Dullness replaces the normal resonance of lungs when fluid or solid tissue replaces the air in the lungs (e.g. Too much air in the lungs makes the lung hyperresonant. Thus, breath sounds are louder with consolidation and lower decreased with pleural effusion, PTX, or emphysema. Sound travels faster through solids than through air and liquid. Emphysematous blebs and pneumothorax are hyperresonant to percussion. Pleural fluid is associated with a dull-to-flat percussion note, decreased-to-absent tactile fremitus, and decreased-to-absent breath sounds.Ī consolidation would be indicated by increased bronchial breath sounds and increased fremitus. Causes of decreased tactile fremitus include:ġ ) Unilateral: Bronchial obstruction with mucus plug or foreign object, Pleural effusion, PneumothoraxĢ) Diffuse: Muscular or obese chest wall, Chronic obstructive lung disease” Abnormal lung sounds such as stridor, rhonchi, wheezes, and rales, as well as characteristics such as pitch, loudness, and quality, can give important clues as to the cause of respiratory symptoms. The causes of increased tactile fremitus include: Pneumonia, Lung tumor or mass, Pulmonary fibrosis, Atelectasis. The sound, rhythm, and speed of your breathing can reveal a great deal. Any duplication or distribution of the information contained herein is strictly prohibited.“Tactile fremitus increases in intensity whenever the density of lung tissue increases, such as in consolidation or fibrosis, and will decrease when a lung space is occupied with an increase of fluid or air (e.g., pleural effusion, pneumothorax and emphysema).

Wheezing and other abnormal sounds can sometimes be heard without a stethoscope.Ī.D.A.M., Inc. They are most often heard when a person breathes out (exhales). High-pitched sounds produced by narrowed airways. Usually it is due to a blockage of airflow in the windpipe (trachea) or in the back of the throat. Wheeze-like sound heard when a person breathes. They occur when air is blocked or air flow becomes rough through the large airways. Rales can be further described as moist, dry, fine, and coarse. They are believed to occur when air opens closed air spaces. They are heard when a person breathes in (inhales). Small clicking, bubbling, or rattling sounds in the lungs. There are several types of abnormal breath sounds. Over-inflation of a part of the lungs ( emphysema can cause this).Air or fluid in or around the lungs (such as pneumonia, heart failure, and pleural effusion).

Using a stethoscope, the health care provider may hear normal breathing sounds, decreased or absent breath sounds, and abnormal breath sounds. Normal lung sounds occur in all parts of the chest area, including above the collarbones and at the bottom of the rib cage. The lung sounds are best heard with a stethoscope.
