Arterial blood gas (ABG) analysis is a critical test that measures the levels of oxygen, carbon dioxide, and the pH of blood from an artery, providing essential information about a patient's respiratory and metabolic state. It is particularly valuable in assessing and managing conditions affecting the lungs, kidneys, and metabolism, helping guide treatment decisions in acute and chronic illnesses.
Acid-base disorders are imbalances in the body's acid-base homeostasis, typically classified as acidosis or alkalosis, and can be either metabolic or respiratory in origin. Diagnosis and management require understanding the underlying cause, which involves evaluating arterial blood gases and the anion gap, to restore normal pH levels and address the root problem.
