如何计算Glasgow Coma

learn.whatIsHeading

The Glasgow Coma Scale quantifies consciousness level from 3 (minimum) to 15 (maximum). It's used in emergency medicine to assess neurological status and predict outcomes.

公式

Total GCS = E + V + M; results interpret consciousness level

GCS: E + V + M; results interpret consciousness level — E + V + M; results interpret consciousness level
E: E value — Variable used in the calculation
V: V value — Variable used in the calculation
M: M value — Variable used in the calculation

分步指南

1Score eye opening (E), verbal response (V), and motor response (M)
2Enter values from patient observation: E (1-4), V (1-5), M (1-6)
3Total GCS = E + V + M; results interpret consciousness level

例题解析

输入

E=3 (closed), V=1 (none), M=3 (abnormal flexion)

结果

GCS = 7 (severe impairment)

Indicates critical condition

常见错误注意事项

✕Misinterpreting pain response levels in motor component
✕Not accounting for intubation when recording verbal score

常见问题

What does each component measure?

Eye opening shows arousal; verbal response shows orientation; motor response shows ability to obey commands.

How does GCS predict outcome?

Lower GCS scores correlate with worse outcomes; GCS 3-5 has mortality ~80%, GCS 13-15 has mortality ~5%.
