Description
determina primero el valor de la resistencia y así los coeficientes de cálculo de la saturación adecuados para el valor de las longitudes de onda de los LEDs en la sonda. [0005] Se han propuesto otros mecanismos de codificación en las patentes estadounidenses nº 5.259.381, 4.942.877, 4.446.715, 3.790.910, 4.303.984, 5 4.621.643, 5.246.003, 3.720.177, 4.684.245, 5.645.059, 5.058.588, 4.858.615 y
4.942.877. La patente '877 en particular revela el almacenamiento de una variedad de datos en una memoria de un sensor de pulsioximetría, incluyendo los coeficientes para una ecuación de saturación para oximetría. [0006] Los sensores de pulsioxímetros de Nellcor están codificados con un valor de
10 resistencia (RCAL) que corresponde a la longitud de onda o longitudes de onda del/de los LED/-s en el emisor, como se describe en la patente nº 4.700.708. Los instrumentos de pulsioxímetro de Nellcor leen este valor de codificación de la resistencia y lo utilizan como un indicador a una tabla de consulta que contiene el conjunto adecuado de coeficientes para ese sensor para calcular la saturación de
15 oxígeno arterial (SpO2). La función que convierte la ratio R (también conocida como la
"ratio de ratios" o "rat-rat") de modulación de la señal IR y rojo medida en un valor de saturación calculado se deriva de la forma básica de la ley de Lambert-Beer:
donde I1 e I2 se refieren a las señales de luz detectadas en dos puntos diferentes en el ciclo cardíaco, y �s se refiere a las propiedades de absorción de la luz características de la hemoglobina oxigenada y desoxigenada. Cuando se resuelve
para la saturación (S), el resultado toma la siguiente forma:
[0007] La ecuación 2 puede simplificarse más para requerir únicamente tres constantes (por ejemplo, dividiendo cada constante por c2), pero se usará como se 30 muestra para el resto de la descripción. Aunque se basen en la teoría, las cuatro constantes c1- c4 se determinan de forma empírica. Los valores teóricos de las constantes son insuficientes principalmente debido a la complejidad de dispersión de
la luz y óptica del sensor. Los valores de los conjuntos de constantes (c1 hasta c4) varían con cada bin de codificación de la resistencia (cada "bin" corresponde a un margen de diferentes longitudes de ondas de LED caracterizadas). Se proporcionan
múltiples conjuntos de coeficientes (bins) en una tabla de consulta en los oxímetros de Nellcor. Cuando los valores de SpO2 calculados según la Ec. 2 son inferiores al 70%, se utiliza un valor revisado de SpO2 usando una función lineal:
donde ambos c3 y c6 varían con el valor de codificación de la resistencia. Se ha descubierto que esta función lineal ajusta mejor el spO2 (la saturación de oxígeno arterial medida por el pulsioxímetro) con el SaO2 (el valor real de saturación de oxígeno arterial, medido directamente en una muestra de sangre) en observación realizada a bajas saturaciones. [0008] Una limitación de este método es que la correcta calibración del sensor de
pulsioxímetro puede lograrse únicamente si la relación entre la ratio de modulación de
la señal (R) y la SaO2 de la sangre se ajusta a uno de los conjuntos de coeficientes de calibración precodificados. [0009] Otra limitación de este método es que la relación entre R y SaO7 del sensor de
pulsioxímetría puede no ser lineal en un región de baja saturación, o que el punto de
corte puede no estar situado de manera óptima en el 70% SpO2. [0010] Otra limitación más del método de la técnica precedente es que la relación funcional entre la verdadera saturación de oxígeno arterial y las señales medidas puede no ajustarse a una sola función en el espectro completo del margen de medición. [0011] Se define un sistema según la invención en la reivindicación 1. Algunas características preferidas se definen en las reivindicaciones dependientes.
RESUMEN DE LA INVENCIÓN
[0012] La presente invención aprovecha una memoria en el sensor para proporcionar un rendimiento mejorado. Se almacenan múltiples conjuntos de coeficientes. Los múltiples conjuntos se aplican a diferentes márgenes de valores de saturación para proporcionar un mejor ajuste rompiendo la relación de R a SpO2 en diferentes trozos, descritos cada uno por una función diferente. Las diferentes funciones pueden ser también fórmulas respectivas para determinar la saturación de oxígeno. [0013] El sensor también almacena una variable entre las dos funciones usadas para la saturación de oxígeno. Las dos funciones podrían ser bien fórmulas separadas o bien la misma fórmula con diferentes coeficientes. Esto permite la optimización a un valor diferente del valor de corte del 70% de la técnica precedente. [0014] En otro aspecto de la presente invención, el sensor puede almacenar más de un punto de corte para crear más de dos funciones que describen la relación de R a SpO2. [0015] En otro aspecto más de la presente invención, se utiliza una función spline, con corte de la relación de R a SpO2 en un número arbitrario de regiones. [0016] Cada uno de los métodos descritos mejoran el ajuste entre la función matemática seleccionada y la saturación de oxígeno arterial cortando la relación en subconjuntos de todo el margen medido completo y determinando los coeficientes óptimos para cada margen. El ajuste de spline, en este contexto, corta de forma similar el margen de medición completo en subconjuntos para describir de forma eficiente la relación numérica entre el parámetro del tejido subyacente de interés y las señales reales que se usan para estimar este valor. [0017] Para una mejor comprensión de la naturaleza y ventajas de la invención, se hará referencia a la siguiente descripción en conjunción con los dibujos adjuntos.

DESCRIPCIÓN DE LOS MODOS DE REALIZACIÓN ESPECÍFICOS
Monitor/lector de sensor
[0019] La Fig. 1 es un diagrama de bloque de un modo de realización de la invención. La Fig. 1 muestra un pulsioxímetro 17 (o lector de sensor) que está conectado a un sensor no invasivo 15 unido al tejido del paciente 18. La luz de los LEDs 14 del sensor pasa por el tejido del paciente 18 y tras ser transmitida a través o reflejarse desde el tejido 18 la luz es recibida por un fotosensor 16. Se pueden usar dos o más LEDs dependiendo del modo de realización de la presente invención. El fotosensor 16 convierte la energía recibida en una señal eléctrica, que se introduce después en el amplificador de entrada 20. [0020] Se pueden usar fuentes de luz distintas de los LEDs. Por ejemplo, se pueden usar láseres, o podría usarse una fuente de luz blanca con filtros de longitud de onda adecuada bien en el extremo de transmisión o bien en el extremo de recepción. [0021] La Unidad de Procesamiento de Tiempo (TPU, en inglés) 48 envía señales de control a la unidad de LED 32, para activar los LEDs, normalmente de forma alterna. De nuevo, según el modo de realización, la unidad puede controlar dos o cualquier número adicional de LEDs deseados. [0022] La señal recibida del amplificador de entrada 20 se pasa a través de dos canales diferentes mostrados en el modo de realización de la Fig. 1 para dos longitudes de onda diferentes. De modo alternativo, podrían usarse tres canales para tres longitudes de onda diferentes, o N canales para N longitudes de onda. Cada canal incluye un conmutador analógico 40, un filtro de paso bajo 42, y una convertidor de analógico a digital (A/D) 38. Las líneas de control de la TPU 48 seleccionan el canal apropiado en el momento en el que el LED correspondiente 14 está siendo accionado, en sincronización. Un módulo de series en cola (Queued Serial Module, QSM) 46 recibe los datos digitales de cada uno de los canales por medio de las líneas de datos
79. La CPU 50 transfiere los datos desde el QSM 46 a la RAM 52 a medida que el QSM 46 se llena periódicamente. En un modo de realización, el QSM 46, la TPU 48, la CPU 50 y la RAM 52 son parte de un circuito integrado, como un microcontrolador.
Memoria del sensor
[0023] El sensor 15, que incluye el fotodetector 16 y los LEDs 14, tiene un memoria 12 del sensor asociada al mismo. La memoria 12 está conectada a la CPU 50 en el lector del sensor o monitor 17. La memoria 12 podría empacarse en un cuerpo del sensor 15
o en un enchufe eléctrico conectado al sensor. [0024] La Fig. 2 es un ejemplo de un gráfico de la ratio de ratios (R) en el eje X frente a la saturación de oxígeno (SaO2) en el eje Y. Se muestra un punto de corte 52. En la técnica precedente, se predefinió el punto de corte del 70% en el software del monitor. A la derecha del punto de corte (saturaciones de oxígeno de entre 70-100%) se usó una fórmula con cuatro coeficientes. A la izquierda del punto de corte en la técnica precedente, se usó una ecuación lineal con dos coeficientes. La presente invención proporciona una mayor flexibilidad y exactitud utilizando una fórmula no lineal de la parte de la curva a la izquierda del punto de corte 52. Mediante el uso de un chip de memoria en el propio sensor, es posible almacenar estos coeficientes en el chip de memoria, así como los coeficientes separados para valores de saturación superiores. [0025] En otro modo de realización de la invención, el punto de corte 52 puede almacenarse en el chip de memoria, y puede elegirse para optimizar el ajuste de curva para los dos conjuntos de coeficientes. En otras palabras, puede obtenerse un mejor ajuste a las dos curvas si el punto de corte es 68%, por ejemplo. En un modo de realización alternativo, pueden usarse múltiples puntos de corte y curvas. Además, en lugar de usar la misma fórmula, pueden usarse fórmulas diferentes para las secciones diferentes en otro modo de realización. [0026] La Fig. 3 ilustra los contenidos de la memoria del sensor 12 de la Fig. 1. Como se muestra, en una primera sección de la memoria 54 se almacena un primer conjunto de coeficientes. Una segunda parte de memoria 56 almacena un segundo conjunto de coeficientes. Finalmente, en una tercera sección de memoria 58, se almacena el punto de corte 52. Se pueden almacenar diferentes combinaciones de estos elementos en diferentes memorias. Por ejemplo, podría excluirse el punto de corte de algunas, y en otras podría proporcionarse un punto de corte con solo un conjunto de coeficientes (con el otro conjunto de coeficientes en el monitor). Alternativamente, el punto de corte puede determinarse por un número modelo del sensor que se almacena en la memoria, o algún otro valor de identificación.
Ecuación :
[0027] En un modo de realización, se utiliza una forma mejorada de la función curvilínea. En lugar de usar la Ec. 3 (lineal) en la región de saturación inferior, se usa la Ec. 2 (no lineal) para ambas las regiones de saturación superiores e inferiores. El punto de corte que define cuando cambiar los coeficientes de un conjunto de la región superior a un conjunto de la región inferior se define mediante otro coeficiente. El punto de corte puede programarse bien como un valor de R, o bien como un valor de SpO2. Con el punto de corte definido como un valor de R, el algoritmo pasa a ser: Ajuste de curva
[0028] El ajuste de curva a múltiples regiones sigue la misma metodología que el ajuste a una sola región. Dicho simplemente, los datos se dividen en regiones separadas y se determinan los coeficientes para cada región de forma separada. En el mercado hay programas de software disponibles, (por ejemplo, Mathcad, (Mathsoft, Inc, Cambridge, MA). El proceso también puede encontrarse en, por ejemplo, Data Reduction and Error Analysis for the Physical Sciences (Philip Beviyton, McGraw-Hill, New York 1969, Ch. 11 - Least squares fit to an arbitraty function).
Ajuste de spline
[0029] Un modo de realización alternativo utiliza un ajuste de spline (curva), o interporlación de orden superior o lineal a un conjunto prefedinido de SpO2 frente a
valores de R ("nudos"). Un "nudo" es un término de la técnica en el ajuste de spline que se refiere a un par x-y que corresponde a un nodo en una línea, con un número de dichos nudos definiendo la línea. El ajuste de spline es una técnica de interpolación. [0030] Por ejemplo, los valores de R en valores específicamente definidos de SpO2 se
almacenan en la memoria del sensor. Este sería un ejemplo de lo anterior:
SpO2= 100 95 90
Alternativamente, aunque de forma menos preferible, la variable independiente podría intercambiarse:
R = 0,5 0,6 0,7
a) Solo los valores en negrita (p.ej., a, b y c) necesitan almacenarse con valores espaciados preseleccionados y fijos de SpO2 (espaciados de forma
equitativa o no). O, alternativamente, valores preseleccionados de R.
b) Un método alternativo almacena en la memoria del sensor los valores de SpO2 (mínimo) y SpO2 (máximo) del margen de spline, el número de nudos
que estarán definidos, y la secuencia de valores definidos de R para estos
nudos.
c) Otro método alternativo podría almacenar el SpO2 y el valor R asociado para
cada nudo.
Para cada una de estas opciones, el instrumento usaría un algoritmo de ajuste de
spline, preferiblemente un spline cúbico, para determinar el SpO2 en el valor de R medido según los valores almacenados (una alternativa podría ser un algoritmo de interpolación de orden superior o lineal). [0031] La Fig. 4 ilustra el método de spline cúbico. La Fig. 4 es un gráfico de saturación de oxígeno frente a R para un emisor de sensor concreto. Por lo tanto, en lugar de almacenar los coeficientes como en el método de la técnica precedente, los valores de la saturación de oxígeno y R reales se calculan y almacenan en la memoria del sensor para las características del sensor concreto (p.ej., longitudes de onda del emisor). Cuando el oxímetro mide el nivel de señal del detector de luz, éste determina un valor de saturación de oxígeno determinando el punto en la curva asociado al valor de R calculado entre dos de los puntos de muestra mostrados en la Fig. 4. [0032] Existe un equilibrio entre el número de nudos definidos y la cantidad de memoria requerida para almacenarlos. Muy pocos nudos requieren muy poca memoria de almacenamiento, pero pueden no describir de forma adecuada la relación funcional; demasiados definen en exceso la curva y consumen más memoria. Los inventores han descubierto que los nudos espaciados un 5%-10% dan resultados adecuados.
Cálculo de spline cúbico:
[0033] El proceso de interpolación de spline cúbico es conocido para aquellos con experiencia en la técnica. Intrínseco al uso del método de spline es que el valor de R necesita determinarse primero antes de ser trasladado a la SpO2. El proceso preferido
de interpolación de spline puede lograrse usando las funciones proporcionadas en Mathcad, y trata los puntos extremos con funciones cúbicas. Hay disponibles otras referencias para las interpolaciones de spline cúbico. [0034] El proceso de encontrar las coordenadas de los nudos en datos empíricos con una cantidad significativa de ruido puede exigir un paso adicional. Los programas de ajuste de curva básicos disponibles en el mercado pueden usarse (sigmaPlot, o TableCurve, o Mathematical por ejemplo) para determinar la aproximación funcional de mejor ajuste de los datos. Alternativamente, se puede llevar a cabo un ajuste de mínimos cuadrados de una función analítica seleccionada de forma arbitraria y escoger los valores de R en las localizaciones del nudo (valores de SaO2). La función
analítica puede ser un polinomio a trozos que solapan (p.ej., lineal o parabólico), o la ecuación curvilinea de Ec. 1 o Ec. 4. Otro enfoque es llevar a cabo una selección de mínimos cuadrados de los nudos directamente. [0035] La Figura 5A muestra el ajuste de curva convencional de la técnica precedente, en el que se usa una relación lineal por debajo del 70% de saturación, con un enfoque curvilíneo por encima del 70%. El error residual debido al ajuste imperfecto del R real para la respuesta de SaO2 del enfoque curvilíneo por encima del 70% de saturación
se ilustra mediante la curva 60, mientras que el error residual del enfoque de interpolación lineal por debajo del 70% se ilustra mediante los puntos 62. La Figura 5B ilustra el uso de ajustes curvilíneos en ambas regiones, usando una curva curvilínea diferente 64 por debajo del 70%. En este ejemplo, se proporciona un ajuste muy mejorado. En ambas figuras, la línea de puntos más pequeña 66 corresponde al uso de un solo ajuste curvilíneo a lo largo de ambas regiones, que tampoco resulta tan exacto, teniendo una característica de error muy superior en comparación con las curvas de la invención, 64 y 60 de la Figura 5B. [0036] La Figura 6A y 6B muestra una pluralidad de nudos como círculos 70 en los gráficos. La línea de puntos 72 de la Figura 6A ilustra un ajuste de interpolación lineal a estos nudos, que muestra un resultado propenso al error residual con múltiples curvas. En la Figura 6B, por otra parte, la presente invención que usa un método de ajuste de spline cúbico proporciona una línea de puntos 74 que presenta un ajuste más exacto a los nudos 70. [0037] Como entenderán aquellos con experiencia en la técnica, la presente invención puede ponerse en práctica en otros modos de realización específicos sin salir de las características esenciales de la misma. Por ejemplo, puede usarse cualquier función para las fórmulas para determinar la saturación de oxígeno, no solo las descritas. Para una memoria del sensor limitada, la representación de la función puede comprimirse. Puede utilizarse cualquier representación de una función. Los coeficientes de calibración pueden basarse en más o diferentes características además de la longitud
o longitudes de onda de los LED del sensor. Por ejemplo, otras características del emisor de LED o características del diseño del sensor pueden ser factores en los coeficientes de calibración del sensor. [0038] Además, la fórmula para calcular la saturación de oxígeno puede ser una función de más de la ratio de ratios; por ejemplo, podrían usarse otras variables de entrada como la fuerza de la señal, niveles de luz y señales de múltiples detectores. [0039] La descripción anterior pretende ser ilustrativa, pero no limitativa, del ámbito de la invención que se expone en las reivindicaciones siguientes.
