== Guidelines for the Values to use for APACHE II Physiologic Variables ==

*You can not enter 0 for any of these, and you can't leave them blank.

*The general rule is to use the WORST value in the initial 24 hours of the ICU record (remember that ICU records begin when the patient begins being cared for by the ICU service, not when he/she arrives in the ICU)

*The general rule is to use the WORST value in the initial 24 hours of the ICU record (remember that ICU records begin when the patient begins being cared for by the ICU service (i.e. [[Accept DtTm]] resp [[Service tmp entry]] dttm) , not when he/she arrives in the ICU (ie. [[Arrive DtTm]] resp [[Boarding Loc]]))

**What we mean by "worst" is as per APACHE II rules

*If for a given parameter there are NO values during that initial 24 hours after the start of the ICU record, you can go back ''prior'' to the start of the ICU record, and use the value closest to the start time of the ICU record (but max 24 hrs prior to admission).

**If there are no values for that parameter either during the first 24 hours OR up to 24 hours prior to the start of the ICU record, APACHE assumes the value was normal -- so code the value that is the midpoint of the normal range per APACHE rules.

*In regards to values that occurred or measured during cardiopulmonary arrests:

*In regards to values that occurred or measured during cardiopulmonary arrests (e.g. [[Cardiac arrest]]):

**'''DO NOT''' use vital signs from arrests

**You can use labs drawn during arrests, but only do so if these are the ONLY labs available.
