Design a noninvasive digital blood pressure meter using high sensitivity pressure gauge MPX5050GP

In this paper is discussed at the development of noninvasive, high precision, continues blood pressure measurement using factor calibration for eliminated signal conditioning. We developed a low cost noninvasive blood pressure (NIBP) measurement system using high sensitivity pressure gauge MPX5050GP which uses the behavior mercury sphygmomanometer. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) can be computed by using time difference between blood flow velocities in vein. From experiments result, MPX5050GP have possession of accuracy 0.01187 volts for each step 1 mmHg with relative error under 7%.
