Other uses of the perfusion index can be found throughout various literature. Lacking the spike would indicate the lack of anesthetic effect. If the sensor and connector are OK, replacing the O2 Sensor 1 usually takes care of the problem. Before replacing the sensor, check for the condition of the heated oxygen sensor fuse and connectors. Studies have shown that an increase in PI is an early indicator that general or epidural anesthesia has initiated peripheral blood vessel dilation, which typically occurs before the onset of anesthesia. Water getting inside the heated oxygen sensor connector can cause the heated oxygen sensor fuse to blow. That day I was in rush for my office and at a speed of about 110 I had applied. Perfusion index is also used as an early warning of anesthetic failure. The sensors (4 in total) fail frequently. It is superior to qualitative approach such as foot warmth. Usually the heater wires on the sensorвЂ™s harness are both either black or white.

Now connect a female spade connector to each heater wire of the harness. Using the old harness will help eliminate the possibility of tapping into the wrong circuit, a potentially costly mistake. In neonatal acute care, a low PI is an objective and accurate measure of acute illness. When you replace a bad O 2 sensor, cut the sensor off the old harness. Studies have shown that PI has a high correlation with capillary refill time and central-to-toe temperature difference. In a hospital, perfusion index, along with many other parameters, is used to monitor critically ill patients. The pleth (Plethysmograph), available in many pulse oximeters, is a graphical representation of the perfusion index.

A perfusion index adds a lot of sensitivity to the oximeter sensor thus adding to the cost of the oximeter. Most people that use an oximeter at home would not need a perfusion index indicator because they are considered to be in general good health. Quick CPU is a program that was designed to fine-tune and monitor important CPU and System parameters such as CPU Temperature (Package and Core Temp), CPU Performance, Power, Voltage, Current, Core Parking, Frequency Scaling, System Memory, Turbo Boost, C-States, Speed Shift FIVR Control as well. There are oximeters, such as those from Masimo, designed for extreme low PI. For most pulse oximeters for general use, the reading is unreliable or unavailable if PI is at or below 0.4%. PI is also a good indicator of the reliability of the pulse oximeter reading. Perfusion index is normally monitored with pulse oximeters.
