What Is Oxygen Concentration?
Oxygen content refers to the content of oxygen in the blood under the condition that the blood is isolated from the air. It includes two parts: physical dissolution and chemical combination, reflecting the actual oxygen content in the blood sample.

- Oxygen content refers to the content of oxygen in the blood under the condition that the blood is isolated from the air. It includes two parts: physical dissolution and chemical combination, reflecting the actual oxygen content in the blood sample.
- It refers to the actual total amount of protein-bound oxygen and dissolved oxygen in plasma in 100ml of blood.
- The amount of oxygen dissolved is affected by PO2, and the oxygen partial pressure of 0.13kPa can dissolve 0.03ml / L of oxygen. Under normal circumstances, the dissolved oxygen is only 3ml / L, and the amount is very small. The actual measured oxygen content is the hemoglobin-bound oxygen. The blood oxygen content is determined by the hemoglobin content and the degree of binding between them.
