ClinConnect Summary

The perfusion index is the ratio of pulsatile blood flow to non-pulsatile in peripheral tissues and can be measured non-invasively using a pulse oximeter .Perfusion index measurement is considered a non-invasive rapid indicator of microcirculation variation and can help to detect circulation disturbance.It also can assess peripheral perfusion dynamics resulting from changes in peripheral vascular tone. Perfusion index changes according to posture with its highest value in Trendelenburg position and lowest value during 45-degree sitting position. However, to the best of our knowledge, no stu...
