Overview

Percussion

Definition:

Percussion is a method of "tapping" body parts during a physical examination with fingers, hands, or small instruments. The purpose is to evaluate the size, consistency, borders, and presence or absence of fluid in body organs.

Percussion of a body part produces a sound (like playing a drum) that indicates the type of tissue within the organ:

  • Lungs sound hollow on percussion because they are filled with air.
  • Bones and joints sound solid.
  • The abdomen sounds like a hollow organ filled with air, fluid, or solids.
