Fingertip Pulse Oximeters
Heamoglobin Saturation Upper Level
This indicates the maximum percentage of hemoglobin molecules in the arterial blood which are saturated with oxygen
Hemoglobin Saturation Lower Level
This indicates the minimum percentage of hemoglobin molecules in the arterial blood which are saturated with oxygen.
The perfusion index (PI) is the relative assessment of pulse rate in the human body. PI index ranges from . 02% (very weak pulse strength) to 20% (very strong pulse strength).
It is an instrument for recording and measuring variation in the volume of a part of the body, especially as caused by changes in blood pressure.
