Arterial blood gas analyses
-assesses a patient’s partial pressure of oxygen (PaO2), providing information on the oxygenation status
-the partial pressure of carbon dioxide (PaCO2), providing information on the ventilation status (chronic or acute respiratory failure, and is changed by hyperventilation (rapid or deep breathing) and hypoventilation (slow or shallow breathing);
-acid-base status.
– oxygenation and ventilation can be assessed non-invasively via pulse oximetry and end-tidal carbon dioxide monitoring, respectively, blood gas analysis is the standard.
