Stochastic Modeling and Dynamic Analysis of the Cardiovascular System with Rotary Left Ventricular Assist Devices

Figure 7

Hemodynamic waveforms in the presence of uncertainty in SVR. For the first and second column, the solid blue lines represent the mean value of each state variable in (5), while the red dotted line represents the -order gPC coefficients that can be used to calculate the standard deviation ( in the last column) at each time interval. The last column shows the mean, maximum, and minimum value of each state variable, i.e., left ventricular pressure, aortic pressure, aortic flow, and pump flow.
