| Select the '''worst deviation from normal''' Arterial Blood Gases (ABG) as outlined on the APACHE II scoring table. '''Do not use venous gases.'''
| | == No ABG Available Rule, see [[serum CO2]]===\ |
| | |
| FiO<sub>2</sub> ≤ 49% - Base your selection of the '''worst''' ABG on the '''worst''' PO2.
| |
| | |
| FiO<sub>2</sub> ≥ 50% - Base your selection of the '''worst''' ABG on the '''worst''' AaDO2.
| |
| AaDO<sub>2</sub> Calculation:
| |
| (AsDO<sub>2</sub> is the arterial-alveolar O<sub>2</sub> tension difference)
| |
| AaDO<sub>2</sub> = (Fi02 X 713) - PO<sub>2</sub> - CO<sub>2</sub>
| |
| e.g. (FiO<sub>2</sub> 0.5 X 713) - PO<sub>2</sub> 85-CO<sub>2</sub> 40 = AaDO<sub>2</sub> 231.5
| |
| | |
| *Clarification: For the FiO2, AaDO2/pO2 use the worst blood gas determination but a single full blood gas must be used for this. (not each value done independently).--[[User:LKolesar|LKolesar]] 13:25, 12 February 2009 (CST)

| === No ABG Available Rule ===
| |
| If no ABG is available during the first 24 hours in unit use the '''worst''' serum CO<sub>2</sub> value.
| |
|
| |
| === No ABG and no Serum CO<sub>2</sub> available ===
| |
| Assume normal, record serum CO<sub>2</sub> as '''25.0'''
