Oxygen Saturation

What is *oxygen saturation*?

% of oxygen in blood.

What is the oxygen saturation in the *coronary sinus*? And why this amount?

About 60%, the lowest level in the body due to myocardium extracting the highest oxygen in body circulation.

What is *oxygen consumption*?

Amt. of oxygen (in ml) extracted from the air in one minute.

What is *oxygen content*?

Amt. of oxygen measured in volume: ml O2/ 100 ml of blood.

In the left heart, what is % of oxygen saturation? Please list the cardiac structures.

The *pulmonary veins, left atrium, left ventricle, and aorta* have an oxygen saturation of 98%.

In the right heart, what is % of oxygen saturation? Please list the cardiac structures.

The *vena cava, right atrium, right ventricle, and main pulmonary artery* have an oxygen saturation of approximately *75*%.
