Web13 dec. 2024 · Purpose of the test. The purpose of a blood gases test is to evaluate the amount of oxygen and carbon dioxide and the acid-base balance, or pH, in the blood. Blood gases testing is primarily used for diagnosis and monitoring of different medical conditions. Diagnosis is the process of finding the cause of a person’s health problems. WebA low PaO 2 indicates that the patient's current minute ventilation (whether high or normal) is not enough to allow adequate oxygen diffusion into the blood. Therefore, the A–a gradient essentially demonstrates a high respiratory effort (low arterial PaCO 2) relative to the achieved level of oxygenation (arterial PaO 2 ).
