SIPA Score Calculator
Shock Index, Pediatric Age-Adjusted. Calculates HR ÷ SBP and compares the result with age-based pediatric thresholds used in trauma risk stratification.
For education and clinical decision support only. SIPA should not replace clinical judgment, full trauma assessment, or local protocols. Classic blunt-trauma calculator use is commonly limited to children aged 4–16 years; this tool displays the commonly published 1–16 year threshold table and flags ages outside 4–16.
Result
| Age group | SIPA cutoff | Interpretation |
|---|---|---|
| 1–6 years | > 1.2 | Elevated SIPA |
| 7–12 years | > 1.0 | Elevated SIPA |
| 13–16 years | > 0.9 | Elevated SIPA |
