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.

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. Disorders of acid—base balance can create complications in many disease states, and occasionally the abnormality may be so severe so as to become a life-threatening risk factor. A thorough understanding of acid—base balance is mandatory for any physician, and intensivist, and the anesthesiologist is no exception. According to the principle of electrical neutrality, this difference is balanced by the weak acids and CO2.

This is familiarly known as anion gap AG , when 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.

Interpretation of arterial blood gas

Kelkis The influence of anticoagulation on acid-base status gsaometry blood-gas analysis. ABG testing is mainly used in pulmonology and gaeometry medicine to determine gas exchange across the alveolar-capillary membrane. By using this site, you agree to the Terms of Use and Privacy Policy. National Committee for Clinical Laboratory Standards. In addition, the arterial oxygen saturation can be determined. If a person is in a critical setting and intubated, one must increase the number of breaths mechanically. Thus when an arterial blood gas test reveals, for example, an elevated bicarbonate, the problem has been present for a couple of days, and metabolic compensation took place over a blood gasomerty problem.
