Pulsatility may result from blood ejected through the aortic valve or transmission of the systolic pressure wave through the LVAD (in cases of a closed aortic valve). The HeartMate II and HVAD both identify changes in power (and corresponding ﬂow) during systole and diastole using either a pulsatility index or a ﬂow waveform.

2019-05-18 CF-LVAD flow rate was measured with a Transonic ME13PXN flow probe at the outlet of the pump, connected to a Transonic 410 flow meter (Transonic, Ithaca, NY). The pulsatility was quantified using the index of pulsatility (I p) considering the fact that aortic valve remained Pump Speed How fast the LVAD pump is spinning to circulate blood through your body; it is measured in revolutions per minute (RPM). Flow Rate The amount of blood the LVAD is circulating through your body; it is measured in liters per minute (LPM). Pulsatility Index (PI) The PI value is related to the amount of assistance provided by the blood pump PA Pulsatility Index (PASP-PADP) / RA <1.85 (RVF after LVAD) [42] <1.0 (RVF in Acute MI)[41] Pulmonary Vascular Resistance mPA-PCWP / CO >3.6 (RVF after LVAD) [16] Trans-pulmonary Gradient mPA-PCWP Undetermined [36] Diastolic Pulmonary Gradient PAD - PCWP Undetermined[36, 37] RV Stroke Work (mPAP-RA) x SV x 0.0136 <15 (RVF after LVAD)[16] 2018-02-07 the arterial line is again visualized, an SpO2 is able to now read 99%, and the LVAD pulsatility index increases to 4.0. At this point in the procedure, the endoscopist notes she is unable to localize the bleeding source, and will have to perform a double balloon enteroscopy. LVAD will lose power and stop working.

The Thoratec HeartMate II (HM II) LVAS is the most commonly used LVAD worldwide. The user sets the RPM and the monitor provides online data on RPM, power consumption, flow, and pulsatility. These parameters are routinely used by clinicians to assess native heart function and to optimize pump settings.

Right ventricular failure (RVF) is a major cause of morbidity and mortality after left ventricular assist device (LVAD) implantation. However, AVO frequency was independent of opening area and systolic duration, which both decreased with increasing LVAD support. Furthermore, aortic pulsatility index quadrupled in the aortic root and doubled in the distal aorta during PLSA conditions, providing evidence that AVO and blood mixing are enabled by PLSA control at the appropriate 2019-10-10 Background Right ventricular failure (RVF) is a major cause of morbidity and mortality after CF-LVAD implantation. We explored the association of pulmonary artery compliance (PAC), pulmonary artery elastance (PAE), and pulmonary artery pulsatility index (PAPi) in addition to established parameters as preoperative determinants of postoperative RVF after CF-LVAD surgery.

From both a physiological and clinical standpoint, pulsatility is quantified by metrics such as pulse pressure (pulse pressure=systolic pressure−diastolic pressure) and the pulsatility index (pulsatility index=V max −V min /V mean), where V max, V min, and V mean are the maximal, minimal, and average blood flow velocities, respectively, in an arterial bed.

Technical care of the LVAD The LVAD requires regular care and system checks, including power-source changes, daily self-tests, and driveline dressing changes. Per - forming these tasks The LVAD has two basic designs which produce different patterns of perfusion, including the pulsatile and continuous-ﬂow devices.

Pulmonary artery pulsatility index (PAPi) is a haemodynamic parameter that is derived from right atrial and pulmonary artery pulse pressures. A number of reports have described the prognostic value of PAPi in patients with advanced heart failure and cardiogenic shock.
