Introduction

Background

    A component of the APACHE II classification system , the Acute Physiology Score (APS) measures the physiological condition of the critically ill patients in intensive care units. The APACHE II Acute Physiology Score scale ranges from 0, least deranged/severe, to 60, most deranged/ severe and is based on 12 clinical measures (Temperature, Mean Arterial Pressure, Heart Rate, Respiratory Rate, Oxygenation, Arterial ph, Serum Sodium, Serum Potassium, Serum Creatinine, Hematocrit, White Cell Count, and Glasgow Coma Scale) made during the initial 24 hours in the ICU.
