Description
Calculate breath reference zero gap from explicit caller-supplied inputs.
A bench or research calculation starts from supplied measurements, reference values, and unit conventions. A transformed value, timing difference, or support fraction describes that model; its clinical meaning depends on measurement validity and a separate professional assessment.
Calculate breath reference zero gap from explicit caller-supplied inputs.
When to use this tool
Use it for breath reference zero gap when the required inputs and conventions are already available.
How to use the tool and how it works
- Enter inspirationZero, expirationZero, suppliedCommonZero. Use the stated units and boundary conventions.
- Run the calculation. Correct any input error before interpreting a result.
- Read inspirationOffset, expirationOffset, zeroDifference. Inspect any known, defined, inclusion, or boundary flags before interpreting numeric values.
Subtract suppliedCommonZero from inspirationZero and expirationZero for their respective offsets, and return zeroDifference=expirationZero-inspirationZero.1

| suppliedCommonZero | Supplied Common Zero | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| inspirationOffset | Inspiration Offset | Required. Finite number. |
| expirationOffset | Expiration Offset | Required. Finite number. |
| zeroDifference | Zero Difference | Required. Finite number. |

}Limitations and assumptions
- These are supplied reference differences in a common unit. The tool does not find a baseline, align respiratory signals, or decide whether the difference is clinically significant.
- The field tables describe structural bounds; the mechanics also state cross-field requirements. Malformed input shapes, disallowed keys, and invalid domains cause input errors. Results must remain finite and within the declared output contract. A successful false flag or zero placeholder is distinct from an error.
- Numeric arithmetic uses binary floating point. Exact comparisons have no hidden tolerance or decimal rounding; negative zero is exported as zero. Decimal-text integer operations retain the exactness specifically stated above.
Alternative or Complementary methods
For breath reference zero gap, check the source records and the supplied rule before comparing the result with another method. Use an appropriately validated measurement or analysis method for clinical interpretation.
