analysis is usually one of the first tests ordered to assess respiratory
status because it helps evaluate gas exchange in the lungs.

-Partial pressure of arterial carbon dioxide
-Partial pressure of arterial oxygen
-Bicarbonate level
What does pH show in an ABG analysis? Correct Answer-pH is an
indication of hydrogen ion concentration in the blood and shows the
blood's alkalinity or acidity.
What does the partial pressure of arterial carbon dioxide reflect in an
