What is the normal range of arterial blood gas?
Normal Results Values at sea level: Partial pressure of oxygen (PaO2): 75 to 100 millimeters of mercury (mm Hg), or 10.5 to 13.5 kilopascal (kPa) Partial pressure of carbon dioxide (PaCO2): 38 to 42 mm Hg (5.1 to 5.6 kPa) Arterial blood pH: 7.38 to 7.42.
How do I interpret my arterial blood gas results?
If the ABG results reveal pH numbers are not within the normal range, the patient’s pH level is either acidotic or alkalotic. The lower the number, the more acidotic the patient is. For instance, a pH of 3 is severely acidotic and requires emergency intervention. Alkalosis is the opposite.
What is normal arterial CO2?
The normal range is 23 to 29 milliequivalents per liter (mEq/L) or 23 to 29 millimoles per liter (mmol/L). Normal value ranges may vary slightly among different laboratories.
What is normal range of pO2 and PCO2?
ABG (Arterial Blood Gas)
| pH | 7.31–7.41 | |
|---|---|---|
| pCO2 | 41–51 torr | 5.5–6.8 kPa |
| pO2 | 30–40 torr | 4.0–5.3 kPa |
| CO2 | 23–30 mmol/L | |
| Base excess/deficit | ± 3 mEq/L | ± 2 mmol/L |
What is considered hypoxia on ABG?
Like most medical normal values and ranges, the definition can vary slightly, but generally the following definitions apply: Mild hypoxemia: PaO2 = 60 to 79 mmHg. Moderate hypoxemia: PaO2 = 40 to 59 mmHg. Severe hypoxemia: PaO2 < 40 mmHg.
Do ABGS need to be put on ice?
It is essential that the ABG sample be run within 10-15 minutes or immediately be put in a container of ice. An ABG sample can remain stable on ice for at least 1 hour.
When should an ABG be checked?
Your doctor may ask for an arterial blood gas test to: Check for severe breathing and lung problems such as asthma, cystic fibrosis, chronic obstructive pulmonary disease (COPD), or obstructive sleep apnea. Check how treatments for your lung problems are working.
What are the ABG values for COPD?
Persons with COPD are typically separated into one of two catagories: “pink puffers” (normal PaCO2, PaO2 > 60 mmHg) or “blue bloaters” (PaCO2 > 45 mmHg, PaO2 < 60 mmHg). Pink puffers have severe emphysema, and characteristically are thin and free of signs of right heart failure.
How to interpret arterial blood gas?
A blood gas test measures the amount of oxygen and carbon dioxide in the blood. It may also be used to determine the pH of the blood, or how acidic it is. The test is commonly known as a blood gas analysis or arterial blood gas (ABG) test. Your red blood cells transport oxygen and carbon dioxide throughout your body. These are known as blood gases.
What is the normal level of arterial blood gas?
The normal level for bicarbonate is between 22 to 26 milliEquivalents Per Liter (mEq/L). A disruption of your bicarbonate levels may indicate conditions such as respiratory failure, anorexia , and liver failure. An HCO3 level is below 24 mEq/L indicates metabolic acidosis.
What is the normal value of arterial blood gas?
Values that fall outside of the normal range, as well as shifts in blood pH that occur as a result are referred to as abnormal blood gases. The first step in evaluating a blood gas report is to look at pH. The normal range for arterial blood pH is 7.35 to 7.45.
What would an arterial blood gas test reveal?
A blood gas test is also called an arterial blood gas test or a blood gas analysis. It measures oxygen and carbon dioxide levels in the blood. The test can also show blood pH levels and lung function .
