Fluid overload in percent in the intensive care unit
Cumulative balance since admission in % of admission weight: (intake − output in litres) ÷ kg × 100 – without fixed thresholds
Calculation aid for healthcare professionals: the calculator reproduces what the sources cited assign to the inputs. Clinical assessment and every treatment decision remain with the treating physician. Inputs and results are not stored.
Frequently asked questions
Fluid overload in percent in the intensive care unit: What does this calculator compute?
Calculates the fluid overload of a child in intensive care: sum of intake minus sum of output since admission in liters, divided by the admission weight in kg, times 100 (formula according to Goldstein 2001 as in the Pediatric ADQI consensus 2024). With reservations: there is no fixed threshold for harmful overload; the calculator only shows the percentage and the level in the Renal Angina Index.
