1) Systolic Pressure: The tests were performed with subjects of varying age, height, and weight as listed in Table V. By obtaining the VTT and Ps for the five subjects as explained in Section III,we compared the estimated values of Ps from VTT with the pressure measured using a meter. Fig. 12 shows a plot of systolic pressure versus VTT. The meter-based readings are joined by a straight dark line in the center. The points labeled as “Data” refer to different individuals. The results obtained by applying(6)to all the individuals regardless of the age,height,or weight for Ps computation, yielded accuracies of above 95%. Based on these results, we can infer that factors such as age, height, and weight did not impact the end result of proposed system. We also observed that,for an increase of 10 ms of VTT, the systolic pressure dropped linearly by 4.25 mmHg. The method has not been tested with people having a history of cardiac disorders. The results and accuracy could also vary for people with ailments and disabilities due to changes in their vascular system.
