Arterial blood is used to assess the state of oxygenation and acid-base balance, (information on oxygenation, level of the carbon-dioxide and information on pulmonary and renal function). Blood gas measurement is done if you are known to have a respiratory condition (e.g. chronic obstructive disease, bronchial asthma exacerbation, acute bronchitis, pneumonia, and pulmonary fibrosis), metabolic or renal condition, in order to assess oxygenation and acid-base balance. Patients in long term oxygen therapy (receiving supplemental oxygen) may be subjected to blood gas measurement from time to time, to check the effectiveness of treatment.
