Blood Gas Analysis is also called Arterial Blood Gas Analysis (ABG), which measures the amount of Oxygen & Carbon dioxide in the blood and also measures the pH of the blood.

Blood gas analysis is performed on blood collected from the artery. It measures the partial pressure of Oxygen and Carbon dioxide in the blood, as well as Oxygen content, Oxygen saturation, Bicarbonate content and Blood pH.

Oxygen in the lungs is carried to the tissues through the bloodstream, but only a small fraction of this oxygen dissolves in the arterial blood. How much dissolving depends on the partial pressure of oxygen, therefore, testing the partial pressure of Oxygen indicates how much Oxygen the lungs deliver to the blood. Carbon dioxide is released into the blood as a by-product of cell metabolism. Partial Carbon dioxide pressure indicates how well the lungs are...
