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.

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.
