Cellulitis and erysipelas

National Early Warning Score 2 (NEWS2) is an early warning score produced by the Royal College of Physicians in the UK. It is based on the assessment of six individual parameters, which are assigned a score of between 0 and 3: respiratory rate, oxygen saturations, temperature, blood pressure, heart rate, and level of consciousness. There are different scales for oxygen saturation levels based on a patient’s physiological target (with scale 2 being used for patients at risk of hypercapnic respiratory failure). The score is then aggregated to give a final total score; the higher the score, the higher the risk of clinical deterioration
