Pulse Pressure accuracy and testing
This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.
Formula source
- PP = Systolic - Diastolic
Test cases
Default input regression check
Generated from the checked-in default inputs and calculate function.
Inputs
- Systolic (Top): 120 mmHg
- Diastolic (Bottom): 80 mmHg
Expected outputs
- Pulse Pressure: 40 mmHg
- Indication: Normal Range (~40)
Known limitations
- For educational purposes only. Single readings can vary significantly. Clinical decisions should not be based on this calculation alone.
Assumptions
- The output is based on one blood-pressure reading and may shift with repeat measurements.
- Pulse pressure is a descriptive marker and does not identify the cause of a wide or narrow pattern on its own.
- Interpretation depends on age, symptoms, medications, and the broader cardiovascular context.
Unit handling
- Systolic (Top) accepts values in mmHg.
- Diastolic (Bottom) accepts values in mmHg.
- Pulse Pressure is displayed in mmHg.
Rounding rules
- Number displays use up to 2 decimal places in the calculator UI.
