APACHE II evaluates various clinical factors to derive a score that reflects the severity of a patient's condition. These factors include:
Acute physiological parameters like body temperature, mean arterial pressure, heart rate, respiratory rate, arterial pH, serum sodium, potassium levels, creatinine, hematocrit, white blood cell count, and Glasgow Coma Scale (GCS). Age of the patient. Chronic health conditions such as liver cirrhosis, immunocompromised states, and chronic organ insufficiency.
