نبذة مختصرة : The work presented in this article is framed in the field of medical simulator development based on models. The purpose of this work is to accelerate interdisciplinary research and enhance the skills, dexterity, and expertise of healthcare professionals without invasive practices on the patient. To this end, we propose an educational simulator of neonatal cardiovascular physiology, implemented in Modelica based on the analogy with a hydraulic model. This tool allows for the simulation of the normal state of a newborn, cardiac pathologies such as coarctation of the aorta and transposition of the great arteries. It also enables visualization of physiological variables like pressure, volume, blood flow, elastance, vascular resistance, and relationships such as ventricular pressure-volume to assess the cardiac cycle. This work is a first step in the development of simulators of complete neonatal physiology that allow evaluating the patient's evolution with the application of a treatment. The development of these tools facilitates the reduction of human error and allows for testing without consequences for patients. Keywords: Simulation, Neonate, Cardiovascular Physiology, Cardiac Pathology, Teaching in Medicine and Biomedicine.
