Abstract(es_ES)

La ventilación mecánica (VM) es una estrategia terapéutica que consiste en asistir o reemplazar mecánicamente la ventilación pulmonar espontánea. Con el objetivo de desarrollar un software de apoyo para los médicos, se realizó un estudio de las señales respiratorias, utilizando la transformada de wavelet discreta, para determinar los descriptores que indiquen si el paciente puede ser desconectado del ventilador mecánico. Para reducir la dimensionalidad del sistema se realizó un análisis de componentes principales (PCA), determinando tres variables óptimas, las cuales son las entradas a los clasificadores que se analizaron en el artículo: K-Nearest Neighbor y lógica difusa.

Keywords(es_ES)

Análisis de componentes principales; clasificador K-Nearest Neighbor; clasificador lógica difusa; transformada wavelet; ventilación mecánica

Abstract(en_US)

The mechanical ventilation (MV) is a therapeutic strategy to mechanically assist or replace spontaneous breathing. With the objective of developing a software support for doctors was performed a study of respiratory signals using the discrete wavelet transform to determine the descriptors to indicate whether the patient can be disconnected from the mechanical ventilator. To reduce the dimensionality of the system was performed a principal component analysis (PCA), establishing three variables optimal, which are the inputs to the classifiers that were analyzed in the article: K-Nearest Neighbor and fuzzy logic.

Keywords(en_US)

Fuzzy logic classifier; K-Nearest neighbor classifier; mechanical ventilation; principal component analysis; wavelet transform.
