Description
Integrate one supplied research trace interval by an explicit trapezoid or left-held rule; no uroflow diagnosis.
A research diary or bench measurement uses a defined observation window, clock, unit, and reference level. Missing timing, incomplete collection, and unverified measurements affect how a result can be interpreted. Record arithmetic and signal terms describe supplied data without establishing clinical status.
Integrate one supplied research trace interval by an explicit trapezoid or left-held rule; no uroflow diagnosis.
When to use this tool
Use Uroflow Sample Volume Increment when you need a research-record or bench calculation with already supplied measurements, units, and observation boundaries.
How to use the tool and how it works
- Enter firstFlow, secondFlow, duration, trapezoid. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read volumeIncrement. Use the output convention below.
Multiply duration by firstFlow when trapezoid is false or by (firstFlow+secondFlow)/2 when true. Require nonnegative duration and return volumeIncrement.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| firstFlow | First Flow | Required. Finite number. |
| secondFlow | Second Flow | Required. Finite number. |
| duration | Duration | Required. Finite number; minimum 0. |
| trapezoid | Trapezoid | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| volumeIncrement | Volume Increment | Required. Finite number. |

}Limitations and assumptions
- Flow and duration units must be compatible. The rectangle branch ignores secondFlow in the arithmetic, and neither branch identifies artifacts, chooses sampling intervals, or interprets a clinical measurement.
- The field tables state structural bounds; the mechanics also specify cross-field constraints. Malformed inputs and unsupported domains cause errors. A successful false flag, empty branch value, or zero placeholder has the meaning stated above and is distinct from an input error.
- 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. Signed zero is exported as zero.
Alternative or Complementary methods
Use an appropriately validated measurement and analysis method for clinical interpretation. Verify diary completeness, clock conventions, and measurement units before combining these terms into a research summary.
