absence of respiratory effects in subjects exposed to low concentrations of TDI and MDI.
TLDR
Exposure of workers to extremely low levels of isocyanates is not associated with chronic respiratory symptoms or effects on ventilatory capacity, and the results suggest that isOCyanates can be controlled to the point of eliminating effects as measured by these techniques. Expand
