# RESCUE-IHCA ECPR Integer Score Calculator (Tonna 2022 Table 2)

> RESCUE-IHCA ECPR Integer Score Calculator (Tonna 2022 Table 2) is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Computes the Tonna 2022 RESCUE-IHCA Table 2 integer score for predicting in-hospital death after adult extracorporeal CPR (ECPR), based on age, renal status, time of arrest, illness category, presenting rhythm, and arrest duration.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability rescue-ihca-ecpr-integer-score-calculator-tonna-2022-table-2-7308319e
```

Example prompt: Calculate the RESCUE-IHCA ECPR score for a 58-year-old patient with preexisting renal insufficiency who had a medical cardiac arrest at 10pm, presented with ventricular fibrillation, and CPR lasted 35 minutes.

## When to prefer this

Use this endpoint when you need to compute the validated Tonna 2022 RESCUE-IHCA Table 2 integer score specifically for adult ECPR candidates in in-hospital cardiac arrest; prefer it over general mortality scoring tools when the clinical context is ECPR and the Tonna 2022 derivation cohort is appropriate.

## Known failure modes

- Missing required query parameters (age, preexisting_renal_insufficiency, time_of_day, illness_category, presenting_rhythm, duration_min) returns validation error
- Age outside 18-120 range may be rejected or produce out-of-range result
- Invalid enum values for time_of_day, illness_category, or presenting_rhythm return error
- Duration_min outside 0-180 may be rejected
- Payment failure or missing x402 payment header results in 402 response

## How this service works

Tonna 2022 RESCUE-IHCA Table 2 integer score for in-hospital death after adult ECPR. Age 2 + 2 per 10 years after 20. Renal +8. Time: day 0, evening +4, night +13. Illness: medical noncardiac 0, medical cardiac -2, surgical noncardiac -6, surgical cardiac -11. Rhythm: asystole 0, PEA -1, pVT -5, VF -8, palpable pulse -5. Duration +2 per 10 min. Table 2 min -17. Integer score only. Not an ECPR order.

## Output

Returns a single integer RESCUE-IHCA score (minimum -17) computed from Tonna 2022 Table 2 coefficients: age points (2 + 2 per decade after 20), renal insufficiency (+8), time of arrest (0/+4/+13), illness category (0/-2/-6/-11), presenting rhythm (0/-1/-5/-8/-5), and arrest duration (+2 per 10 minutes). The score is informational only and does not constitute a clinical order or recommendation.
