Bicarbonate

How To Prepare

Tell your doctor if you:

• Have had bleeding problems or take blood thinners, such as aspirin or warfarin (Coumadin).
• Are taking any medicines.
• Are allergic to any medicines, such as those used to numb the skin (anesthetics).

If you are using oxygen, it may be turned off for 20 minutes before an arterial blood gas test. This is called a "room air" test. If you cannot breathe without the oxygen, it will not be turned off.

Talk to your doctor about any concerns you have regarding the need for the test, its risks, how it will be done, or what the results may mean. To help you understand the importance of this test, fill out the medical test information form(What is a PDF document?).
