Bedside PEWS (Pediatric Early Warning Score)
Calculate the Bedside Pediatric Early Warning System score using age-based vital signs and exam findings.
Last reviewed: February 26, 2026
Clinical disclaimer
Age bands follow completed months. A 3-month-old uses the 3-11 month band.
How Bedside PEWS works
Bedside PEWS sums seven parameters for a total score ranging from 0 to 26. Higher scores and rising trends correlate with increased risk of deterioration.
- Age-adjusted vital sign scoring for heart rate, systolic BP, and respiratory rate.
- Oxygenation scoring uses both SpO2 and the level of oxygen therapy.
- Respiratory effort and capillary refill capture clinical exam findings.
Age bands used
- 0-3 months
- 3-11 months
- 1-4 years
- 5-11 years
- 12+ years
Use completed months to select the band. At 12 years, use the 12+ band.
Scoring components
- Heart rate (age-adjusted)
- Systolic blood pressure (age-adjusted)
- Respiratory rate (age-adjusted)
- Oxygen saturation
- Oxygen therapy requirement
- Respiratory effort
- Capillary refill time
Interpreting scores
- Use the total score and any single high-risk parameter to determine escalation urgency.
- Trends matter. Rising scores over serial assessments warrant prompt review.
- Thresholds and actions vary by institution. Follow your local PEWS protocol.
Reassessment cadence
- Any elevated or rising score: repeat focused assessment promptly per local escalation pathway.
- After intervention (oxygen change, fluid, airway support): repeat score in the same clinical window.
- Stable low-risk trajectory: continue routine interval scoring with trend documentation.
Escalation triggers
- Rising serial PEWS despite initial interventions.
- High-risk single parameter (severe respiratory effort, hypotension, marked hypoxemia).
- Clinical deterioration that appears disproportionate to total score.
- Concern for sepsis, airway compromise, or evolving shock.
Shift handoff checklist
- Current total score plus parameter-level drivers of risk.
- Trend across recent assessments and intervals between scores.
- Interventions performed and observed response.
- Next reassessment time and explicit escalation threshold.
Compare with
- Modified PEWS calculator: use when your local pathway uses age-band cards instead of the Bedside PEWS structure.
- Pediatric vital signs chart: use when you need age-based ranges before deciding whether a score is abnormal.
- Pediatric Glasgow Coma Scale: use when neurologic status is the main deterioration signal.

Frequently asked questions
Bedside PEWS (BPEWS) is a pediatric early warning score that sums seven age-based physiologic and exam parameters to flag clinical deterioration risk.
The scoring table includes age bands for 0-3 months, 3-11 months, 1-4 years, 5-11 years, and 12+ years.
SpO2 points are assigned from the measured saturation, and oxygen therapy is scored separately (room air, low-flow, or high-flow). Use local guidance if oxygen can be safely weaned for assessment.
No. BPEWS is a decision-support tool meant to standardize assessment and trend changes over time. Escalation thresholds vary by institution.
Document total score, component drivers, trend direction, interventions, and next trigger for escalation. This preserves continuity and reduces missed deterioration.
