Analysing the Performance of Blood Pressure Parameters Using EMF Method
2020
The measurement of Blood pressure for years has been done by the auscultatory method, where a trained person inflates a cuff around the patient and identifies the highest and lowest values of pressure during the cardiac cycle and there is a growing need to create awareness and have the right means to calculate blood pressure. The idea is based on the principle of magnetic blood flow meter and when the arm placed inside the region of the magnetic field there is an EMF produced due to the flow of blood in the artery. The output of this stage is fed into the signal conditioning circuit and the final systolic and diastolic blood pressure values are obtained with maximal accuracy. The results were analyzed with the traditional sphygmomanometer and the digital sphygmomanometer which indicates that when miniaturized into compact models the device can measure blood pressure continuously and non-invasively and is capable of replacing the current cuff method as the accuracy of the device is maintained and errors were also in the tolerance range with minimal contact with the patient's skin.
