When oxygen consumption decreases, there is less demand for oxygen and therefore less oxygen is extracted from the blood by the tissues. This results in an increase in the arterial oxygen content (CaO2) and a decrease in the venous oxygen content (CvO2). The difference between CaO2 and CvO2, known as the arteriovenous oxygen content difference (a-vO2 difference), therefore increases. As a result, the Oxygen Transport Study value for (a-v)O2 difference increases, indicating impaired oxygen delivery to the tissues.
