What To Expect Before Lung Function Tests

If you take breathing medicines, your doctor may ask you to stop them for a short time before spirometry, lung volume measurement, or lung diffusion capacity tests.

No special preparation is needed before pulse oximetry and arterial blood gas tests. If you're getting oxygen therapy, your doctor may ask you to stop using it for a short time before the tests. This allows your doctor to check your blood oxygen level without the added oxygen.
