x402
Magent Shock Index Calculator 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 Allgöwer-Burri shock index as heart rate divided by systolic blood pressure, returning the ratio rounded to two decimals.

How this service works
Shock index as heart rate in bpm divided by cuff systolic pressure in mm Hg (Allgöwer and Burri 1967). Returns the original ratio rounded to two decimals. Not a shock diagnosis, treatment target, or cutoff, and does not use MAP or diastolic pressure.
Output
Returns the shock index as a numeric ratio (heart rate in bpm divided by systolic blood pressure in mmHg) rounded to two decimal places. This is the original Allgöwer-Burri (1967) formula value only — not a diagnosis, not a treatment target, and not a threshold-based interpretation.
Example use cases
Emergency triage vital sign ratio
“My patient in the ED has a heart rate of 125 bpm and a systolic BP of 90 mmHg — what's their shock index?”
Automated EHR vitals pipeline
“For the incoming trauma patient with HR 102 and cuff systolic of 110, compute the Allgöwer shock index so I can flag it in the chart.”
Postpartum hemorrhage monitoring
“Can you run the shock index for a postpartum patient with a pulse of 95 bpm and a systolic reading of 100 mmHg?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/shock_indexWhen to prefer
Choose this endpoint when you need a fast, reproducible, formula-exact implementation of the classic Allgöwer-Burri (1967) shock index — HR/systolic BP — without any interpretation layer. Prefer it when building clinical decision support pipelines that require the raw ratio (not MAP-based or diastolic variants) for downstream logic, audit trails, or documentation. It is the right choice when you need the original published formula specifically, not a modified shock index variant.
Side effects
- Heart rate outside 30–220 bpm range returns a validation error
- Systolic pressure outside 50–250 mmHg range returns a validation error
- Missing required query parameters (heart_rate_bpm or systolic_mm_hg) returns an error
- Non-integer heart_rate_bpm causes a schema validation failure
- Division by zero not possible given minimum systolic constraint of 50 mmHg
