What the result means
- Bands
- ADVISORY only — sources disagree on cut-points. Commonly cited: <=3 mild, middle moderate, >=9 severe. Higher = more severe.
What you enter
- Respiratory rate (breaths/min)
- Wheezing grade (0-3)
- Retraction grade (0-3)
- General condition (0 normal or 3 distressed)
How this is calculated
- Items
- respiratory rate (banded 0-3), wheezing (0-3), retraction (0-3), general condition (0 or 3 only) = 0-12.
