Pulse Pressure Calculator
Posted by Dinesh onPulse pressure is the difference between the systolic and diastolic pressure readings. It is measured in millimeters of mercury (mmHg). It represents the force that the heart generates each time it contracts. If resting blood pressure is (systolic-diastolic) 120-80 millimeters of mercury (mmHg), pulse pressure is 40.
Systolic and Diastolic Blood Pressure Chart
The following table is from the American Heart Association showing the categories of hypertension and applies to adults above 18 years old . In the UK, a reading above 140/90 mmHg is considered hypertension.
| Category | Systolic (mmHg) | Diastolic (mmHg) |
|---|---|---|
| Hypotension | <90 | <60 |
| Normal | 90 - 119 | 60 - 79 |
| Prehypertenson | 120 - 139 | 80 - 89 |
| Stage 1 hypertension | 140 - 159 | 90 - 99 |
| Stage 2 hypertension | 160 - 179 | 100 - 109 |
| Hypertensive crisis | ≥180 | ≥110 |
Blood Pressure Readings and Meaning
- 90 over 60 (90/60) or less: You may have low blood pressure.
- More than 90 over 60 (90/60) and less than 120 over 80 (120/80): Your blood pressure reading is ideal and healthy.
- More than 120 over 80 and less than 140 over 90 (120/80-140/90): You have a normal blood pressure reading but it is a little higher than it should be, and you should try to lower it.
- 140 over 90 (140/90) or higher (over a number of weeks): You may have high blood pressure (hypertension).

| Reading | Meaning |
|---|---|
| if your top number is 140 or more | You may have high blood pressure |
| if your bottom number is 90 or more | You may have high blood pressure |
| if your top number is 90 or less | You may have low blood pressure |
| if your bottom number is 60 or less | You may have low blood pressure |
Calculate Pulse Pressure
Formula:
Ppulse = Psys - Pdias
where,Psys = Systolic pressure
Pdias = Diastolic pressure
Ppulse = Pulse pressure
