The liver being palpable 3 cm below the right costal margin,
midclavicular line, would be considered normal on inspiration when the
liver is pushed down into the abdominal cavity on inspiration, but is
abnormal on expiration. Findings to support hepatomegaly would be
more convincing if, by percussion, the liver span was >12 cm at the
midclavicular line. For patients with obstructive lung disease, air
trapping in the lungs may displace the liver downwards into the
abdominal cavity. The liver span and dullness to percussion refer to the
same measurement. Measurements of 6-12 cm at the mid‐clavicular line
and 4-8 cm at the midsternal line are considered normal.
