The Function of PI（Perfusion Index）
The perfusion index is a convenient way to tell you the intensity of your pulse. If the value is less than 0.2%, it means your hand is too cold or the position in the oximeter is incorrect. Just heat your finger and reposition your finger so that it is between the LED light and the sensor. There is no need to make a second guess to determine if the reading is reliable or why the pulse oximeter cannot give a reading.
