Blood gas analysis

A venipuncture performed using a vacutainer Venipuncture is useful as it is a minimally invasive way to obtain cells and extracellular fluid plasma from the body for analysis.

This article has been cited by other articles in PMC. Abstract Disorders of acid—base balance can lead to severe complications in many disease states, and occasionally the abnormality may be so severe as to become a life-threatening risk factor.

The process of analysis and monitoring of arterial blood gas ABG is an essential part of diagnosing and managing the oxygenation status and acid—base balance of the high-risk patients, as well as in the care of critically ill patients in the Intensive Care Unit. Since both areas manifest sudden and life-threatening changes in all the systems concerned, a thorough understanding of acid—base balance is mandatory for any physician, and the anesthesiologist is no exception.

However, the understanding of ABGs and their interpretation can sometimes be very confusing and also an arduous task. Many methods do exist in literature to guide the interpretation of the ABGs. The proper application of the concepts of acid—base balance will help the healthcare provider not only to follow the progress of a patient, but also to evaluate the effectiveness of care being provided.

The usefulness of this diagnostic tool is dependent on being able to correctly interpret the results.

Blood gas analysis, also called arterial blood gas (ABG) analysis, is a test which measures the amounts of oxygen and carbon dioxide in the blood, as well as the acidity (pH) of the blood. Arterial blood gases (ABGs) are an important routine investigation to monitor the acid-base balance of patients. They may help make a diagnosis, indicate the severity of a condition and help to assess treatment. An arterial-blood gas (ABG) test measures the amounts of arterial gases, such as oxygen and carbon dioxide. Arterial blood for blood-gas analysis is usually drawn by a respiratory therapist and sometimes a phlebotomist, a nurse, a paramedic or a heartoftexashop.com:

According to the principle of electrical neutrality, this difference is balanced by the weak acids and CO2. This is familiarly known as anion gap AGwhen normal concentration is actually caused by A.

Thus all the three methods yield virtually identical results when they are used to quantify acid—base status of a given blood sample. The utilization of an ABG analysis becomes necessary in view of the following advantages: Aids in establishing diagnosis.Arterial blood gas (ABG) analysis is an essential part of diagnosing and managing a patient’s oxygenation status and acid–base balance.

Arterial blood gas test - Wikipedia

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. Arterial whole blood is almost always used for blood gas analysis but, in some cases, as with babies, whole blood from a heelstick is collected instead.

How to Prepare for the Test

Blood may also be . Arterial blood for blood-gas analysis is usually drawn by a respiratory therapist and sometimes a phlebotomist, a nurse, a paramedic or a doctor. Blood is most commonly drawn from the radial artery because it is easily accessible, can be compressed to control bleeding, and has less risk for occlusion.
