Description
Measure a supplied ambulance arrival-to-handover interval.
Emergency records distinguish event clocks, retrospective entry times, equipment dates, encounter identifiers and recorded triage or laboratory states. A supplied time gap is not a verified performance measure, and a recorded seal expiry does not establish equipment readiness. Simulation duty fractions and role labels describe training records rather than emergency-care instructions.
Measure a supplied ambulance arrival-to-handover interval.
When to use this tool
Use Ambulance Hand Over Time Pair when you already have arrivalTimestampSeconds, handoverTimestampSeconds and need to measure a supplied ambulance arrival-to-handover interval.
How to use the tool and how it works
- Enter arrivalTimestampSeconds, handoverTimestampSeconds. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read handoverIntervalSeconds. Use the output convention below.
Require handoverTimestampSeconds>=arrivalTimestampSeconds; return handover-arrival in seconds.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| arrivalTimestampSeconds | Arrival Timestamp Seconds | Required. Finite number. |
| handoverTimestampSeconds | Handover Timestamp Seconds | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| handoverIntervalSeconds | Handover Interval Seconds | Required. Finite number. |
{
"input": {
"arrivalTimestampSeconds": 1000,
"handoverTimestampSeconds": 1600
},
"output": {
"handoverIntervalSeconds": 600
}
}Limitations and assumptions
- No midnight wrap, clock correction, actual handover, performance target or care adequacy is established.
- 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
Review the actual event, equipment and laboratory records with verified timing and the complete clinical workflow. Treat local flags and interval arithmetic as record checks; they do not supply triage, response protocols, safe staffing or an assessment of a real emergency.
