Indirect auscultation

Japanese: 《間接聴診法》 - かんせつちょうしんほう

…He made a wooden tube and named it stéthoscope, combining the Greek words stēthos (chest) and skopos (to look). He then auscultated a large number of cases, recorded the sounds, and compared them with the findings of postmortem autopsies. In 1919, he published a paper entitled “On Indirect Auscultation, or, Chiefly, the Diagnosis of Diseases of the Lungs and Heart by this New Method” (abbreviated as “Indirect Auscultation”), establishing the basis of today’s auscultation method using a stethoscope. For the next century, until the discovery of X-rays, indirect auscultation, along with percussion, was the only method for examining the chest. …

The stethoscope was introduced to Japan in 1848 (Kaei 1).
