A Rigel patient simulator is used to reproduce vital signs and various clinical scenarios in a controlled and precise manner. This equipment is crucial for training medical personnel, testing and calibrating diagnostic equipment, as well as assessing emergency response skills. Patient simulators cover a wide range of functions, including simulation of cardiac activity (ECG), respiration, invasive and non-invasive blood pressure (NiBP, IBP), oxygen saturation (SpO2), body temperature and others. Whether used in training centers, hospitals or research laboratories, these devices provide an effective way to prepare medical professionals for the real challenges of clinical practice.
