Hamman's sign
text:
Hamman's sign is a medical sign consisting of a crunching, rasping sound, synchronous with the heartbeat, heard over the precordium in spontaneous mediastinal emphysema. It is thought to result from the heart beating against air-filled tissues. It is named after Johns Hopkins clinician Louis Hamman, M.D. This sound is heard best over the left lateral position. It has been described as a series of precordial crackles that correlate with the heart beat rather than respiration.
