Gaussian Modelling Characteristics of Peripheral Arterial Pulse: Difference between Measurements from the Three Trimesters of Healthy Pregnancy

Figure 1

Demonstration of Gaussian modelling characteristics derived from orginal radial pulse waveform. (a) A segment of the original arterial pulse waveform measured by the pressure sensor; (b) Gaussian modelling of a radial pulse waveform. The radial pulse waveform was decomposed into three positive Gaussian waves as shown in red, blue, and green. The yellow curve shows the Gaussian fitted radial waveform.
