Context: Blood Pressure (BP) measurement becomes a vital parameter now days due to the continuous increase in chronic heart diseases worldwide. Existing devices for BP measurement are less portable and also does not support continuous BP measurement. Many studies have been done on non-invasive BP measurement using electrocardiography (ECG) and photoplethysmograph (PPG) waveforms. These methods also clarify accurate results.Calculation of PTT and BP:This study relates BP measured using two PPGs with the existing methods which uses the ECG signals. The cuff and ECG signal can be replaced by PPG sensors as the results acquired using PPG signals gives high accuracy.Basic terms can be defined to relate BP followed by detection of P-base point and ends with the estimation for BP calculations.Proposed Methodology: The algorithm for the proposed technology can be defined and the work shows how the use of wavelet de-noised PPGs can replace the existing ECG based techniques to decrease the complexity of overall devices and also increases the precision level.Results and Discussion: Analysis of all the type of combinations can show the results that minimum error and maximum accuracy can be found when BP is estimated. Conclusion: PTT based on two PPG’s are best among all other methods including the utilization of second order non-linear regression technique.
