Abstract

SE DISPONE UN METODO PARA PREDECIR UNA PROPIEDAD DE UNA MATERIA DE ORIGEN BIOLOGICO, TAL COMO UN FLUIDO BIOLOGICO, CONTENIENDO AGUA, EN UNA CONDICION DINAMICA DONDE EL FLUIDO BIOLOGICO PUEDA CONTENER APROXIMADAMENTE DOS COMPARTIMIENTOS DONDE UNO DE LOS COMPARTIMIENTOS TENGA UNA CANTIDAD PROPORCIONALMENTE MAYOR O MENOR DE AGUA QUE EL OTRO COMPARTIMIENTO TENIENDO LA PROPIEDAD DE INTERES. EL METODO IMPLICA EL ESTABLECIMIENTO DE UN CONJUNTO DE ADIESTRAMIENTO EN EL LUGAR (NIR) CON CUANTIFICACION INDEPENDIENTE DE LA PROPIEDAD DEL FLUIDO QUE UTILIZA TECNICAS CONOCIDAS. EL CONJUNTO DE ADIESTRAMIENTO SE ANALIZA MATEMATICAMENTE CONFORME A UNA CORRELACION DESARROLLADA MEDIANTE ANALISIS DE REGRESION DESPUES DEL EMPLEO DE UNA TECNICA DE PREPROCESAMIENTO TAL COMO UNA TRANSFORMACION DERIVADA MULTIPLE DE ESPECTROS O UNA PROPORDIONALIDAD DE DOS LONGITUDES DE ONDA EN LOS ESPECTROS. EL RESULTADO ES UNA ECUACION DE TRANSFORMACION MATEMATICA QUE CUANTITATIVAMENTE RELACIONA LAS INTENSIDADES ESPECTRALES EN LONGITUDES DE ONDA ESPECIFICAS CON LA PROPIEDAD DE INTERES. ESTA ECUACION DE TRANSFORMACION PUEDE APLICARSE A MUESTRAS DESCONOCIDAS PARA PREDECIR SUS PROPIEDADES, ELIMINANDO CON ELLO LA NECESIDAD DEL METODO DE REFERENCIA, SALVO PARA VALIDACION O RECALIBRACION. EL METODO PROPORCIONA PREDICCION RAPIDA Y EXACTA DE LA PROPIEDAD DE LA MUESTRA DESCONOCIDA, QUE PUEDE SER LA PROPIEDAD DE CONCENTRACION DE HEMOGLOBINA O HEMATOCRITO EN LA SANGRE TOTAL ANIMAL. OTROS ANALISIS DE PROPIEDADES EN EL FLUIDO BIOLOGICO TALES COMO SATURACION DE OXIGENO EN HEMOGLOBINA EN LA SANGRE TOTAL ANIMAL PUEDEN INCLUIRSE EN EL ANALISIS MATEMATICO PARA AFINAR MAS LA PREDICCION DE LA PROPIEDAD DE INTERES. TAMBIEN, SE DESCRIBE UN BUCLE DEL PACIENTE CON EL FIN DE MONITORIZAR LA PROPIEDAD DE INTERES CASI SIMULTANEAMENTE CON CAMBIOS EN ESA PROPIEDAD DE INTERES.
