O2 sat on room air or arterial blood would be lower than normal. CO2 levels would be higher.

No Blood gases are measured to determine the oxygen concentration in the arterial blood. Therefore the blood must be drawn from an artery.

PO2 in blood is the amount of gases in your blood. In medical terms, this is commonly called the Alveolar-arterial.
In arterial blood cells Oxygen. In venous blood cells Carbon Dioxide.
The acronym ABG stands for Arterial Blood Gases.
Decreased Oxygen, increased CO2, Acidosis
After the drawing of an arterial sample, the artery should immediately be compressed for a minimum of one minute to two minutes to prevent a hematoma.
Since one of the ideas of an arterial line is to check on blood gases (O2 saturation mainly), placing a line in the pulmonary artery would counteract this idea. Arteries are called such since they carry blood AWAY from the heart, etc.
