Percussion Technique (cont) •Liver span (6-12 cm): Start in chest, below nipple (mid-clavicular line) & move down –tone changes from resonant (lung) to dull (liver) to resonant (intestines) •Spleen –small, located in hollow of ribs –percussion over last intercostal space, anterior axillary line should normally be resonant – dullness suggests splenomegaly Palpation: assess tenderness with light and deep palpation, assess for guarding and rebound tenderness, palpate for liver, spleen, kidney and abdominal masses (including fecal mass). A liver span 2 to 3 cm larger or smaller than these values is considered abnormal. Percussion Technique Liver span is determined by physicians using a percus-sion technique.

Positive percussion is less convincing than palpation (+LR = 1.7 to 2.1 for percussion vs. 8.5 for palpation) [3]. The purpose of both palpation and percussion of the spleen is to look for splenic enlargement. ; Resonance is a lower-pitched and hollow sound (found in normal lungs). Percussion Technique (cont) •Liver span (6-12 cm): Start in chest, below nipple (mid-clavicular line) & move down –tone changes from resonant (lung) to dull (liver) to resonant (intestines) •Spleen –small, located in hollow of ribs –percussion over last intercostal space, anterior axillary line should normally be resonant – dullness suggests splenomegaly The liver weighs 1200 to 1400 g in the adult woman and 1400 to 1500 g in the adult man. Begin in the right midclavicular line below the level of the umbilicus and proceed as follows: Percuss upward over tympanic areas until a dull percussion sound indicates the lower liver border.
