What is ABG values in nursing?
An arterial blood gases (ABG) test is a blood test that measures the acidity, or pH, and the levels of oxygen (O2) and carbon dioxide (CO2) from an artery. The test is used to check the function of the patient’s lungs and how well they are able to move oxygen into the blood and remove carbon dioxide.
What is the normal range of ABGS?
7.35 – 7.45
Normative Values
| Arterial Blood Analysis | Reference Ranges | Reference Ranges |
|---|---|---|
| pH | 7.35 – 7.45 | 7.31 – 7.41 |
| PaO2 | 10.7 – 13.3 kPa | 5.0 – 5.6 kPa |
| PaCO2 | 4.7 – 6.0 kPa | 5.6 – 6.7 kPa |
| Bicarbonate (HCO3-) | 22 – 26 mmol/L |
What do blood gases tell you?
A blood gas test provides a precise measurement of the oxygen and carbon dioxide levels in your body. This can help your doctor determine how well your lungs and kidneys are working. This is a test that is most commonly used in the hospital setting to determine the management of acutely ill patients.
How do you interpret ABG base excess?
A high base excess (> +2mmol/L) indicates that there is a higher than normal amount of HCO3– in the blood, which may be due to a primary metabolic alkalosis or a compensated respiratory acidosis.
What do ABGS measure?
An arterial blood gases (ABG) test measures the acidity (pH) and the levels of oxygen and carbon dioxide in the blood from an artery. This test is used to find out how well your lungs are able to move oxygen into the blood and remove carbon dioxide from the blood.
How do I report ABG?
Documenting the ABG results in the notes
- Document the time and date that the ABG was performed as this may be significantly different from the time you are documenting.
- Write the indication for the ABG (e.g. hypoxia).
- Document the ABG results and your interpretation of them (see our guide to ABG interpretation):
What are the two most important blood gases?
Oxygen (O2) and carbon dioxide (CO2) are the most important respiratory gases, and their partial pressures in arterial blood reflect the overall adequacy of gas exchange.
What does an ABG show?
An arterial blood gases (ABG) test is a blood test. It measures the acid-base balance (pH) and the levels of oxygen and carbon dioxide in the blood. It uses blood drawn from an artery. This is where the levels of oxygen and carbon dioxide can be measured before they enter body tissues.
