- 6. Partial pressure of arterial blood oxygen refers to A: Oxygen partial pressure when oxygen saturation of hemoglobin is 50% B: Tension caused by oxygen molecules dissolved in arterial blood C: Hemoglobin and oxygen binding capacity D: The actual number of milliliters containing 02 in 100ml of blood E: Tension created by chemically bound oxygen in the blood
- Partial pressure of arterial blood oxygen refers to ( ) A: Tension caused by oxygen molecules dissolved in arterial blood B: Oxygen partial pressure when oxygen saturation of hemoglobin is 50% C: Hemoglobin and oxygen binding capacity D: The actual number of milliliters containing 02 in 100ml of blood E: Tension created by chemically bound oxygen in the blood
