| *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?[[User:TOstryzniuk|TOstryzniuk]] 16:01, 12 February 2009 (CST)

| '''*NORINE-VIC'''
| |
| *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

| '''Jackie Winestock_VIC'''
| |
| *Anyway, I look at the worst ph independant of the blood gas that I use. Jackie. Feb 12.09

APACHE Score
This value is used to generate the APACHE Score.
Collecting Apache physiological variables
There are some specific rules to follow in choosing which one of several lab results to collect.
See APACHE physiological variable collection for details.
Cross Chcks
Rules described in APACHE_physiological_variable_collection#Exceptionally_high_or_low_values are implemented by Check APACHE physiological variable high low.
History
There have been different collection practices used when selecting the PH value, the original APACHE II user manual (version 1.0) is as above and that is how it should be collected.
