PCO2

From Wikipedia, the free encyclopedia

This is an old revision of this page, as edited by Quercus solaris (talk | contribs) at 12:59, 8 April 2016 (Cap P is the more common symbol. Also, P can be followed by any of several modifiers, such as "a" for arterial and "A" for alveolar, so the description of PCO2 and PaCO2 as merely synonymous was misleading. True that most mentions of PCO2 refer to PaCO2.). The present address (URL) is a permanent link to this revision, which may differ significantly from the current revision.

Carbon dioxide molecule.

The PCO2 is the partial pressure of carbon dioxide (CO2) in the blood. Usually the arterial blood is the relevant context; the symbol for PCO2 in arterial blood is PaCO2. Measurement of PaCO2 in the systemic circulation indicates the effectiveness of ventilation at the lungs' alveoli, given the diffusing capacity of the gas. It is a good indicator of respiratory function and the closely related factor of acid–base homeostasis, reflecting the amount of acid in the blood (without lactic acid).
