Case contract

Input {age_months, hr, rr, behavior, crt_s, o2_lpm}. Toy normal ranges by age: < 12 months HR 100-160 RR 30-50; 12-47 HR 90-150 RR 24-40; 48-143 HR 70-120 RR 18-30; >= 144 HR 60-100 RR 12-20. Deviation = distance outside the range (0 inside). Cardiovascular: 2 if HR deviation > 20 or refill >= 4 s, 1 if any HR deviation or refill 3 s, else 0. Respiratory: 2 if RR deviation > 10 or oxygen >= 4 L/min, 1 if any RR deviation or any oxygen, else 0. Behaviour: playing/sleeping 0, irritable 1, lethargic 3. escalate when total >= 5 or behaviour scores 3. Return {score, escalate}.

Why this case matters

Paediatric warning scores depend on the right age band and on two-sided deviation from normal ranges.

One recorded failure
