coin test

An auscultatory test for pulmonary consolidation in which a coin is used as a pleximeter. A sound is produced by striking the coin with a hard object such as a screwdriver used as a plexor. The coin is placed over the area to be examined. If the lung below is consolidated the sound produced by striking the coin is transmitted with greater clarity than if it were filled with air. Obviously designed for the farmyard veterinarian. The companion animal specialist will use a proper plexor hammer and diascope.
