Similarly one may ask, what does dull percussion sound like?

Resonant sounds are low pitched, hollow sounds heard over normal lung tissue. Dull or thudlike sounds are normally heard over dense areas such as the heart or liver. Dullness replaces resonance when fluid or solid tissue replaces air-containing lung tissues, such as occurs with pneumonia, pleural effusions, or tumors.

Beside above, what is stony dullness? Stony dullness – this suggests the presence of a pleural effusion. Hyper-resonance – the opposite of dullness, suggestive of decreased tissue density – e.g. pneumothorax. Percuss the chest. Percuss the chest.

How do you do percussion?

Method Of Exam

Keep the middle finger firmly over the chest wall along intercostal space and tap chest over distal interphalangeal joint with middle finger of the opposite hand. The movement of tapping should come from the wrist.

What does ascites sound like?


One technique for evaluating ascites is assessment of shifting dullness. In the ascitic abdomen, gas-filled bowel loops float to the top while the ascitic fluid falls to the dependent portion of the abdomen. As a result, percussion notes are tympanitic over the bowel loops and dull over the surrounding fluid.

Is Shifting dullness normal?

If the fluid causing the dullness was not free, then the air-fluid level would not move. Shifting dullness is usually present if the volume of ascitic fluid is greater than 1500 ml. In some cases, the ascites collide to form a bigger ascites.

What does fluid in lung sound like?


Crackles are the sounds you will hear in a lung field that has fluid in the small airways. Coarse crackles sound like pouring water out of a bottle or like ripping open Velcro.

Is tactile Fremitus normal?

Increased fremitus may indicate compression or consolidation of lung tissue, as occurs in pneumonia. Normal findings on palpation include: normal chest size and shape, tactile fremitus over the mainstem bronchi in front and between the scapulae in the back of the chest.

What does a pleural effusion sound like?

Common signs of pleural effusion are asymmetric chest expansion, asymmetric tactile fremitus, dullness to percussion, absent or diminished breath sounds, and rubs. The larger the effusion, the more sensitive these signs are.

What is tactile Fremitus?


Fremitus. In common medical usage, it usually refers to assessment of the lungs by either the vibration intensity felt on the chest wall (tactile fremitus) and/or heard by a stethoscope on the chest wall with certain spoken words (vocal fremitus), although there are several other types.

What is the difference between auscultation and percussion?

The Greek physician Hippocrates used auscultation (from the Latin for "listen") as a diagnostic technique. In percussion, the doctor taps parts of the patient's body with his or her fingers or with a hammer-like instrument called a "percussor".
