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.

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.

How does sleep apnea affect arterial blood gas?

When taken? If the blood gas is taken while the person is awake, the results are likely to be normal unless there is an underlying breathing or lung disorder. If taken while asleep, it could show a low oxygen level, a higher than normal co2 level, but these changes are constantly fluctuating on a breath by breath basis. Read more...
Can temporarily lower 02. When someone is having apnea they stop breathing and this can cause a decrease in the blood oxygen and an increase in the blood carbon dioxide. Once they start breathing again usually this corrects itself fairly quickly. Read more...

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.

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...

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...

Does it hurt to get an arterial blood gas done?

Just a needle stick. An arterial blood gas (abg) is a blood draw from an artery rather than a vein. For some there is slightly more discomfort with an abg than there is with a routine blood draw. For others there is less pain. Read more...
