Abstract

EL SISTEMA DISPONE DE DOS LEDS (12,14) DE DOS LONGITUDES DE ONDA DIFERENTES QUE ILUMINAN EL TISU QUE CONTIENE EL FLUJO DE SANGRE ARTERIAL. UN FOTODIODO (16) RECIBE LUZ DESDE LOS LEDS Y PRODUCE SEÑALES ELECTRICAS (IR(T) RED(T)) QUE CONTIENEN COMPONENTES PULSATORIAS. LAS COMPONENTES DE DOS LONGITUDES DE ONDA SE SEPARAN Y LAS FORMAS DE ONDA SE PROCESAN BAJO PICOS DE SEÑAL (IR MAX) QUE SE DETECTAN EN EL FINAL DE LA DIASTOLE. LAS FORMAS DE ONDA SON ENTONCES INTEGRADAS SOBRE EL INTERVALO SISTOLICO, Y LAS INTEGRALES SE COMBINAN CON LOS VALORES DE LOS PICOS DE SEÑAL PARA DETERMINAR UN VALOR INDICE. EL VALOR INDICE SE USA PARA SELECCIONAR UN VALOR REPRESENTATIVO DE LA SATURACION DE OXIGENO PROCEDENTE DE UNA TABLEA INFORMATIVA.
