🚑 CPSS (Cincinnati Prehospital Stroke Scale)
UseWhen to use: rapid EMS/ED screen when FAST/CPSS is the local tool.
Strata≥1 abnormal = positive screen; more items → higher stroke probability.
LimitsWhen not to use: as in-hospital severity scoring (use NIHSS). · Pitfall: missing posterior-circulation presentations. · Pair with glucose and onset-time documentation.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Facial droop | Normal / absent |
|---|---|
| Arm drift | Normal / absent |
| Speech | Normal |
→CPSS positives0/3
- Screen：Negative — all items normal
| Facial droop | Abnormal (unilateral droop) |
|---|---|
| Arm drift | Abnormal (drift / falls) |
| Speech | Abnormal (slurred / wrong words / mute) |
→CPSS positives3/3
- Screen：Positive — ≥1 abnormal item

- Does CPSS (Cincinnati Prehospital Stroke Scale) upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is CPSS (Cincinnati Prehospital Stroke Scale) calculated in practice? Can you show a worked example?
- Inputs: Facial droop Normal / absent, Arm drift Normal / absent, Speech Normal → Result: CPSS positives 0 /3（Screen: Negative — all items normal） Inputs: Facial droop Abnormal (unilateral droop), Arm drift Abnormal (drift / falls), Speech Abnormal (slurred / wrong words / mute) → Result: CPSS positives 3 /3（Screen: Positive — ≥1 abnormal item）
