Introduction
PO2 refers to the partial pressure of oxygen in the blood. The partial pressure of oxygen in blood generally indicates the tension exerted by oxygen molecules in the bloodstream, and normal values differ between venous and arterial blood. Typically, the normal venous blood PO2 ranges from 37 mmHg to 40 mmHg, while the normal arterial blood PO2 usually ranges from 80 mmHg to 110 mmHg.

Blood oxygen partial pressure generally refers to the tension exerted by oxygen molecules in the blood, and normal values differ between venous and arterial blood. Normally, venous blood oxygen partial pressure ranges from 37 mmHg to 40 mmHg, whereas arterial blood oxygen partial pressure is typically between 80 mmHg and 110 mmHg. To determine one's own blood oxygen partial pressure, a blood gas analysis can be performed at a hospital, which helps clarify the exact value. It is advisable not to take medications blindly before undergoing such tests, as this may easily affect the blood's acid-base balance and lead to inaccurate results. Therefore, it is recommended to consult a physician actively and make appropriate preparations before testing to avoid misdiagnosis.
Based on specific blood oxygen partial pressure values, it is possible to determine whether hypoxia or oxygen toxicity exists. If test results show abnormal blood oxygen partial pressure, a comprehensive physical examination should be conducted according to medical advice to fully understand one's condition, and treatment should be followed as directed by a physician when necessary.
