Methodology
Pulse pressure
PP = SBP − DBP
Pulse pressure reflects the stiffness of the large arteries and the volume of blood pumped with each beat. It tends to widen with age.
- Who it is for
- Adults with a measured blood pressure.
- Version
- 1.0.0
Worked example: how to calculate pulse pressure
Inputs
- Systolic blood pressure (top number)
- 120 mmHg
- Diastolic blood pressure (bottom number)
- 80 mmHg
Result
- Pulse pressure
- 40 mmHg
Within the usual range
Calculation:
120 − 80 = 40
An illustration with sample values, worked out with the same method the tool above uses.
Limitations
- Thresholds are descriptive; interpretation depends on the clinical context.
