What does oxygen saturation indicate?
Understand the Problem
The question is asking for the meaning of oxygen saturation and what it indicates in terms of blood content and gas binding. The answer choices provide various options related to oxygen and carbon levels in the blood.
Answer
Oxygen saturation shows the percentage of hemoglobin in the blood bound to oxygen.
The final answer is that oxygen saturation indicates the percentage of hemoglobin in the blood that is currently bound to oxygen, reflecting how well oxygen is being transported from the lungs to the rest of the body.

More Information
Oxygen saturation is often checked using a pulse oximeter, a non-invasive tool that clips onto a body part, like a finger. Normal saturation levels typically range from 95% to 100%. Levels below this range might indicate a problem with lung function or circulation.
Tips
A common mistake is confusing oxygen saturation with the actual oxygen concentration in the blood or mistaking it for blood pressure.
