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
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.
- an ABG result is preferred, but if no ABG available during the first 24 hours in ICU then select the worst serum CO2
FiO2 ≤ 49% - Base your selection of the worst ABG on the worst PO2.
FiO2 ≥ 50% - Base your selection of the worst ABG on the worst AaDO2. AaDO2 Calculation: AaDO2 is the arterial-alveolar O2 tension difference) AaDO2 = (FiO2 X 713) - PO2 - CO2 e.g. (FiO2 0.5 X 713) - PO2 85- CO2 40 = AaDO2 231.5
- See APACHE Scoring table
- See FiO2 table
This element is also collected for:
- Labs test counts
