Carbon dioxide tension

Broader Terms

This means that tissue hypoxia, in the sense of utilisation of anaerobic metabolism, occurs at a tissue oxygen tension which is lower the lower the arterial carbon dioxide tension is.
The clinical significance of this increase in arterial carbon dioxide tension is discussed.
To overcome this difficulty, the arterial carbon dioxide tension is used as an inversely proportional index of `effective' alveolar ventilation.
Thus the rate at which oxygen is given up to the tissues is increased when the carbon dioxide tension is raised.
In the tissues of the body, where oxygen tension is low and carbon dioxide tension is high, oxyhemoglobin liberates its oxygen in exchange for carbon dioxide.
