Description
Return event-gap bounds from supplied precision half-widths.
Anesthesia-related research and training records require explicit clocks, missingness flags, exclusions and measurement references. These tools reconcile benign records, simulations or bench data; an acceptable local overlap or composition sum does not establish clinical adequacy or safe patient care. Censored observations provide bounds rather than observed event times.
Return event-gap bounds from supplied precision half-widths.
When to use this tool
Use Anesthesia Study Event Precision Envelope when checking the stated benign record, simulation, timing or bench-measurement convention.
How to use the tool and how it works
- Enter firstTime, firstHalfwidth, secondTime, secondHalfwidth. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read minimumGap, maximumGap, definitelyOrdered. Inspect definitelyOrdered before interpreting the associated values.
Return event-gap bounds from supplied precision half-widths. Require nonnegative half-widths; minimumGap = second-first-uSecond-uFirst, maximumGap = second-first+uSecond+uFirst, definitelyOrdered requires strict positive minimum gap.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| firstTime | First Time | Required. Finite number. |
| firstHalfwidth | First Halfwidth | Required. Finite number; minimum 0. |
| secondTime | Second Time | Required. Finite number. |
| secondHalfwidth | Second Halfwidth | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| minimumGap | Second event’s earliest bound minus first event’s latest bound; strict positivity establishes definitelyOrdered. | Required. Finite number. |
| maximumGap | Maximum Gap | Required. Finite number. |
| definitelyOrdered | Definitely Ordered | Required. Boolean. |

}Limitations and assumptions
- Touching envelopes do not establish strict order; these are supplied precision bounds, not confidence intervals or clinical event verification.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use verified source records and appropriate complete analysis for research or quality review; seek qualified medical and engineering assessment for actual clinical care or equipment decisions.
