APACHE Scoring table

The Scoring table for APACHE II describes how various fields we collect affect the ultimate APACHE II score. The score itself is automatically calculated, no manual addition needs to be performed.

WBC	≥40		20-39.9	15-19.9	3-14.9		1-2.9		<1

Glasgow Coma Scale

For information on collecting and coding the values, see the Glasgow Coma Scale article.

A Glasgow Coma Scale score of 15 would be considered "Total Neuro Points".

The Glasgow Coma Scale is scored in APACHE II as follows:

Points	6	5	4	3	2	1
EYES			Spontaneous	To Speech	To Pain	None
MOTOR	Obeys Command	Localizes Pain	Withdraws to Pain	Abnormal Flexion	Abnormal Extension	None
VERBAL		Oriented	Confused	Inappropriate words	Incomprehensive sounds	None

Calculations

Mean Blood Pressure

Mean BP = ((2x Diastolic) + Systolic) ÷ 3

AaDO2 (for Fi02 >= 50 %)

AaDO2 = ((FiO2 * 713) - P02) - C02
