Normal breath sounds are classified as vesicular, bronchovesicular, bronchial or tracheal based on the anatomical location of auscultation. [ 4 ] [ 3 ] Normal breath sounds can also be identified by patterns of sound duration and the quality of the sound as described in the table below: [ 4 ]
Resonance: Loud and low pitched. Normal lung sound. [15] Dullness: Medium intensity and pitch. Experienced with fluid. [14] A dull, muffled sound may replace resonance in conditions like pneumonia or hemothorax. Hyper-resonance: Very loud, very low pitch, and longer in duration. Abnormal. [14] Hyper-resonance can result from asthma or emphysema
Bronchophony may be caused by a solidification of lung tissue around the bronchi – which may indicate lung cancer – or by fluid in the alveoli, which may indicate pneumonia. However, it may also have benign causes, such as wide bronchi. As such, it is usually an indication for further investigation rather than the main basis of a diagnosis.
Normal resonance/ Resonant, the sound produced by percussing a normal chest. Impaired resonance (mass, consolidation) lower than normal percussion sounds. Dull (consolidation), similar to percussion of a mass such as a liver. Stony dull, the sounds produced on percussion from the pleximeter with no contribution from the underlying area.
Studies have shown that normal lung sounds have distinctive characteristics that can be differentiated from abnormal lung sounds, [6] thus supporting the potential clinical value of acoustic lung imaging. By using the VRI that simultaneously records the vibration energy from 40 points over 12 seconds and presents all of the derived information ...
In days before X-rays were discovered, the sound of swallowed liquids were auscultated over this triangle to confirm an oesophageal tumour. To better expose the floor of the triangle up of the posterior thoracic wall in the 6th and 7th intercostal space, a patient is asked to fold their arms across their chest , laterally rotating the scapulae ...
Usually spoken sounds of a whispered volume by the patient would not be heard by the clinician auscultating a lung field with a stethoscope. However, in areas of the lung where there is lung consolidation, these whispered spoken sounds by the patient (such as saying 'ninety-nine') will be clearly heard through the stethoscope. This increase in ...
Egophony (British English, aegophony) is an increased resonance of voice sounds [1] heard when auscultating the lungs, often caused by lung consolidation and fibrosis.It is due to enhanced transmission of high-frequency sound across fluid, such as in abnormal lung tissue, with lower frequencies filtered out.
