Blood oxygen content

Oxygen content (oxygen content) refers to the oxygen content in the blood under the condition that the blood is isolated from the air, including two parts: physical dissolution and chemical combination, reflecting the actual oxygen content in the blood sample. 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.
