A pulmonary artery oxygen saturation of 75% indicates that the blood flowing from your heart to your lungs through the pulmonary arteries is carrying a reduced amount of oxygen. This is actually normal for pulmonary arteries, as they are unique - they're the only arteries in the body that carry oxygen-poor blood.

The pulmonary arteries' job is to transport this deoxygenated blood from your heart to your lungs, where it will pick up more oxygen. Once the blood gets to your lungs and becomes oxygenated, it returns to your heart through the pulmonary veins to be pumped out to the rest of your body.
