Design and construction of a real simulator for calibrating lung servo-ventilators

This work shows the theoretical and practical development of a lung simulator for the calibration of Servo-ventilators of common use in health centers. It shows the development of a prototype device, Shown in the paper the formulation of a model to consider factors that exist in a human respiratory system in order to simulate normal and pathological conditions. Includes the calculation and construction of electronical and fluidic systems that were developed to set up an emulator that allows real lung adequate to connect with any type of servo-ventilator; as well as the results in terms of graphics of the required functions, highlighting the practical part that behaves like a real lung subsequently introduced into a torso anthropomorphic designed to better emulate real operating conditions of the lung embedded in a actual context closest to where the components behave as does the lung of a patient.
