Fried's Rule Infant Dose Calculator
Bounded off line reference: HistoricalFriedrule reference only; obsolete simplistic extrapolation is not automated clinical dosing. Explicit topics historical formula, clinical limitation. No full/live authority, clinical diagnosis, safe-use approval or universal individual outcome.
Description
Fried's rule is a historical infant-age method that scales an adult dose using age in months.
Fried's rule is a historical infant-age method that scales an adult dose using age in months.1
This tool returns educational reference text and limitations, rather than calculating an infant's dose.
When to use Fried's Rule Infant Dose Calculator
Read a bounded educational reference for one of the supported topics.
How to use Fried's Rule Infant Dose Calculator and how it works
- Choose a supported exact topic from the table below.
- Enter that topic token and run the tool.
- Read result.text and its scope or precision limitations.
- Correct an unsupported token before rerunning; use an independently applicable reference when more detail or current evidence is required.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| topic | Topic. Use the units and matching context stated in the calculation below. | string | Required; other constraints below |
Choose one exact case-sensitive topic: historicalFormula, clinicalLimitation. The implementation matches that token to a stored text record and returns result.text unchanged. Unknown tokens, blank strings and wrong input types are errors; no case folding or live lookup occurs. These are bounded educational records, not a calculation from observations, a proof search, a patient assessment or an arbitrary-precision value. The supported topic inventory below identifies the available records.
text=storedInventory[exactTopic] Apply the input ordering, units and branch conditions stated above.
| Exact topic token | Record selected |
|---|---|
| historicalFormula | Stored historical formula reference. |
| clinicalLimitation | Stored clinical limitation reference. |
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the calculated or selected fields below. | object |
| result.text | Exact stored educational record selected by the supported topic token. | string |
{
"input": {
"topic": "historicalFormula"
},
"output": {
"result": {
"text": "Fried historical fraction: age months/150×adult dose. Historical arithmetic is not a current validated pediatric prescription."
}
}
}Limitations and assumptions
Patient context, drug formulation, route, sampling time, assay units and applicable clinician-verified protocol must be independently established. The output supplies no dosing, titration, switching or administration instruction.
This is a stored text inventory. It does not calculate from measurements, obtain live data, prove an infinite assertion, classify a patient or certify arbitrary precision.
All fields require explicit values. Unexpected fields, wrong types, nonfinite numbers and sparse arrays are rejected. Alignment, bounds and supported-token rules are explained above; extremely large inputs or nonfinite results can also fail. Input errors differ from successful false comparisons, unavailable-domain flags and empty match lists.
