Abstract

SE DESCRIBE UN PROCEDIMIENTO Y UN DISPOSITIVO PARA LA DETERMINACION DE PARAMETROS HEMODINAMICOS DURANTE UN TRATAMIENTO EXTRACORPORAL DE LA SANGRE, EN EL CUAL LA SANGRE SALE A UN DIALIZADOR (10) O A UN FILTRO DEL DISPOSITIVO DEL TRATAMIENTO SANGUINEO A TRAVES DE LA RAMA ARTERIAL (20) DEL CIRCUITO EXTRACORPORAL (9) DEL DISPOSITIVO DEL TRATAMIENTO SANGUINEO (7), EL CUAL ESTA EN COMUNICACION DE FLUIDOS CON LA PARTE ARTERIAL (21) MEDIANTE UNA FISTULA (6); Y VUELVE A TRAVES DE LA PARTE VENOSA (23) DEL CIRCUITO EXTRACORPORAL, QUE ESTA EN COMUNICACION DE FLUIDOS CON LA PARTE VENOSA (23) DE LA FISTULA (6). SE MIDE LA TEMPERATURA T{SUB,A} EN LA RAMA ARTERIAL (20) DEL CIRCUITO EXTRACORPORAL (9)CON VARIACION DEL FLUJO SANGUINEO, MANTENIENDO CONSTANTE LA TEMPERATURA T{SUB,V} DE LA RAMA VENOSA (22) DEL CIRCUITO EXTRACORPORAL. A PARTIR DE LOS PARES DE VALORES MEDIDOS DE LA TEMPERATURA ARTERIAL T{SUB,A} Y DEL FLUJO SANGUINEO EXTRACORPORAL Q{SUB,B} SE DETERMINAN LOS PARAMETROS SEGUN UNA FUNCION PREDETERMINADA T{SUB,A}(Q{SUB,B}) QUE RELACIONA LA TEMPERATURA EN LA RAMA ARTERIAL DEL CIRCUITO EXTRACORPORAL (9) CON EL FLUJO SANGUINEO Q{SUB,B}, QUE SIRVEN PARA DETERMINAR EL FLUJO DE LA FISTULA Q{SUB,F} Y/O LA TEMPERATURA CORPORAL T{SUB,B} Y/O EL VOLUMEN CARDIACO POR MINUTO CO.
