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.

Also, high values of shear rate and Reynolds stresses were simulation to the study of pulsatile flow in a modeled arterial stenosis.

Mean venous pulsatility index for normal outflow veins was 0.75, and mean venous pulsatility index in stenosed veins was 0.39. A venous pulsatility index of < 0.45 was 95.7% specific for stenosis. The areas under the receiver operating characteristic curve were 0.83 for peak anastomotic velocity, 0.86 for anastomotic-to-preanastomotic velocity ratio, and 0.84 for venous pulsatility index

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. 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.

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 perfusion index is calculated by dividing the pulsatile signal (AC) by the non-pulsatile signal (DC), multiplied by 100. This is then expressed as a percentage which ranges from 0.02% to 20%. The perfusion index can also be an indication of how reliable the reading from the pulse oximeter is.
