Extensive Definition

In medicine, shifting dullness refers to a sign, elicited on physical examination, for ascites. If, on percussion, the region of dullness (denoting ascites) shifts when the patient is turned from supine position to side-lying, they probably have fluid in the abdomen. If the borders between tympanic and dullness remain the same, the person likely does not have ascites, or has less than 2 litres of fluid present
