family

The family was traditionally committed to the medical profession, but his father had not completed his medical degree, but had become a postmaster in Saint-Germain-en-Laye . His father took Potain into the woods of Saint-Germain and taught him everything he knew about grammar, literature and science, from his mother he learned the German language.

education and profession

Since funds for a school education were not available, Potain learned completely independently, was accepted at the University of Paris and achieved a first successful degree here. At first he wanted to deal with the natural sciences and mechanics, but then turned to medicine . After graduating, he worked in the clinics of Paris ( internal ) from 1848 . During the great cholera - epidemic (1849) Potain medical assistant was at the Salpetriere . There he fell ill with cholera himself, recovered, fell ill again and survived.

In 1853 Potain received his doctorate from the University of Paris and then took a position as assistant to Jules Gabriel François Baillarder (1806-1891) in the madhouse of Ivry. In 1856 he worked again in Paris at the clinic of Jean-Baptiste Bouillaud (1796-1881) as chief physician and in other hospitals ( des Ménages , Sainte-Antoine , Hôpital Necker ). He also took on minor teaching positions at the university. In 1861 Potain was admitted to all hospitals ( Médecin des hôpitaux ) and was appointed Associate Professor of the Medical Faculty of the University of Paris ( Professeur agrégé ).

From 1882 he worked at the Hôpital de la Charité , where he stayed until his retirement in 1900. Potain died in 1901 of complications from aortic stenosis .

power

Potain dealt not only with methods of pulse recording , but also pointed to the close relationship of tricuspid - regurgitation and circulatory disorders as well as the liver -Pulsation out. He distinguished between different types of cardiac gallop rhythm, explained the mechanism of the cardiac impulse and recognized the throbbing sound of the second heart sound in syphilitic aortitis .

Enthusiastically it greeted the Sphygmo manometer of Basch and developed in 1889 to a usable in clinical operation instrument further. The use of his blood pressure measurement led him to further discoveries: He showed that Bright's disease (parenchymatous nephritis ) is associated with hypertension , discovered hypertension in other pathological conditions and as the cause of cardiac hypertrophy in renal arteriosclerosis .

He improved a device for counting the red blood cells (Malassez hematometer) and constructed an aspiration apparatus that worked with a vacuum pump . In patients with extreme shortness of breath , he performed a thoracentesis , removed the fluid with his aspirator, and connected another self-made device that gradually supplied air again.

Potain was a member of the Académie de Médecine (1883), the Académie des Sciences (1893) and commander of the Legion of Honor (1895). In the 19th arrondissement of Paris a street is named after him ( Rue du Docteur Potain ).
