Design and Implementation of Vital Signs Simulator for Patient Monitor

Abstract

This study focuses on the design and implementation of vital signs simulator for patient monitors. A patient monitor has three major monitoring systems, including pulse oximeter, electrocardiogram (ECG) and Non-Invasive Blood Pressure Monitor. Medical equipment should be calibrated on a frequency basis, but simulations of vital signs are some of the ways to calibrate the reading of a patient monitor. The study included a prototype that can simulate the oxygen saturation and pulse rate for pulse oximeter, ECG pulse rate and waveform (normal and arrhythmias) and systolic and diastolic pressure and pulse rate for Non-Invasive Blood pressure monitor. Arduino microcontroller served as the main processing unit of the simulator of vital signs.
