7. SpHb (Total Hemoglobin) value and unit;
8. SpOC (Oxygen Content) value and unit;
9. SpMet (Methemoglobin Saturation) value and unit;
10. PVI (Pleth Variability Index) value and unit.
Note: When one of the above parameters’ signals is weak, its label
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
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.
