Table 1.
Physiologic variables of the APACHE II score. The score considers the worst values in 12 parameters in the first 24 h, which were categorized and aggregated to create the Acute Physiology Score. The APACHE II score is obtained by adding the Age Points to the Acute Physiological Score. APACHE, Acute Physiology and Chronic Health Evaluation; MAP, mean arterial pressure; PaO2, partial pressure of oxygen; WBC, white blood cell; GCS, Glasgow Coma Scale.
