PH
- Independent of the ABG selected, choose the worst pH from any of the blood gases.
- I see I have two different guides here. The above and also another from previous guide which collectors are following.
- Sending out a survey & will post clarification. TOstryzniuk 16:00, 12 February 2009 (CST)
| APACHE II - PH value | A | B |
| Instruction followed? | Use the PH from the worst ABG result you have selected for that patient? | Use the worst PH independant of the ABG you select? |

- When selecting a PH for your APACHE score do you:
- a. use the PH from the worst BLOOD GAS result you had selected for that patient
- -or-
- b. do select the worst PH which is independent of the ABG you used?TOstryzniuk 16:01, 12 February 2009 (CST)

- I use the worst pH of the same ABG, I do not extract another pH from another gas as that would be stacking the deck wouldn’t it? Basically I choose the gas that would score the highest for the apache as a lower/higher pH can sometimes count more than a lower p02. Feb 12.09

- Anyway, I look at the worst ph independant of the blood gas that I use. Jackie. Feb 12.09
