Use our advanced APACHE II Calculator to quickly determine the Acute Physiology and Chronic Health Evaluation II score. This powerful tool helps medical professionals assess disease severity and predict mortality in critically ill patients based on key physiological data, age, and chronic health status. Make informed clinical decisions with accurate scoring and timely insights.
Formula:
The APACHE II (Acute Physiology And Chronic Health Evaluation II) score is calculated as the sum of three components:
APACHE II Score = Acute Physiology Score (APS) + Age Score + Chronic Health Score
The Acute Physiology Score (APS) is derived from 12 physiological variables, with points assigned based on deviation from normal ranges (worst value in first 24 hours). The Age Score adds points based on the patient's age. The Chronic Health Score accounts for severe organ insufficiency or immunocompromised status, with points varying based on admission type.
