What is a pleural rub?
Pleural Rubs. Pleural rubs occur when two inflamed pleural surfaces rub against each other during respiration. This is often heard in pleurisy, or inflammation of the tissues that lie in the lungs and chest cavity. The sound may be continuous or broken and creaking or grating.
What is the sound of walking on snow?
It can be described as the sound of walking on fresh snow or rubbing leather together. The sound of pleural rubs occurs every time the patient inhales and exhales. Pleural rubs come and go, are not altered with coughing, can usually be localized to a specific location on the chest wall, and will stop when the patient holds their breath.

Summary
Lung sounds are part of the normal respiratory cycle. So-called bronchial sounds result from turbulent airflow that is generated within the normal trachea and larger airways. These sounds are relatively harsh and can be ausculted by placing a stethoscope over the windpipe.
What is the term for the voice over a consolidated lung?
The term used to describe the voice sounds heard over consolidated lung is bronchophony (also called vocal resonance). It can be determined through the stethoscope when the patient says “99”, usually just audible but becoming louder when the lung is consolidated. Pectoriloquy is abnormal transmission of the patient’s voice sounds through the chest wall so that they can be clearly heard through the stethoscope. The term used to describe whispered speech heard over consolidated lung (as in pneumonia), is whispering pectoriloquy. Bronchophony and whispering pectriloquy have the same implications as bronchial breathing i.e. consolidation or cavitation of the lung with improved transmission of sound. Aegophony is a form of bronchophony in which the spoken syllables have a peculiar nasal or bleating quality, and these arise from the transmission of sound through compressed lung just above a pleural effusion.
What is the ration of inspiratory phase?
They are soft, low pitched, and rustling in quality. The inspiratory phase lasts longer than the expiratory phase with a ration (I:E) of 2:1.
Why is auscultation important?
An important feature of auscultation is recording the intensity of the breath sound. Intensity can be reduced due to several factors: Weak sound generation and/or impaired transmission. Various causes are shallow breathing, airway obstruction, bulla, hyperinflation, pneumothorax, pleural effusion or thickening, and obesity.
What is a grating sound?
A discontinuous grating sound or creak in phase with breathing that occurs in the presence of pleural inflammation. Friction rubs are heard better when the stethoscope is applied firmly to the chest wall. Pleural rubs must be distinguished from similar sounds produced by movement of the scapula, ribs and thoracic musculature under the stethoscope. The latter disappear on repositioning of the stethoscope, changing pressure of application to the chest wall or by repositioning of the patient.
What is the difference between coarse crackles and fine crackles?
They are discontinuous, interrupted explosive sounds. Coarse crackles or crepitations are associated with bronchiectasis or resolving pneumonia, whereas fine crackles can be heard with either pulmonary oedema or interstitial fibrosis.
What is a pleural rub?
Pleural rubs must be distinguished from similar sounds produced by movement of the scapula, ribs and thoracic musculature under the stethoscope. The latter disappear on repositioning of the stethoscope, changing pressure of application to the chest wall or by repositioning of the patient.
What is a monophonic wheeze?
Monophonic wheezing consists of a single musical note starting and ending at different times. A local pathology-like bronchial obstruction by tumor, bronchostenosis by inflammation, mucus accumulation, or a foreign body can produce this sound. In case of rigid obstruction, the wheeze is audible throughout the respiratory cycle, and when the obstruction is flexible, wheeze may be inspiratory or expiratory.
