Serum CO2: Difference between revisions

Revision as of 22:24, 2017 January 3

The Serum CO2 field contains a patient's Serum carbon dioxide level.

We collect it for generating the APACHE score.

an ABG result is preferred, but if no ABG available during the first 24 hours in ICU then select the worst serum CO2. (NOTE: for APACHE II scoring: the serum CO2 replaces PH and assumes normal oxygenation). Do not use venous gases.

IF no ABG & no serum CO2 available assume normal and record serum CO2 as 25.0.

NOTE: Serum CO2 is really a measure of serum HCO3-, also called bicarbonate. The procedure used to measure HCO3- in the laboratory first converts it to CO2. In the body, 95% of the CO2 is present as HCO3-, so most of what is measured in the laboratory represents HCO3-.TOstryzniuk 15:42, 25 May 2009 (CDT)
