Continues Blood Pressure Measurement and Data Logging Device with SMS Alert

This paper presents a new blood pressure (BPs) measurement and data logging device which can be extensively used for ICU patients who are intended for a period of observation. The main purpose of this paper is to know about the changes in BP with respect to time and changes in the food taken by patient who are under observation. If any abnormal changes occur in the BP then the system alerts using a buzzer and it also sends a message to a predefined number (i.e., a physician number) using GSM. If not for each and every second it saves the data into SDcard in a file format, therefore appropriate steps can be taken in accordance with the changes in BP. The paper also took care of layman towards BP inorder to understand everyone even without the help of physician. This paper follows a Non-invasive type of BP measuring technique i.e., volume oscillometric method. Through the developed algorithm the BP measured is more accurate which is compared to the readings measured by sphygmomanometer. This system could be made with the features like cost effective, less complex, more reliable and easy to access.
