Abstract

Appareil d'anesthésie ventilatoire d'un patient par administration d'un gaz contenant du xénon gazeux avec un circuit principal de gaz (CP) en circuit ouvert ou fermé comportant une branche inspiratoire (16) et une branche expiratoire (18), des moyens d'alimentation (1 , 2) en xénon gazeux pour alimenter la branche inspiratoire (16) du circuit principal (CP), des moyens de détermination de concentration de xénon. Les moyens de détermination de concentration de xénon (S6 ; M1 ) comprennent au moins un capteur à fil(s) chaud(s) (S6-E ; M1-D) comportant au moins un fil conducteur de l'électricité en contact direct avec le flux gazeux contenant le xénon, des moyens de calcul (3 ; S6-D ; M1-C) coopérant avec le capteur à fil(s) chaud(s) pour déterminer la concentration de xénon (Xe%) dans le flux, des moyens de génération de courant électrique pour générer un courant dans au moins un fil chaud, et des moyens de mesure de tension aptes à mesurer au moins une valeur de tension (V) aux bornes d'au moins un fil chaud ou d'au moins une résistance agencée en série avec au moins un fil chaud. Les moyens de calcul coopèrent avec les moyens de mesure de tension de manière à déterminer la concentration de xénon (Xe%).
