Abstract

Uno o más aspectos de la descripción se refieren a la vigilancia de la frecuencia respiratoria y de la frecuencia cardíaca de un sujeto en reposo por medio de un radar de banda ultra ancha por radio de impulso (IR-UWB) de manera no invasiva, con el fin de inferir el estado de salud correspondiente, incluyendo la frecuencia cardíaca y la frecuencia respiratoria. Se puede utilizar cualquier otra tecnología de reflectancia. Estos dos signos vitales cardiopulmonares se derivan sobre la base del procesamiento de formas de onda registradas que son recogidas por el radar IR-UWB o cualquier otro sistema de tecnología de reflectancia, después de obtenerlos reflejados del cuerpo del sujeto en reposo o en la parte relevante del cuerpo. Se propone un algoritmo novedoso que procesa las formas de onda grabadas para extraer estas señales de estos signos vitales y, en consecuencia, estimar sus frecuencias. Este algoritmo incluye al menos tres etapas principales: i) reducción de ruido, ii) estimación de la frecuencia respiratoria y iii) estimación de la frecuencia cardíaca. Además, el algoritmo aborda os efectos de los armónicos y la intermodulación entre las señales de respiración y latidos del corazón sin necesidad de la implementación de filtros.
