ABGanalüüsi

ABGanalüüsi, commonly known as Arterial Blood Gas analysis, is a laboratory test that measures the levels of oxygen and carbon dioxide in the blood, as well as the blood's pH. This test is crucial for evaluating a patient's respiratory and metabolic status. It is typically performed by drawing blood directly from an artery, most commonly the radial artery in the wrist.

The analysis provides vital information about how well the lungs are oxygenating the blood and how effectively the body is removing carbon dioxide. It also assesses the acid-base balance of the blood, indicating whether the body is too acidic (acidosis) or too alkaline (alkalosis). These imbalances can be caused by a variety of conditions, including respiratory diseases like pneumonia or COPD, metabolic disorders such as diabetes, or even certain medications.

Interpreting ABG results involves looking at several key values: pH, partial pressure of oxygen (PaO2), partial pressure of carbon dioxide (PaCO2), bicarbonate (HCO3-), and oxygen saturation (SaO2). Deviations from normal ranges can help clinicians diagnose and monitor a wide range of critical illnesses and guide treatment decisions, particularly in intensive care settings. The test is quick to perform, though the interpretation requires medical expertise.
