The most widely used monitoring tool to keep track of the perfusion index is the pulse oximeter. 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 … See more The perfusion index represents the ratio of the pulsatile blood flow to the non-pulsatile static blood flow in the peripheral tissues and limbs, such as toes, finger tips, and ear lobes. This might … See more The reason having a perfusion index on your pulse oximeter is a good idea is because it can help increase the accuracy of the readings which … See more Being familiar with the perfusion index is important, particularly if you are using a pulse oximeter to measure your blood oxygen levels.
