Intensive care and infectious diseases
Also known as: NEWS2 (National Early Warning Score 2) · NEWS2 erken uyarı skoru
What it is for
NEWS2 scores six physiological parameters (0-3 points each) plus 2 points for supplemental oxygen; the sum (0-20) grades the clinical risk of acutely ill adults. Points:
