What is an Arterial Blood Gas (ABG)? An ABG is a blood test that measures the acidity, or pH, and the levels of oxygen (O2) and carbon dioxide (CO2) from an artery.² 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.

When interpreting arterial blood gas (ABG) results, it is essential to know what ABG values are considered ‘normal’. From this baseline, you can then begin to recognise significant variations in a patient’s results, which could indicate clinical deterioration.

A high base excess (> +2mmol/L) indicates that there is a higher than normal amount of HCO 3 – in the blood, which may be due to a primary metabolic alkalosis or a compensated respiratory acidosis. A low base excess (< -2mmol/L) indicates that there is a lower than normal amount of HCO 3 – in the blood, suggesting either a primary metabolic acidosis or a compensated respiratory alkalosis.

Interpreting an arterial blood gas (ABG) is a crucial skill for physicians, nurses, respiratory therapists, and other health care personnel. ABG interpretation is especially important in critically ill patients. The following six-step process helps ensure a complete interpretation of every ABG.

UNDERSTANDING ARTERIAL BLOOD GASES An arterial blood gas is taken to measure the pH of arterial blood. The pH is a measurement of the acidity or alkalinity of the blood. It is inversely proportional to the number of hydrogen ions (H+) in the blood. The more H+ present, the lower the pH will be.

Understanding arterial blood gases. This article examines acid-base balance and the interpretation of arterial blood gases (ABG). The article begins with a brief revision of related physiology followed by a description of the primary disorders of acid-base balance. The normal ranges and the significance of abnormal ABG results are exp ….

Your doctor may run a blood gas analysis or arterial blood gas (ABG) test if you are showing the signs of an oxygen, carbon dioxide, or pH imbalance such as confusion or difficulty breathing. This test measures the partial levels of these substances using a small blood sample.

Arterial oxygen tension (PaO 2) is the partial pressure of oxygen in arterial blood. The main determinants of PaO 2 are the inspired oxygen concentration, alveolar gas exchange, and, to a lesser extent, tissue oxygen consumption.

Arterial blood gas (ABG) testing is a diagnostic test performed on blood taken from an artery that provides a glimpse of how much oxygen and carbon dioxide are in your blood, along with your blood's pH level. ABG tests are used to evaluate respiratory and kidney functions and give an overall look into the body's metabolic state. 1 

The PaO2 and PaCO2 are the partial pressure (a measure of dissolved gas) of oxygen and carbon dioxide in the blood. In an arterial sample, the PaO2 should be about 10 in a healthy person breathing air. For those on oxygen, a rough guide is about 10 less than the percentage of inspired oxygen (so someone on 40% FiO2 should have a PaO2 of about 30).

Arterial blood gas nursing?

An Arterial Blood Gas requires the nurse to collect a small sample of blood - generally, a full 1 ml³ is preferred. Blood can be drawn via an arterial stick from the wrist, groin, or above the elbow. The radial artery on the wrist is most commonly used to obtain the sample. However, the femoral artery and brachial artery can be used if necessary.

Arterial blood gas results?

An arterial blood gas test, commonly known as an ABG, is performed on blood that is drawn from an artery. It is used to see how well the lungs are functioning and to determine the effectiveness of respiratory therapies, such as the use of a ventilator, CPAP, BiPAP, or oxygen. A blood gas may also reveal the presence of kidney problems, but is not typically performed to diagnose problems with the kidneys.
