Introduction
The Clinical Dehydration Scale gives a quick, four-sign bedside score (0-8) to classify dehydration severity in children, guiding fluid-replacement decisions without needing lab tests.
How to use the Clinical Dehydration Scale (CDS) Calculator
- Score each of the four signs from 0 (normal) to 2 (clearly abnormal).
- Click Calculate to get the total score and severity classification.
- Use the radar chart to see which sign is driving the score.
Formula and Calculation Method
CDS score = Appearance + Eyes + Mucous membranes + Tears (each scored 0–2, total 0–8)
Visual breakdown
REFERENCE
0 = none · 1–4 = some dehydration · 5–8 = moderate/severe
Why use this calculator
A single composite number is easy to miscalculate under pressure. This tool totals the score instantly and visualises which specific sign is contributing most, helping teams communicate severity consistently.
FAQs
What does a score of 0 mean?
No clinically detectable dehydration.
What does 5–8 mean?
Moderate to severe dehydration — more aggressive fluid replacement and closer monitoring are typically warranted.
Is this validated for adults?
The CDS was developed and validated specifically for children; it is not intended for adult dehydration assessment.
