Calculation of a Pulsatility Index (PI) can then be used to substantiate a poor graft after assessment of a graft's mean flow and waveform profiles. A poor flow value

One of the disadvantages of indices derived from ultrasonic Doppler signals is that they are not normally available instantaneously. In an attempt to overcome this problem, a real-time spectrum analyser has been interfaced to an Intel 8085 microprocessor system and programmed to calculate pulsatility index in real time.

Median uterine artery pulsatility index multiples of the median (MoM) (with 95% CIs) derived from the model, according to racial origin, chronic hypertension, diabetes mellitus, method of conception and smoking in pregnancies that were unaffected by pre‐eclampsia (PE) (black values) and those that developed PE (red values). We defined a novel hemodynamic index, the pulmonary artery pulsatility index (PAPi), and explored whether the PAPi correlates with severe RVD in acute IWMI. Methods : From 2008 to 2010, we identified 20 patients presenting with angiographically confirmed proximal right coronary artery occlusion and suspected RVD (sRVD) as defined by hemodynamic instability, profound bradycardia, or ST Recently, a method for non-invasive ICP measurements was suggested: the Pulsatile Index (PI) calculated from transcranial Doppler data assessed from the middle cerebral artery. In this thesis the relation between PI and ICP was explored in INPH patients during … PaPi was calculated as [ (systolic pulmonary artery pressure-diastolic pulmonary artery pressure)/right atrial (RA) pressure]. Univariate analysis was performed to identify baseline predictors of RVF. Multivariate logistic regression was used to adjust for baseline RA pressure.

2020-01-02 · Pulmonary artery pulsatility index (PAPi) = (systolic pulmonary arterial pressure − diastolic pulmonary pressure)/right atrial pressure. This is the pulmonary arterial pulse pressure divided by the right atrial pressure (right ventricular filling pressure).

It is an index easy to calculate, less influenced by the correct angle of insonation, and is more accurate in expressing the combination of many factors affecting the cerebral blood flow. Results The predictability of uterine artery mean pulsatility index (PI) at 11–14 weeks for hypertensive disorders of pregnancy was significantly high with an odds ratio of 174.45 (95% CI 65.31–549.13; p < 0.0001), sensitivity (89.3%), specificity (95.8%), positive predictive value (90.5%) and negative predictive value (95.1%). the lesion and for calculation of Resistive index (RI) and Pulsatility index (PI) Doppler ultrasound was performed .Operative findings were recorded. Post operative histopathological findings were considered as gold standard for characterization of benign or malignant ovarian masses.

The calculated heart rate estimate agreed well with the noted value from the heart rate HR , pulsatility index PI and signal trends from adjustable time intervals.

In an attempt to overcome this problem, a real-time spectrum analyser has been interfaced to an Intel 8085 microprocessor system and programmed to calculate pulsatility index in real time. The only additional patient signal required is a simple three-lead e.c.g Correlation between intracranial pressure and pulsatility index measured by transcranial Doppler in children with severe trauma brain injury.
