Description
Compare a recorded catheter-bag closing volume with a supplied balance.
Urinary records distinguish collected volume, collection duration, mean flow, anatomical side and the source of symptom codes. Millilitres, litres and cubic millimetres are volume units; dividing volume by a specified interval gives a mean rate. A diary transcription or volume balance needs verified collection and clinical context before it can inform care.
Compare a recorded catheter-bag closing volume with a supplied balance.
When to use this tool
Use Urinary Catheter Bag Change Balance when you already have openingMilliliters, addedMilliliters, emptiedMilliliters, recordedClosingMilliliters and need to compare a recorded catheter-bag closing volume with a supplied balance.
How to use the tool and how it works
- Enter openingMilliliters, addedMilliliters, emptiedMilliliters, recordedClosingMilliliters. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read expectedClosingMilliliters, discrepancyMilliliters. Use the output convention below.
Require four nonnegative mL quantities; expected closing=opening+added-emptied and discrepancy=recordedClosing-expectedClosing.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| openingMilliliters | Opening Milliliters | Required. Finite number; minimum 0. |
| addedMilliliters | Added Milliliters | Required. Finite number; minimum 0. |
| emptiedMilliliters | Emptied Milliliters | Required. Finite number; minimum 0. |
| recordedClosingMilliliters | Recorded Closing Milliliters | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| expectedClosingMilliliters | Expected Closing Milliliters | Required. Finite number. |
| discrepancyMilliliters | Recorded closing minus (opening+added-emptied), in mL. | Required. Finite number. |

}Limitations and assumptions
- Expected closing can be negative; the arithmetic does not establish physiological output, leakage, recording accuracy or a catheter-care action.
- 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 original collection log, measurement units and instrument protocol before interpreting a volume or flow. Use the full recorded trace for peak or time-varying flow; a mean or transcription is only one component of that record.
