LVAD Patient Care At the Local Level Laura Blue, MSN, NP . Laura Blue is a consultant for Thoratec Corporation Pulsatility Index (PI): 2-6 .

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. The pulmonary artery pulsatility index (PAPi), defined as [ (systolic pulmonary artery pressure – diastolic pulmonary artery pressure)/CVP], is a hemodynamic index originally used to predict RVF in inferior wall acute myocardial infarctions. Recently, PAPi has also been shown to be an independent predictor of postoperative RVF in continuous-flow Pulmonary Artery Pulsatility Index Early Post-LVAD Implantation Predicts Severe Right Ventricular Failure April 2019 The Journal of Heart and Lung Transplantation 38(4):S358 Reading Time: 2 minutes Some parameters on an LVAD are simple and easy to understand, but the pulsatility index can be more challenging. Dr. McCloskey breaks it down for us in this post.

Notwithstanding, cerebral auto- Low cardiac index is. of the Left Ventricular Assist Device or before caring for HeartMate 3 patients. LVAS employs a feature called Pulsatility Index (PI) Detection to recognize and LVAD Patient Care At the Local Level. Laura Blue, MSN, NP HeartMate II LVAD: A Continuous Flow Pump 8,000-10,000 rpms. ▫.

• The Pulsatility Index (PI) is a measurement of the flow pulse through the pump (coming from the heart) • During LV filling, increase in pressure causes an increase in pump flow (higher PI indicates better LV function) • PI should be monitored routinely – A significant drop … Pulmonary Artery Pulsatility Index Is Associated With Right Ventricular Failure After Left Ventricular Assist Device Surgery. PAPi is a simple hemodynamic variable that may help to identify patients at high risk of developing RVF after LVAD implantation. The pulmonary artery pulsatility index (PAPi) is a novel hemodynamic index that predicts RVF in the setting of myocardial infarction, although it has not been shown to predict RVF after LVAD implantation.

Pulsatility Index (PI): 1 – 10; How often does life threatening VAD malfunction occur? [1] 1st generation VADs: 6% at 6 months and 64% at 2 years; 2nd generation VADs: 54% at 2 years for continuous flow LVAD [cite source=”pubmed”]19920051[/cite] What are some of the common VAD malfunctions, how should they be evaluated, and treated?[1] 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. Background Right ventricular failure (RVF) is a major cause of morbidity and mortality after CF-LVAD implantation.
