Pulse rate
PR indicates the Heart Rate per minute which SpO2 module extracts from the pulse oximetry
signal.
Perfusion Index
Perfusion index (PI) indicates arterial pulse signal strength as a ratio of pulsatile blood flow to
the non-pulsatile blood.
Perfusion Index enables you to choose the best position for sensor placement
.
PI =
x 100%
PI definition
PI greater than 1% is preferable.
SpHb
SpHb indicates the level of total hemoglobin in the arterial blood. The unit of measurement is
grams per decilitre (g/dL).
SpOC
SpOC indicates oxygen content in the blood. Neither SpO2 nor Hb parameter by itself can
indicate the actual amount of oxygen in the blood. A patient with normal SpO2 or Hb may have
low levels of oxygen. In fact, both SpO2 and Hb are considered by SpOC parameter. The unit of
