Real time Human Health Monitoring and Alert System for Cardiac Patients Using GSM and GPS

Nowaday‟s technology is running with time. we can not only increase the comfort of life but also increase the health monitoring techniques by making use of advanced technology. In this paper we are making use of technology to sense serious health problems so that efficient medical services can be provided to the patient in appropriate time. This paper is based on embedded system. The heart rate can be measured by monitoring one's pulse using specialized medical devices such as an electrocardiograph (ECG), portable device e.g. wrist strap watch, or any other commercial heart rate monitors which normally consisting of a chest strap with electrodes. For a patient whom already diagnosed with fatal heart disease, their heart rate condition has to be monitored continuously. This paper proposed an alert system that able to monitor the heart beat rate condition of patient. The heart beat rate is detected using photoplethysmograph (PPG) technique. This signal is processed using PIC16F87 microcontroller to determine the heart beat rate per minute. Then, it sends sms alert to the mobile phone of medical experts or patient‟s family members, or their relatives via SMS. Here we can get the alerting message from the GSM modem and the location of the person can be found with the help of GPS. Thus, doctors can monitor and diagnose the patient‟s condition continuously and could suggest earlier precaution for the patients themselves. This will also alert the family members to quickly attend the patient.
