The Pulse Oximeter is a medical device which measures the level of oxygen in the arterial blood of the human body.Pulse Oximeter is widely used in hospitals around the world and plays a crucial role in health care system.Since their invention, the pulse oximeter has been revolutionized in many aspects of its hardware and software design.However, there are still some problems that limit their performance.Many researchers and scientists are currently working to improve the performance parameters of pulse oximeter.But due to lack of an accurate Computer Based Simulink Model, the only other way is hardware implementation which is very expensive.Changing the hardware design every time with a new idea is difficult and unrealistic.So, this project focus on designing a Computer Based Simulink Model for Pulse Oximeter with help of which new ideas can be implemented first on a software model before evaluating it on real hardware model.This Simulink Model can also be used in future as enhancement tool for further design and development of Pulse Oximeter.The main aim is to make a Simulink Model of a Pulse Oximeter which provides a modeling environment to implement new ideas and design before evaluating it on hardware model.The project focuses on designing a Simulink Model and its Graphic User Interface (GUI).It shows how different parts are modeled together and their simulation results.The Graphical User Interface will display different graphs depending upon number of oxygen molecules attached with hemoglobin molecule
