It’s appropriate to focus on arterial blood gas analysis to understand how effectively the lungs oxygenate the blood. But equally important is the test’s value in assessing the elimination of the principal metabolic product of aerobic metabolism—carbon dioxide. The arterial carbon dioxide level is a critical parameter in the other major application of arterial blood gas testing—the analysis of your patient’s acid-base status. The articles in this chapter of our Blood Gas Analysis Clinical Guide, review the principal determinants of arterial PCO2.
Unsure how to determine arterial carbon dioxide tension in your patients? In this article, learn how to calculate PaCO2 with minute ventilation.
In this Medmastery Clinical Guide article, learn how carbon dioxide is transported through the blood in its three primary forms. 
Looking at arterial oxygen tension is just one aspect of blood gas analysis. In addition to its valuable role in assessing respiratory function, arterial blood gas analysis is vitally important in evaluating acid-base balance. The articles in this chapter describe the relationship between arterial PCO2 and ventilation, in particular, alveolar ventilation. The relationship between arterial PCO2 and pH is reviewed, as are the roles of ventilation and alterations in arterial PCO2 in adjusting arterial pH.
In this Medmastery Clinical Guide article, learn how the carbon dioxide-bicarbonate system buffers the body’s pH.
