Stress ABG Measurement
How to prepare for your test:
Do not eat or drink after midnight the night before the test. No caffeine for at least 12 hours, and preferably 24 hours, before the test. Wear comfortable walking shoes and two-piece clothing since you will be required to exercise as part of the test. Unless your doctor advises you otherwise, continue taking your medications as usual.
How long will the test take?
About 1 hour.
What is the purpose of the test?
The ABG (arterial blood gas) test measures oxygen, carbon dioxide, and acid in the blood, which helps show how the lungs are working.
How is the test performed?
A small area on the inside of one of your wrists may be numbed with anesthetic. Then a lab phlebotomist will draw blood from this artery.
You will be asked to walk on a treadmill (or pedal a stationary bike). The tread will move slowly at first, and then the speed and incline will gradually increase (or, if you are on a bike, the pedal resistance will gradually increase). You will exercise for about 6 minutes. Then the phlebotomist will draw another arterial blood sample from your wrist.
Your blood samples will be taken to the Laboratory for analysis.
In case of schedule delays:
We do our best to start your procedure on schedule, but sometimes another patient may experience a cardiac emergency that delays your procedure. If a delay occurs, we will keep you informed of changes and will start your procedure as soon as possible.
A place for family and friends:
You are welcome to bring a family member or friend to your test. Our Heart Center also has a comfortable waiting area.
Your test will be conducted at:
EIRMC Heart Center
2nd Floor (above Emergency Dept.)
3100 Channing Way, Idaho Falls
