In this paper, the AUTOMIXER, a medical support equipment for the reduction of risks associated with the inadequate supply of oxygen, is presented. The equipment automatically regulates the Inspired Oxygen Fraction (FIO2 concentration), which is supplied to the patient according to user parameters, measures of oxygen saturation and patient's status. The AUTOMIXER is based on a fuzzy control system, which was implemented in a microcontroller using a LookUp Table. The operation of the device was validated using simulated data and actual patients. The results show that the AUTOMIXER is an important tool for decreasing the incidence of pathologies related to unsuitable handling (excess or lack) of oxygen.
En este trabajo se presenta un equipo de apoyo médico, para disminuir el riesgo por suministro inadecuado de oxígeno; denominado AUTOMIXER. El equipo desarrollado regula de manera automática y precisa la Fracción Inspirada de Oxígeno (concentraciónFiO2), que se le suministra al paciente de acuerdo a los parámetros programados por el usuario, las medidas de la saturación de oxígeno y el estado del paciente. El AUTOMIXER está basado en un sistema de control difuso, el cual fue implementado en un micro controlador usando una LookUp Table. Para validar el funcionamiento del dispositivo, se realizaron diferentes pruebas con datos simulados y con pacientes reales; los resultados muestran que el AUTOMIXER se vislumbra como una importante herramienta para disminuir la incidencia de las patologías, asociadas al manejo inadecuado (exceso o falta) del oxígeno.
