The examiner also should note the timing of any abnormal breath sound
or when the sound occurs in the respiratory cycle.
Figure 1 demonstrates a graphic representation of breath sounds
obtained by means of the acoustic sensor based on the MEMS microphone.
Cough followed by dysopnea and choking were the main symptoms of the patients and decreased breath sound
on auscultation was the main sign identified in our study.
recordings were captured using a small microphone inserted into a Hans Rudolph breathing valve through the saliva port.
Our experiments show clear reduction of heart sounds from breath sounds
; moreover, the electronic processing will not result in any perceivable delay that may discourage physicians from using this stethoscope.
For example, bruits are masked by breath sounds
; and heart sounds may be masked by bowel sounds and patients' lung structure.
Physical examination showed diminished breath sounds
over the left hemithorax.
were not heard over the lower and middle zones of the right lung with dullness on percussion.
Pulmonary examination revealed diminished breath sounds
at the basal right hemithorax and the diaphragm was determined to be higher on the right by percussion.
over the right upper lung lobe were remarkably diminished.
MINNEAPOLIS--An automated analysis of tracheal breath sounds
while awake was predictive of obstructive sleep apnea judging from the findings of a small study.
I have heard that term before: "Chronic snufflers" are cats who have audible breath sounds
emanating from their upper airways.
In the example seen in Figure 1, breath sounds
and lung sounds are used to illustrate the problems faced without standardized definitions, data, formats, and structure.
