Answer:
Saturation
Step-by-step explanation:
Blood oxygen saturation is usually used to detect respiratory insufficiency, this saturation increases according to a hemoglobin dissociation curve.
The curve analysis shows that hemoglobin saturation is linked to partial oxygen pressure (pO₂). The higher the pO₂, the higher the oxygen saturation in the blood. The average saturation in a healthy human being is between 95% and 99%.
