According to Statistics, every year, about 610,000 people die because of heart disease in United States of America. (i.e. 1 in every 4 deaths.*) Heart disease is common for both men and women. Annually, about 370,000 people die because of coronary heart disease, which is the most common type of heart disease [1]. About 735,000 Americans have heart attack every year. In this, 210,000 people gets heart attack who already has heart problems and 525,000 people get heart attack for the first time [2]. Not many people know that they have heart problems. Around 47% of the people in United States of America have sudden cardiac arrests outside the hospitals [3].

To reduce the probability of death and to analyze the data of the body condition for the betterment of life, A wireless health monitoring system can be introduced. This health monitoring system is required for all ages of the people. In this fast moving busy world, wearable wireless health monitoring system is the most important system, which can continuously monitor the health of the patients/people. In this thesis, a wireless health monitoring system (A smart watch approach) can be developed which includes pulse and oxygen saturation.

The health monitoring system is designed with the wearable (smart watch) approach, through which the above parameters are monitored that shows the variation from which the disease can be detected and diagnosed initially. For this, the sensor modules are implanted in the daily wearable like watch that can monitor the body condition in real time and can send the data to the computer via Bluetooth and to the medical centers via Global System for Mobile (GSM) Long-Term Evolution (LTE) where the doctors can monitor their patients and act when they are in an emergency.

Here, the proposed prototype is implemented in the watch by which the data are collected from the wrist. In the engineering point of view, this watch that consists of pulse sensor will help in monitoring the patient’s body condition. The reflectance pulse sensor module consists of the IR led, the RED led and the photodiode. The sensor that takes up the PPG signal, process and sends it via Bluetooth to a receiver station with the help of an application and shows up the data on the screen. These signals can also sent to the medical centers using Wi-Fi and Cellular networks with LTE, through which the doctors can analyze the body condition of the patients.

With this engineering technology (both hardware and software), the health monitoring has been made easy and initiates the decrease in number of death caused by the cardiac arrest.
