a) Perfusion index (PI): PI is a value that indicates arterial pulse signal strength as the
percentage of pulsatile signal to non-pulsatile signal. The perfusion index allows
clinicians to place sensors on optimal sites.
b) Methemoglobin Saturation (SpMet): SpMet is a value that represents the
percentage of methemoglobin saturation within the blood.
c) Total Hemoglobin (SpHb): SpHb is a measure of the total hemoglobin
concentration in arterial blood.
d) Oxygen Content (SpOC): SpOC is a measure of the total oxygen content present in
e) Carboxyhemoglobin Saturation (SpCO): SpCO is a value that represents the
percentage of carboxyhemoglobin saturation within the blood.
f) Pleth Variability Index (PVI): PVI is a measure of peripheral perfusion changes
secondary to respiration, or the PI amplitude modulation over a respiration, and can be
closely related to intrathoracic pressure changes.
