This is a test that measures the levels of oxygen and carbon dioxide (the bodies waste gas) as well as the ph of the blood. All of these things must be kept within certain ranges and disturbances in them can indicate certain ...Read more

Can an abg be preformed at sleep?

Can an abg be preformed at sleep?

Yes but...: An arterial blood gas (abg) can be performed awake or asleep. This can be a somewhat painful blood test and one would likely not be able to stay asleep while being performed.

Why does someone in ER need abg? Can you refuse it if other tests ok?

Why does someone in ER need abg? Can you refuse it if other tests ok?

See below: An arterial blood gas (abg) is used to detect the oxygenation in blood and see if there is any discrepancy to that obtained from the lungs (via a finger or ear oxygen sensor). If so, it could be something like a blood clot in the lungs. It also tells you your carbon dioxide level and blood acidity. You can refuse any test you want. ...Read more

Where do I go to get an abg done?

Where do I go to get an abg done?

Follow equipment: An abg (arterial blood gas) is a specialized type of blood draw from an artery, so you need an experienced medical professional with training/experience. This lab is usually run immediately for accuracy, so it needs to be done on site where there is a blood gas machine. Places that might have this would be doctor's offices or clinics, pulmonary labs, labs, hospitals, ers, instant care facilities. ...Read more

Where is an abg usually done? At a hospital?

Where is an abg usually done? At a hospital?

Yes: A specialized piece of lab equipment called a co-oximeter is required to analyze the amount of oxygen and carbon dioxide in arterial blood. Also the blood must be drawn from an artery, not a vein, and not everyone is trained to obtain this kind of sample. ...Read more

Is it ok to have an abg done two days in a row in the same arm.?

Is it ok to have an abg done two days in a row in the same arm.?

Yes: In general, the artery heals quite quickly. The odds of placing the abg needle in exactly the same spot is quite low. So -- it is ok to have arterial blood draws from the same artery, as long as you apply pressure for a good length of time (8-10 minutes). ...Read more

For someone placed on a mechanical ventilator, when is best time to check abg?

For someone placed on a mechanical ventilator, when is best time to check abg?

Depends: It depends on the reason why the patient was placed on the ventilator in the first place and how they respond. Sometimes an abg is obtained only a few minutes after being placed on a ventilator (e.g. After an emergency intubation); often, an abg is not needed at all (e.g. Intubated for an elective procedure requiring general anesthesia). ...Read more

Can a patients 02sat be in the high 90's while the patients abg shows a po2 in the 50's? And what could cause this?

Can a patients 02sat be in the high 90's while the patients abg shows a po2 in the 50's? And what could cause this?

Several issues: The po2 may not be accurate because it includes venous blood. The spo2 may not be accurate because carbon monoxide is read as o2. The oximeter has many potential errors. Motion, light and other issues can create abnormal values. ...Read more

Would all patients admitted with COPD exacerbation get abgs drawn up?

Would all patients admitted with COPD exacerbation get abgs drawn up?

Interesting question: If you ask me, most if not all such patients should get abgs. Physicians practice differently though and not all do this. There are no hard guidelines and standard of care for that as far as I am aware, unless the patient is in respiratory failure/intubated where abgs guide the management. ...Read more

Is there a way to estimat a patient Po2 from a ABG? Example if you have a mixed venous specimen?

Not really: Estimating the pO2 would be very inaccurate, especially if its from a venous sample. There is no way to tell what your arterial level is based on the venous level. ...Read more
