ABSTRACT 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.
