Advances in Hemodynamic Analysis in Cardiovascular Diseases Investigation of Energetic Characteristics of Adult and Pediatric Sputnik Left Ventricular Assist Devices during Mock Circulation Support

Figure 7

(a) Average levels of left ventricle work, PRBP work, and total work for simulated state of acute heart failure in 2-year-old pediatric patient with mass of 15.2 kg in the pump speed range of 6000–13000 rpm with 200 rpm step. Levels of left ventricle work in normal and heart failure states are also represented for comparison. (b) Average aortic valve and pump flow rates with respect to normal state, heart failure, and states in the pump speed range specified.
