Abstract

Se describen aparatos para determinar con precisión una concentración de gas de una muestra de la respiración de un paciente; los aparatos pueden incluir un compartimiento de muestra, un analizador de velocidad de respiración, un analizador de gas y un procesador; el compartimiento de muestra incluye una entrada que recibe la respiración; el analizador de velocidad de respiración determina la velocidad de una parte de la respiración; el analizador de gas determina una concentración de gas; el procesador incluye un algoritmo que determina un grado de no-homogeneidad de la muestra con base en la velocidad, y una concentración de gas corregida con base en el grado de no homogeneidad; en algunas variaciones, la corrección de gas es determinada independientemente de la cooperación del paciente; los aparatos pueden ser sintonizados con base en los rangos esperados del patrón de respiración de la población pretendida de manera que el compartimiento de muestra se llena con una muestra de gas del final de la espiración homogéneo sin considerar un patrón de respiración individual; estos aparatos son útiles, por ejemplo, para análisis de CO del final de la respiración; también se describen métodos.
