："pi Blood Perfusion Index, Perfusion Indicator
PI, as a parameter indicator, typically reflects the perfusion status of the limb being tested, indicating the machine's detection accuracy. It can still be detected under conditions of low and weak perfusion.
Moreover, the display of PI can also indicate the problems of the patient's own limb condition, that is, when low perfusion occurs, it indicates whether the patient has their own causes such as heart problems or shock, and it can also reflect whether there are external factors such as cold weather or poor peripheral circulation, thereby making judgments based on the above conditions!
PI refers to the perfusion index (Perfusion Index, PI), which reflects the pulsatile blood flow situation, that is, the blood flow perfusion ability. The larger the pulsatile blood flow, the more the pulsatile component, the larger the PI value. Therefore, the measurement site (skin, nail, bone, etc.) and the patient's own blood flow perfusion situation (the flow of arterial blood) will affect the PI value. Since the sympathetic nervous system affects heart rate and arterial blood pressure (affecting the pulse arterial blood flow), the human nervous regulation system or mental state will also indirectly affect the PI value. Therefore, the PI value will also be different under different anesthesia states.
