This increase in sound exists because sound travels faster and thus with lower loss of intensity through liquid or solid ("fluid mass" or "solid mass," respectively, in the lung) versus gaseous (air in the lung) media. Whispered pectoriloquy is a clinical test typically performed during a medical physical examination to evaluate for the ...
Respiratory sounds, also known as lung sounds or breath sounds, are the specific sounds generated by the movement of air through the respiratory system. [1] These may be easily audible or identified through auscultation of the respiratory system through the lung fields with a stethoscope as well as from the spectral characteristics of lung sounds. [2]
To assess areas of tenderness, palpate areas of pain, bruises, or lesions on the front and back of the chest. Bruises may indicate a fractured rib, and tenderness between the ribs may indicate inflamed pleura. [14] Palpate any abnormal masses or structures on the front and back of the chest. Abnormal masses or sinus tracts may point to ...
Chest congestion is usually caused by excess mucus in the airways, says Meilan King Han, M.D., M.S., professor of medicine and chief of the Division of Pulmonary and Critical Care at the ...
Pectoriloquy is the increased resonance of the voice through the lung structures, so that it is clearly comprehensible using a stethoscope on the chest. It usually indicates consolidation of the underlying lung parenchyma. [1] Types include egophony and bronchophony. [2]
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.
Breath sounds are bronchial; Possible medium, late, or pan-inspiratory crackles; Vocal resonance is increased. Here, the patient's voice (or whisper, as in whispered pectoriloquy) can be heard more clearly when there is consolidation, as opposed to the healthy lung where speech sounds muffled. A pleural rub may be present. [4]
Crackles can be heard in people who have pneumonia, atelectasis, pulmonary fibrosis, acute bronchitis, bronchiectasis, acute respiratory distress syndrome (ARDS), interstitial lung disease or post thoracotomy or metastasis ablation. Pulmonary edema secondary to left-sided congestive heart failure and high altitude pulmonary edema can also cause ...
