His breathing was labored, pulses rapid and weak, and his skin was cold and clammy.An ECG was done which revealed significant “Q” waves in most leads. Troponin level was elevated.

The essential difference between venous and arterial blood is the curve of the oxygen saturation of . The difference in the oxygen content of the blood between the arterial blood and the venous blood is known as the The arteriovenous oxygen difference, or a-vO2 diff, is the difference in the content of the between the and the . It is an indication of how much oxygen is removed from the blood in as the blood in the body. The a-vO2 diff and are the main factors that allow variation in the body’s total oxygen consumption, and are important in measuring . The a-vO2 diff is usually measured in of oxygen per 100 millilitres of blood
