globin (HbO
2
) in the total hemoglobin of the arterial blood. SpO
2
is an
important physiological parameter to reflect the respiration function; it is
calculated by the following method:
SpO
2
= HbO
2
/ (HbO
2
+Hb)×100%
HbO
2
are the oxyhemoglobins (oxygenized hemoglobin), Hb are those
hemoglobins which release oxygen.
