Silverman Anderson Score Calculator
Use the Silverman Anderson 0-10 table to grade neonatal respiratory distress from chest movement, retractions, nasal flaring, and grunting.
Clinical disclaimer
How the score works
The Silverman-Anderson score assigns 0-2 points across five domains. Total scores range from 0 to 10; higher scores indicate more severe respiratory distress.
- Upper chest movement and see-sawing describe thoracoabdominal synchrony.
- Lower chest and xiphoid retractions describe work of breathing.
- Nasal flaring and expiratory grunting signal increased respiratory effort.
Interpretation
- 0: no respiratory distress.
- 1-3: mild distress.
- 4-6: moderate distress.
- 7-10: severe distress; consider escalation of support.
Trend scores over time and reassess after interventions.
Clinical notes
- Prematurity, sedation, or fatigue may blunt visible retractions and grunting.
- Use the score with oxygen saturation, blood gases, and overall appearance.
- Scores are helpful for trending but do not replace clinician assessment.

Frequently asked questions
It grades neonatal respiratory distress by scoring chest movement, retractions, nasal flaring, and expiratory grunt. Higher scores indicate more severe distress.
Scores of 0 indicate no distress, 1-3 mild, 4-6 moderate, and 7-10 severe respiratory distress. Always follow local protocols.
Yes, but prematurity and sedation can affect the findings. Use clinical judgment and trend scores over time.
No. It is a structured bedside tool that should complement vital signs, oxygenation, and clinician assessment.
