如何计算S O F A Score
learn.whatIsHeading
SOFA score assesses organ dysfunction in suspected sepsis. Sequential SOFA tracking identifies deterioration earlier than traditional markers.
分步指南
- 1Score six organ systems: respiration, coagulation, liver, cardiovascular, CNS, renal
- 2Each 0-4 points; total 0-24
- 3Score ≥2 from infection suspected indicates high mortality risk
例题解析
输入
Respiratory failure (PaO2/FiO2 200), platelets 90k, lactate elevated, confused
结果
SOFA = 9 (significant dysfunction)
Sepsis with organ dysfunction
常见错误注意事项
- ✕Using baseline SOFA alone instead of trending changes
- ✕Applying complex scoring in non-sepsis patients
常见问题
How does SOFA differ from APACHE?
SOFA focuses on organ dysfunction; APACHE is overall severity. SOFA better tracks sepsis progression.
What SOFA increase is clinically significant?
An increase of 2+ points from baseline in suspected infection increases mortality prediction substantially.
