ABG Done

Collected For:

Definition:

An analysis of the pH, concentration and pressure of oxygen, carbon dioxide, and hydrogen ions in the blood. It is used to assess acid-base balance and ventilatory status in a wide range of conditions. Arterial blood gas (ABG) determination is performed on arterial, rather than venous blood. Documentation of arterial blood gas analysis performed within 24 hours of arrival may be used for this measure. If no ABG was performed within 24 hours after arrival, then the results up to 24 hours prior to arrival may be used.
