Percussion schedule:
Introduction


 

Role over mouse to demonstrate areas to be percussed, including the axilla.

Percussion is the art of tapping the body to learn from the resulting sound the condition of the parts beneath the tap. Usually the index or ring finger is used to tap the middle finger at its middle phalanx. Percussion is like beating a drum .If the drum is empty the sound will be different from if it is filled. Percussion of the chest is always resonant because of air within the lungs except in areas which contain the liver (hepatic dullness) and the heart (cardiac dullness). Percussion of the abdomen is always tympanitic. Other areas of the body are dull. Dullness is present in the chest in consolidation of lungs, but hyerresonant in pneumothorax. In the abdomen it is dull in ascites, but highly tympanitic in gaseous distension.
