Five-level emergency acuity assignment: saturation danger threshold · case 05

A saturation of exactly 92% upgrades the patient.

Member previewVariant 5 · 3 implementations · 10 checks per implementation

Case contract

Input {lifesaving, high_risk, confused, pain (0-10), resources, age_years, hr, rr, spo2}. Toy algorithm: lifesaving intervention -> 1; high risk, confusion or pain >= 7 -> 2; otherwise resources 0 -> 5, 1 -> 4, >= 2 -> 3, except that patients needing >= 2 resources with danger-zone vitals are upgraded to 2. Danger zone: spo2 < 92 or hr/rr above age limits (age < 1: 180/50; 1-2: 160/40; 3-7: 140/30; 8+: 100/20). Return {level, upgraded}.

Why this case matters

Acuity algorithms are ordered decision trees with age-dependent vital limits; each branch condition is a separate defect site.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
