![]() Although oxygenation and ventilation can be assessed non-invasively via pulse oximetry and end-tidal carbon dioxide monitoring, respectively, ABG analysis is the standard. PaCO2 is affected by hyperventilation (rapid or deep breathing), hypoventilation (slow or shallow breathing), and acid-base status. ![]() PaO2 provides information on the oxygenation status, and PaCO2 offers information on the ventilation status (chronic or acute respiratory failure). ABG analysis assesses a patient's partial pressure of oxygen (PaO2) and carbon dioxide (PaCO2). An arterial blood gas (ABG) tests explicitly blood taken from an artery. Ī "blood gas analysis" can be performed on blood obtained from anywhere in the circulatory system (artery, vein, or capillary). ![]() Understanding and use of blood gas analysis enable providers to interpret respiratory, circulatory, and metabolic disorders. Blood gas analysis is a commonly used diagnostic tool to evaluate the partial pressures of gas in blood and acid-base content.
