APACHE II

APACHE II (Acute Physiology and Chronic Health Evaluation II) is a scoring system used by medical professionals to assess the severity of illness and predict the risk of death in critically ill patients. It considers various factors like vital signs, lab results, and medical history taken within the first 24 hours of ICU admission. The score helps doctors understand how sick a patient is and guides treatment decisions. Higher scores indicate more severe illness and a greater risk of mortality, assisting in resource allocation and prognosis estimation.
