WebMay 1, 2024 · HM3 Pump Design. The HM3 is a fully magnetically levitated LVAD and has 4 unique features: (1) a fully magnetically levitated rotor, (2) large blood flow pathways, (3) intrinsic pulsatility, and (4) an intradevice operating system.10. The rotor is fully levitated and self-centered, without the need for hydrodynamic or mechanical bearings.

WebJan 17, 2024 · Ultrasonography is the modality of choice for imaging the urinary tract. 12 The association of conventional ultrasonography with Doppler mode allows for the evaluation and detection of hemodynamic changes that can affect renal function. 13,14 Resistivity index (RI) and pulsatility index (PI), calculated from the systolic and diastolic … WebSep 1, 2024 · Pulsatility is a combined measure of perfusion in the burn wound and how well the average heart-beat is propagated to the microcirculation. This measurement is different from previously used pulsatility measurements such as perfusion index. We hypothesized that pulsatility would be able to predict surgical need earlier than … WebMar 5, 2016 · Another way to quantify portal flow pulsatility is a simple ratio between the minimum and peak flow. 7 Using this approach, a flat waveform would have a portal vein pulsatility (PVP) of 1 and a very pulsatile waveform where the minimum velocity dropped to the baseline would have a PVP of 0.
