Oxygen Saturation Test

An Oxygen Saturation Test measures the amount of oxygen in your blood, which is crucial for understanding how well your lungs are working. During the test, a small device called a pulse oximeter is placed on your fingertip or earlobe. It uses light to assess how much oxygen is bound to your red blood cells. The results, shown as a percentage, indicate whether your lungs are effectively delivering oxygen to your body. This test is often part of pulmonary function testing to help diagnose or monitor respiratory conditions.
