What Is Pulsatility Index - Web tcd pulsatility index can be easily and quickly assessed but is usually misinterpreted as a descriptor of cvr. The formula is as follows: ( qmax − qmin )/mgf. [pi = (psv − edv)/mvf]. Pulsatility index is dependent on multiple variables including cerebrovascular resistance (cvr). The pi is proportional to the distance between maximum and minimum flow and inversely proportional to the mgf. Web the pulsatility index (pi) is a dimensionless parameter and is derived from a mathematical formula in which instant flows (qmax and qmin) are related to the mgf. Web pulsatility index (pi) is calculated by subtracting the peak systolic velocity (psv) from the end diastolic flow velocity (edv) and dividing the difference by the mean flow velocity (mvf); The mathematical model presents a complex relationship between pi and multiple haemodynamic variables.
