Pump speed modulation control input (Figure 2a), the actual pump speed achieved for this control input (Figure 2b), the left side pump flow (Figure 2c), the right side pump flow (Figure 2d), the resulting induced systemic arterial pressure waveforms (Figure 2e), and the resulting induced pulmonary artery pressure waveforms (Figure 2f) for the sinusoidal profile at three speed modulation amplitudes. All data displayed were collected at the same fixed pump and hemodynamic conditions designated as “Baseline” and defined as an average pump speed of 2,700 rpm, pump flow of 5.6 L/min, systemic vascular resistance of 1,200 dyne·sec·cm⁻⁵, and systemic compliance of 1.5 ml/mm Hg.
