What is arterial blood gas?

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.

What is the medical term for arterial blood gases?

What are normal arterial blood gases?

According to the National Institute of Health, typical normal values are:

pH: 7.35-7.45.
Partial pressure of oxygen (PaO2): 75 to 100 mmHg.
Partial pressure of carbon dioxide (PaCO2): 35-45 mmHg.
Bicarbonate (HCO3): 22-26 mEq/L.
Oxygen saturation (O2 Sat): 94-100%

What is a good blood gas level?

The following are normal ranges for results of a blood gas test: pH: 7.35–7.45. partial pressure of oxygen (PaO2): 80–100 millimeters of mercury (mmHg) partial pressure of carbon dioxide: 35–45 mmHg.

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 is the normal level of arterial blood gas?

Normal arterial oxygen pressure (PaO2) measured using the arterial blood gas (ABG) test is approximately 75 to 100 millimeters of mercury (75-100 mmHg). When the level goes below 75 mmHg, the condition is generally termed as hypoxemia. Levels under 60 mmHg are considered very low and indicate the need for supplemental oxygen.

What does arterial blood gas mean?

An arterial blood gas ( ABG ) is a type of blood test which measures the pH or acidity of the blood, as well as gases, such as oxygen and carbon dioxide. The test is usually performed on people if they have breathing problems, such as emphysema and asthma.

What is the normal range of arterial blood?

The normal range for arterial blood pH is 7.35 to 7.45. A pH greater than 7.45 indicates alkalosis or more alkaline blood and a pH below 7.35 indicates acidosis or more acidic blood.
