Abstract

UN DISPOSITIVO PARA LA DETERMINACION INDIVIDUAL IN VIVO DE LA FUNCION DE CONFORMIDAD C(CP) = DV/DP DEL SISTEMA VASCULAR AGUAS ABAJO DE UN VENTRICULO Y/O FLUJO DE SANGRE SISTEMATICA DE UN SER VIVO A PARTIR DE LA PRESION SANGUINEA P(T) Y UNA SALIDA CARDIACA DE REFERENCIA COREF. EL DISPOSITIVO COMPRENDE: A) UN SENSOR DE PRESION QUE DETERMINA CONTINUAMENTE LA PRESION P(T) EN LA AORTA O EN SUS PROSIMIDADES; B) UN ORDENADOR QUE B1) CALCULA LA PRESION MEDIA SANGUINEA MAP A PARTIR DE LA PRESION DE LA SANGRE P(T). B2) CALCULA LA RESISTENCIA SISTEMATICA R DEL CUERPO COMO R= MAP - CVP/COREF CVP ES UNA PRESION VENOSA CENTRAL ARBITRARIA QUE ES DETERMINADA O ESTIMADA, Y COREF ES UN VALOR DE REFERENCIA PARA EL DEBITO CARDIACO. B3) TOMA AL MENOS LA PRIMERA DIFERENCIAL DE LA PRESION SANGUINEA CON RESPECTO AL TIEMPO P(T) = DP/DT, Y B4) CALCULA LA FUNCION DE CONFORMIDAD C(P) AL MENOS A PARTIR DE P(T), P(T) Y R UTILIZANDO UN MODELO NO LINEAL.
