x402
NICE CG174 Adult IV Maintenance Fluid Calculator is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).
Calculates adult hospital routine IV maintenance fluid requirements per NICE guideline CG174, returning daily volumes of water, sodium, potassium, chloride, and glucose based on dosing weight and a chosen ml/kg/day rate.

How this service works
NICE CG174 adult hospital routine maintenance: 20, 25, or 30 mL/kg/day water times dosing weight, about 1 mmol/kg/day sodium, potassium, and chloride each, and 50–100 g/day glucose. Flags water over 2.5 L without capping. Not 4-2-1, not Holliday–Segar, not a fluid-type order. Caller assigns IBW when obese. Deterministic published arithmetic with citation.
Output
Returns computed daily totals: water in mL (and a flag if it exceeds 2.5 L), sodium in mmol, potassium in mmol, chloride in mmol, and glucose in grams, all derived from the published NICE CG174 arithmetic for the supplied dosing weight and ml/kg/day rate.
Example use cases
Ward fluid prescription for standard adult
“My patient weighs 80 kg and I need the standard NICE CG174 routine maintenance fluids at 25 mL/kg/day — give me the daily water, sodium, potassium, chloride, and glucose targets, and flag if water goes over 2.5 L.”
Reduced maintenance for fluid-restricted patient
“I have a patient at risk of fluid overload — their dosing weight is 65 kg. Run the NICE CG174 reduced initial maintenance at 20 mL/kg/day so I can see how much water, sodium, potassium, and chloride they should get.”
Maintenance fluids for obese patient using IBW
“My patient is obese; I've already worked out their ideal body weight is 60 kg. Can you calculate NICE CG174 adult routine maintenance at 30 mL/kg/day using 60 kg and tell me the daily fluid and electrolyte targets?”

Endpoint
GEThttps://api.magentlab.com/api/calc/nice_iv_maintenanceWhen to prefer
Use this endpoint when you need deterministic, citation-backed NICE CG174 routine adult IV maintenance fluid calculations for a single patient — particularly when you want sodium/potassium/chloride/glucose targets alongside water volume, or when you need the 2.5 L water flag. Prefer it over generic fluid calculators when NICE guideline compliance matters, or when dealing with an obese patient where you have already assigned an ideal body weight. It is not appropriate for paediatric (4-2-1 or Holliday–Segar) calculations or for selecting fluid type/product.
Side effects
- Missing required ml_per_kg_day parameter returns validation error
- ml_per_kg_day value other than 20, 25, or 30 is rejected
- Weight outside the accepted range (1–500 kg or 2–1100 lb) returns an error
- Neither weight_kg nor weight_lb provided causes a missing-parameter error
- Payment not supplied or insufficient USDC results in 402 response
