Do you know what your temperature should be? Find out what’s too high, too low, and (pretty much) just right. Your body’s like a little furnace. It puts out heat all the time. It comes from your body doing the work that keeps you alive. Whe

Therefore, the main study objective was to derive normative new day-cycle-based reference ranges for the UtA-PI during the entire cycle from days 1 to 34 according to the isolated time effect and potential confounders such as age and parity. 2021-04-10 · OBJECTIVES: To calculate the normal range for the fetal middle cerebral artery (MCA)/uterine artery pulsatility index (PI) ratio in the third trimester of pregnancy and to assess its value, compared with that of the MCA/umbilical artery PI ratio, in predicting an unfavorable outcome of pregnancies complicated by pre-eclampsia. PI’s values range from 0.02% for very weak pulse to 20% for extremely strong pulse. The perfusion index varies depending on patients, physiological conditions, and monitoring sites.

Patients were divided by low (<5.5) and normal PAPi (≥5.5) for further evaluation of hemodynamics and RV remodeling.

The sensitivity and specificity of these indexes in the detection of acute rejection varies depending on the cut-off levels used and ranges from 43% to 82% and from 33% to 100%, respectively (6,12–14).

The pulmonary artery pulsatility index (PaPi) is a recently described hemodynamic metric. We evaluated baseline PaPi as a predictor of post-operative right ventricular failure (RVF) following LVAD surgery.

The pulmonary artery pulsatility index (PaPi) is a recently described hemodynamic metric. We evaluated baseline PaPi as a predictor of post-operative right ventricular failure (RVF) following LVAD surgery. Methods: We conducted a retrospective review of 132 consecutive LVAD implantations at our hospital.

The perfusion index varies depending on patients, physiological conditions, and monitoring sites. Be-cause of this variability, each patient should establish his own “normal” perfusion index for a given location and use this for monitoring purposes. Chen M, Chen H, Yang X, et al.

Background. The pulmonary artery pulsatility index (PAPi), defined as the ratio of pulmonary artery pulse pressure to right atrial pressure, emerged as a powerful predictor of right ventricular (RV) failure in patients with acute inferior myocardial infarction and those undergoing left ventricular assist device placement; however, its prognostic utility in the advanced heart failure population

The MCA PI decreased as gestational age advanced from 1.97 (SD 0.48) at 20 weeks to 1.15 (SD 0.18) at We hypothesize that the uterine artery (UtA) impedance, measured by its pulsatility index (PI), exhibits a regular pattern during the normal menstrual cycle. Therefore, the main study objective was to derive normative new day-cycle-based reference ranges for the UtA-PI during the entire cycle from days 1 to 34 according to the isolated time However, few published normal ranges exist for all commonly measured fetal arterial and venous Doppler resistance and velocity parameters.Different multiple indices exist for assessing both resistance and velocity in fetal vessels. These include S/D and A/B ratios, resistance index (RI) and pulsatility index (PI).
