⚠️

TESTING VERSION - NOT FOR CLINICAL USE
This tool is currently for testing purposes only and should not be used for clinical decision-making.

For medical professionals only. This tool provides guidance and is not a substitute for clinical judgment. Reassess patients regularly and adjust fluid regimens as needed.

Is your patient older than 1 month old?

Patient Age

Years

Months 0–11

Weight (kg)

Maintenance fluid rate exceeds typical maximum. Please re-check weight input.

Dehydration Percentage

Is the patient in shock?

Are there ongoing losses?

Clinical Assessment: Classify dehydration based on the presence of clinical signs. Two or more signs in a category indicate that level of severity.

Clinical Signs	Mild < 5% fluid loss	Moderate 5–10% fluid loss (≥ 2 signs)	Severe > 10% fluid loss (≥ 2 signs)
General Condition	Well, alert	Restless / irritable	Lethargic / unconscious
Eyes	Normal	Sunken	Deeply sunken
Thirst	Normal drinking	Drinks eagerly / thirsty	Unable to drink / drinks poorly
Skin Pinch	Immediate	Slow	Very slow (> 2 sec)
