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

Artery (Definition)

Arteries are a type of blood vessels. We can divide blood vessels into 2 categories. Arteries are high pressure vessels which deliver (red) oxygen + blood out into the body. Veins on the other hand or low pressure vessels which return (dark) oxygent - blood from the body ...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

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

What ia an ?Arterial blood gas exam?

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

What are they looking for in a arterial blood gas?

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

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

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

How would oxygen deprivation change arterial blood gas levels?

How would oxygen deprivation change arterial blood gas levels?

Breath rate increase: O2 deprivation will typically cause people to breath faster. Abg measures levels of oxygen, carbon dioxide and blood ph. Faster breathing causes a drop in co2 which then causes the blood to have an increase in ph (towards basic, not acidic). Over time, the body would compensate for this ph change via acid retention by the kidney and although the co2 would remain low, the ph would approach normal. ...Read more

When would you look at cord venous blood gas levels and arterial blood gas levels?

When would you look at cord venous blood gas levels and arterial blood gas levels?

Difficult delivery: These tests are used to help predict how difficult the delivery was for the baby. Any difficult delivery will often have cord gases taken; if baby is showing signs of distress, then an arterial blood gas from baby may be taken as well. ...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
