Pulsatility indices was calculated for each of these vessels. A new placental pulsatility index was constructed as: (umbilical artery pulsatility index + mean of the left and right uterine artery pulsatility indices)/2, and mean +2 SD defined as abnormal. Pulsatility Index > 50% may indicate marked venous congestion (thin patients may exhibit pulsatility in health). Figure 3 - RAAS activation in the physiology of Hyponatremia and AKI. RAAS stimulates proximal tubule sodium retention, loss of free water clearance, and reduced renal blood.

Design Serial 2D transvaginal coloured power doppler ultrasound performed in women on ART cycle to evaluate a pattern that better predicts implantation rates. One hundred sixty-nine subjects on a

Corrected Na; Heparin Rate Calculator; Pulmonary artery pulsatility index predicts right ventricular failure after left ventricular assist device implantation 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 aim was to compare pulsatility index (PI) values recorded by the MediStim and Transonic flowmeters in two different clinical settings: (1) analysis of the flow patterns recorded simultaneously by both flowmeters in the same CABGs; and (2) evaluation of flow patterns under different levels of filter settings in the same grafts.

Behrens, Anders; Lenfeldt, Niklas; Ambarki, Khalid; et al. 2010.

The fetal middle cerebral artery (MCA) pulsatility index (PI) is a key parameter used in fetal middle cerebral arterial Doppler assessment.. It is calculated by subtracting the end-diastolic velocity (EDV) from the peak systolic velocity (PSV) and then dividing by the time-averaged (mean) velocity (TAV):.

CONCLUSIONS: The pulsatility index is a better noninvasive technique than the ankle-brachial Doppler index or the systolic ankle pressure to assess critical limb ischaemia in diabetic polyneuropathy. A pulsatility index < 1.2 at the ankle arteries is a reliable criterion for diagnosis of CLI in diabetic patients with polyneuropathy.

A number of reports have described the prognostic value of PAPi in patients with advanced heart failure and cardiogenic shock. Mari G, Deter RL. Middle cerebral artery velocity waveforms in normal and small for gestational age fetuses. Am J Obstet Gynecol 1992;166:1262-1270. The study was designed to see if the pulsatility index (PI) measured by transcranial Doppler ultrasonography (TCD) predicts information about ICP values.
