Child Growth Velocity Calculator
Calculates how fast a child is growing in centimeters per year using two height measurements taken over a known time period.
Pediatric Fever Management Calculator
Checks whether a child's temperature calls for fever medicine, whether enough time has passed since the last dose, and what the next weight-based dose of acetaminophen or ibuprofen is.
Pediatric Fever Assessment Calculator
Scores fever severity in children by combining temperature, age, fever duration, and accompanying symptoms into a single risk index.
Child Daily Hydration Calculator
Estimates a child's daily fluid needs in milliliters based on weight, activity level, climate, and illness.
Infant Feeding Volume Calculator
Estimates the recommended daily milk or formula volume for healthy term infants using the 150 mL/kg/day guideline.
Pediatric Fluid Requirements Calculator
Calculates a child's daily fluid requirement in milliliters using the Holliday-Segar method, adjusted for activity level and clinical conditions like fever or dehydration.
