Absent or decreased sounds can mean: Air or fluid in or around the lungs (such as pneumonia, heart failure, and pleural effusion) Increased thickness of the chest wall. Over-inflation of a part of the lungs (emphysema can cause this)
What causes dullness to percussion?
Dullness replaces resonance when fluid or solid tissue replaces air-containing lung tissues, such as occurs with pneumonia, pleural effusions, or tumors. Hyperresonant sounds that are louder and lower pitched than resonant sounds are normally heard when percussing the chests of children and very thin adults.
What do you do when you hear diminished breath sounds?
If you are unsure of what you are hearing through the stethoscope, or if breath sounds are diminished, ask him/her to breathe deeper and/or open the mouth wider. Perhaps ask him to breath faster; that may enhance the quality of the sounds you are hearing.

Note when in the respiratory cycle the wheeze occurs; usually louder in expiration.Can lung sounds be diminished but clear?
You can have clear lungs ounds with COPD too. After using a bronchodilator, diminished lung sounds may become clear. Or, sometimes, as airways open up, wheezing may occur. This we consider good, as it means air is moving better, and so wheezing can now be heard.
What are abnormal breath sounds called?
Adventitious sounds are the medical term for respiratory noises beyond that of normal breath sounds. The sounds may occur continuously or intermittently and can include crackles, rhonchi, and wheezes.

Crackles (Rales) Crackles are also known as alveolar rales and are the sounds heard in a lung field that has fluid in the small airways. The sound crackles create are fine, short, high-pitched, intermittently crackling sounds. The cause of crackles can be from air passing through fluid, pus or mucus.
What does pleurisy sound like?Pleural Rubs 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. It can be described as the sound of walking on fresh snow or rubbing leather together.

What does rubbing lung sounds mean?
A pleural friction rub is an adventitious breath sound heard on auscultation of the lung. The pleural rub sound results from the movement of inflamed and roughened pleural surfaces against one another during movement of the chest wall.
Can lung crackles be normal?
Wheezes and crackles are well-known signs of lung diseases, but can also be heard in apparently healthy adults. However, their prevalence in a general population has been sparsely described.

What is Rhonchi?
Rhonchi, sometimes also called low-pitched wheezes or coarse crackles, are nonrepetitive, nonmusical, low-pitched sounds frequently produced during early inspiration and expiration that usually are a sign of turbulent airflow through secretions in large airways.
What lung sounds normal?

A decrease in breath sounds and a change in their quality may allow your doctor to diagnose a pleural effusion.
What is pleural inflammation?

Common causes of pleurisy include bacterial and viral infections which can lead to pneumonia. Other causes of pleurisy include a pulmonary embolus, cancer and trauma to the chest wall.
What do COPD lungs sound like?
Rhonchi. These low-pitched wheezing sounds sound like snoring and usually happen when you breathe out. They can be a sign that your bronchial tubes (the tubes that connect your trachea to your lungs) are thickening because of mucus. Rhonchi sounds can be a sign of bronchitis or COPD.
What causes expiratory wheeze?
People may experience expiratory and inspiratory wheezing from lung conditions, such as asthma or COPD. Temporary conditions, such as respiratory infections, can also cause both types of wheezing. Expiratory wheezing is more common and may be a result of a mild infection affecting the airways.
