Modified early warning score
From Wikipedia, the free encyclopedia
Modified early warning score (MEWS) is a simple guide used by emergency medical services to quickly determine the risk of death of a subject. It is based on data derived from four physiological readings (systolic blood pressure, heart rate, respiratory rate, body temperature) and one observation (level of consciousness, AVPU). The resulting observations are compared to a normal range to generate a single score as follows:A score of five or more is clearly linked to increased likelihood of death and admission to a intensive care unit.
