Vital sign monitor with emergency control

Negligence of the health care representatives during emergency situations causes numerous deaths in the hospitals. Developing an efficient, quick and reliable health care monitor with emergency control can help reduce human errors. This project is based on monitoring patients admitted in hospitals. It is a health monitoring device which measures the heart rate, blood pressure and body temperature of patients. After the vitals are measured accurately, it transmits them wirelessly to a monitoring room using ZigBee. In emergency situations, abnormal vitals are sent to the doctor and the emergency contact using a GSM module. There are many monitoring systems using Bluetooth, but monitoring using ZigBee has many advantages. There is a new approach by adding a GSM module, as the vitals can be received on any telephone as a SMS. This is very useful when they need to be sent to an emergency contact or the doctor in charge. This elementary, cost efficient health monitoring system is based on a simple controller. The main result achieved by this approach is the reduction of the micro controller processing time by twelve, due to which the end to end execution time of the system is also reduced. The heart rate of the patient is also measured with medically approved equipment unlike the previous models
