ABGs are also collected in labs, see Lab Collection Process

ABG stands for Arterial Blood Gas (ABG).

ABG for APACHE II

All arterial blood gas results (FiO2, PO2, CO2 & PH) should be obtain from the SAME SPECIMEN.TOstryzniuk 20:57, 5 March 2009

• An ABG result is preferred, but if no ABG available during the first 24 hours in ICU then select the worst serum CO2

Select the worst deviation from normal Arterial Blood Gases (ABG) in the first 24 hours of ICU admission as outlined on the APACHE Scoring table. Do not use venous gases.

IF FiO2 ≤ 49% - Base the selection of the worst ABG on the worst PO2.

IF FiO2 ≥ 50% - Base the selection of the worst ABG on the worst AaDO2 (you can use the ABG Helper button to help determine this.

ABG Helper

There is an ABG helper in the CCMDB.mdb. You can enter two or more blood gas values and the program will show the number of apache points each value generates, whether it is the pO2, aADO2 or the ph. Choose the individual blood gas that gives the most apache points. Only one complete blood gas can be used (Do not pick a pH from one blood gas and other values from another blood gas).
