C(a-v)O2 difference: CaO2 = 18, CvO2 = 14.

The difference in oxygen content between arterial and venous blood shows how much oxygen is extracted by body tissues in one pass. It’s found by subtracting CvO2 from CaO2: CaO2 − CvO2. Here, 18 minus 14 equals 4. So the C(a-v)O2 difference is 4 ml O2 per 100 ml of blood. This reflects the amount of oxygen that tissues remove from the blood as it travels through the capillaries.
