Blood Pressure Calculator
Classify a blood pressure reading and see pulse pressure and mean arterial pressure.
Inputs
Formula
- Pulse pressure = systolic − diastolic
- MAP = diastolic + (pulse pressure / 3)
Categories follow the widely used ACC/AHA bands. One high reading means little — measure seated, rested, at the same time on several days before drawing conclusions.
Step-by-step calculation

- 2
MAP
dia + PP/3
93 mmHg
