Six admission variables.
When to use
When to use: triage discussions for hypothermic CA considered for ECLS.
How it works
logit = 2.44 − 1.55·male − 1.95·asphyxia − 0.0191·age − 2.07·log₂(K⁺) − 0.573·log₂(CPR) + 0.937·T − 0.0247·T².
Key points
- Six admission variables.
- Log₂ K⁺ and CPR.
- Next: ECLS center / ERC hypothermia guidance.

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.
| Age | 45 years |
|---|---|
| Sex | Female (0) |
| Asphyxia-related mechanism (head submerged / avalanche asphyxia) | No |
| Serum potassium | 4.5 mmol/L |
| CPR duration to ECLS | 60 min |
| Core temperature | 24 °C |
→HOPE survival87.7%
- Logit score：1.965
- Cue：>30% — higher estimated survival with ECLS rewarming
| Age | 45 years |

FAQ
Frequently asked questions
- Does HOPE Score (Hypothermia ECLS Outcome) 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 HOPE Score (Hypothermia ECLS Outcome) calculated in practice? Can you show a worked example?
- Inputs: Age 45 years, Sex Female (0), Asphyxia-related mechanism (head submerged / avalanche asphyxia) No, Serum potassium 4.5 mmol/L, CPR duration to ECLS 60 min, Core temperature 24 °C → Result: HOPE survival 87.7 %（Logit score: 1.965, Cue: >30% — higher estimated survival with ECLS rewarming） Inputs: Age 45 years, Sex Male (+logit penalty), Asphyxia-related mechanism (head submerged / avalanche asphyxia) Yes, Serum potassium 4.5 mmol/L, CPR duration to ECLS 60 min, Core temperature 24 °C → Result: HOPE survival 17.7 %（Logit score: -1.535, Cue: 10–30% — intermediate estimated survival）
