Artery (Definition)

Arteries are defined as blood vessels which carry blood away from the heart (to either the body or lungs). Arteries: higher pressure, thicker walls, stretch (pulse) with each heart contraction & deliver blood to the arterioles which control the flow to individual capillaries. Veins are blood vessels which carry blood from capillaries back to the heart (body to right heart; ...Read more

What are the normal ranges in arterial blood gas?

What are the normal ranges in arterial blood gas?

See below: Here are the "ideal" values. However, it all depends on the situation and the relationships between the numbers (i.e. Is the body compensating appropriately for the situation). Ph: 7.35-7.45, po2 80-120, pco2 38-42, hco3 22-28. ...Read more

I had an arterial blood gas drawn today and now my wrist is really swollen. It only hurts a little. Is this normal or cause for concern?

I had an arterial blood gas drawn today and now my wrist is really swollen. It only hurts a little. Is this normal or cause for concern?

Hematoma wrist: its difficult to tell without seeing you, the main concern is that blood leaks enough to cause compression on the nerved and blood supply to the hand. the important things to look at in the speed of progress of the swelling, or development of pain, pain on passive stretch of muscles in the hand. I suggest urgent medical review ...Read more

Arterial blood gas showed my pO2 was HIGH at 103. How is this possible? I'm not on oxygen therapy or anything like that. I was breathing normally.

Arterial blood gas showed my pO2 was HIGH at 103. How is this possible? I'm not on oxygen therapy or anything like that. I was breathing normally.

High PO2 level: It is important to know the rest of the blood gas test results. pH? pCO2? Bicarbonate? Your doctor can put it all in perspective for you. What was the O2 sat? If low, it might point to a methemoglobinemia, perhaps from some meds you take. Best to discuss the entire blood gas study with your provider. Normal PO2 shouldn't be above 102. . ...Read more

I had an arterial blood gas sample about 9 days ago. I still have a large bruise on my wrist over the artery where the sample was collected. normal?

Next time some else: The next you need to get blood drawn have a different phlebotomist draw it and after it is drawn and you are given a cotton pad to hold over the insertion site hold it there FIRMLY for 10 minutes! Good luck. This is a bloody business you know! ...Read more

Arterial blood gas results: PH- 7.431, pCO2- 40.1, HCO3- 26.1, BE- 1.7. Are these normal or elevated? Could this cause Ventricular tachycardia?

Arterial blood gas results: PH- 7.431, pCO2- 40.1, HCO3- 26.1, BE- 1.7. Are these normal or elevated? Could this cause Ventricular tachycardia?

Normal blood gas ABG: The result you've provided so far seem within the reference range for most blood gas machines - so, "average". One result you didn't list is the pO2, which is a measure of the oxygen content of arterial blood. A low pO2 can cause ventricular tachycardia (VT); however, I suspect the ABG was used as part of a wider panel of tests to help determine cause of VT. Talk to the doctor who ordered the test ...Read more

Can high o2 affinity hemoglobin cause arterial blood gas values of high o2?

Can high o2 affinity hemoglobin cause arterial blood gas values of high o2?

Less O2 delivery: High o2 affinity HGB (leftward shift in o2 saturation curve) means it requires a higher partial pressure of o2 to achieve the same o2 saturation. The HGB is more tightly bound to o2 and less is delivered to the tissues. More o2 will be necessary to adequately deliver oxygen to the tissues. ...Read more

Arterial blood gas, what is this?

Arterial blood gas, what is this?

Mearsurment: THe sampling of blood from an artery gives the tester a clue as to how much oxygen your cells are carrying, the level of Co2 to see if respiration and acid base balance is in check. ABG is often performed during asthma to see the pulmonary status and whn one is on a ventilatr to breathe. It can ensure the ventilator is producing enough ventialtion ...Read more

What ia an ?Arterial blood gas exam?

Blood oxygen test.: An abg is a test that measures the oxygen tension, carbon dioxide, and acidity (ph) of blood taken from an artery. It is used to determine how well the blood is being oxygenated and how well gas exchange is occuring. This information is vital when caring for patients with critical illness or respiratory disease. ...Read more

How can I explain arterial blood gas?

How can I explain arterial blood gas?

Blood Gases: I am not sure what context you are asking about. The questions is very ambiguous. What specifically prompts this question? But, blood gases tell the medical team how well the oxygen and carbon dioxide balance is being maintained in the body. It can tell how the fragile balance of being acidic or basic is in a sick person. It is used in many instances in the hospital with very ill patients. ...Read more

A bit: Arteries are more muscular than veins and have a higher pressure inside. The arterial stick is not much different than a venous blood draw but it has to be held with pressure plus have a pressure dressing afterward. ...Read more

How can you interpret a arterial blood gas test?

How can you interpret a arterial blood gas test?

Difficult: Interpreting blood gas results requires a thorough knowledge of respiratory physiology, metabolic alterations, changes due to body making compensation for the abnormalities and effect of various interventions. Arterial blood gas results is not something to be interpreted by a lay person. ...Read more

What are they looking for in a arterial blood gas?

O2/CO2 exchange: Abg is used for two purposes: 1) how your lungs are handling the exchange of oxygen and carbon dioxide 2) the acid/base metabolism affected by breathing and various metabolic disturbances (eg., diabetic coma, toxic ingestion of substances, sepsis). ...Read more

Is it true that an arterial blood gas of 92% is bad?

Is it true that an arterial blood gas of 92% is bad?

Yes: Its not horribly bad but bad enough that something has to be done to raise the oxygen level in the hemoglobin. We consider the oxygen to be low at 60 which coincides with a blood gas of 90 thus at 92 you are nearing a bad level ...Read more

Arterial blood gas question? Do they stick you for it?

Arterial blood gas question? Do they stick you for it?

Yes: As the name implies, an arterial blood gas is when they check your gas levels (oxygen and carbon dioxide) from the blood in your arteries. Therefore, you must be stuck with a needle in your artery (usually the radial artery for an adult). The only time you wouldn't be stuck for it is if you already have a special IV line (arterial line) in place - but then you're most likely in the icu. ...Read more

Why is an modified allen's test performed when drawing arterial blood gas?

Why is an modified allen's test performed when drawing arterial blood gas?

To avoid ischemia: Allen test is done to ensure that dual arterial blood supply to the hand is intact. If both and radial and ulner arteries are not intact and if the remaining artery is damaged it could disable the hand, therefore allen test is essential to ensure adequate blood supply to the hand in case of injury to the artery from which blood may be drawn. ...Read more

How does smoking affect arterial blood gas results?

How does smoking affect arterial blood gas results?

Measure CO level: An arterial blood gas measures the blood pH (normal 7.40), po2 (partial pressure of oxygen), pco2, partial pressure of co2 and the bicarbonate (sodium bicarbonate) level is calculated. Smoking increases carboxyhemoglobin level with carbon monoxide binding to the hemoglobin displacing oxygen. The po2 is unaffected by carbon monoxide but the hemoglobin delivers carbon monoxide (a poison) to tissues instead of oxygen. ...Read more
