In this project we present the Accessible GSM Based Embedded Medical Critical Care Signal Monitoring System. This device has been designed to be accessible for clients of different abilities and ages. The Accessible GSM based Medical Critical Care Signal Monitoring System that we have designed measures blood pressure, blood oxygen saturation, heart rate, temperature and respiration rate using non invasive technique and takes step wise measures in extreme conditions. In this system, these vital signs are displayed on a monitor and sent to a computer via Bluetooth as well as send these data to patents relatives mobile number as well as cross ponding Doctors, Nurses mobile number for immediate assistance via GSM based SMS technique and through a secure website that is part of the system, the patents and their relatives can upload their vital signs via any Internet connected computer. This allows clients to communicate their health status to physicians and healthcare providers anywhere in the world. Accessibility is provided through a large, well lit LCD screen, a speaker Alarm system, and Braille customized buttons. Vital signs are displayed on the large LCD screen, as well as alarmed through a speaker system in extreme situations. A simple 3 button design provides an easy to use user interface, appropriate for all age levels and technological savvy. Also, all buttons are customized with Braille or Universal Symbols for the vision impaired. The monitor includes solar rechargeable back up batteries in case of power failure, or if the client just does not to be homebound by their health monitoring needs. The implementation of the project includes various hardware components as well as software.
