![]() presuming the lung sound amplitude pattern to be bilaterally symmetric. It is also customary to compare the lung sound intensity of one area over the chest wall with that of the comparable area on the opposite side, 4. Respiratory rate is 16 breaths/minute, unlabored, regular, and inaudible through the nose. Symmetrical anterior and posterior thorax. Denies past or current respiratory illnesses or diseases. Abstract To characterize lung sounds objectively, we examined, by means of time-amplitude plots, selected tape recordings of auscultatory phenomena considered by six observers to be typical of thos. ![]() Google Scholar Shykoff BE, Ploysongsang Y, Chang HK. The frequency spectrum and the amplitude of sounds, i.e. The relationship between airflow and lung sound amplitude in normal subjects. Respiratory sounds contain significant information on physiology and pathology of the lungs and the airways. Patient denies cough, chest pain, or shortness of breath. Lung sound analysis for continuous evaluation of airflow obstruction in asthma.
