Including pulse oximetry as a component of an early warning score improves its ability to predict mortality following a cardiac arrest call or unplanned Intensive Care Unit admission

摘要

It is well recognised that ward-based early warning score systems can be used to predict outcome. In 2007 the UK's National Institute for Health and Clinical Excellence (NICE) recommended that physiological scoring systems should include the following variables: heart rate (HR), systolic blood pressure (BP), respiratory rate (RR), temperature (T), assessment of consciousness level (Alert, Verbal response, Pain response, Unresponsive - AVPU) and oxygen saturation (S_pO_2). Our aim was to assess several published scoring systems against our existing Modified Early Warning Score (MEWS) which includes HR, BP, T, RR, AVPU and urine output (UO).
