Abstract:
Many diseases, such as cardiovascular and dengue fever, require constant monitoring of certain health parameters of patients which sometimes, is disturbing to patients who requires plenty of rest. In this paper, we present a non-invasive technique based on wireless sensor networks to monitor the temperature, blood pressure and the pulse rate automatically without having to disturb a resting patient. The wireless sensor node captures these vital health parameters and then sends them to a smart phone via Bluetooth. The smart phone handles all the processing tasks and produces systolic and diastolic heart rates and gives alerts whenever an abnormal condition occurs. The prototype device managed to perform at 99.76 %, 88.40% and 92.70% accuracy levels on monitoring the temperature, blood pressure and pulse rate, respectively. The system, designed using low-cost peripherals with minimal electronic devices, can be used to monitor patients even from a remote location via wireless technology.
