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.
The HCT contain's a patient's hematocrit value. We collect it for generating the APACHE score.
- Select the WORST deviation from normal during the first 24 hours in ICU.
- Hematocrit (HCT) is recorded as a percentage, e.g. 0.352 record as 35.2
