Pulse Pressure Calculator

Pulse pressure calculator finds the difference between systolic and diastolic blood pressure. A normal pulse pressure is around 40 mmHg, while values above 60 or below 25 mmHg may signal cardiovascular concerns.

Formula

#
Core Formula
PP=SBPDBP\text{PP} = \text{SBP} - \text{DBP}

How it works: Measures the force the heart generates each time it contracts. A wide pulse pressure can indicate arterial stiffness.

Worked Example

120/80 mmHg -> Pulse Pressure 40 mmHg.

Understanding Pulse Pressure

Pulse pressure is the numerical difference between your systolic (top number) and diastolic (bottom number) blood pressure readings. It reflects the force your heart generates with each contraction and the elasticity of your arteries.

  • Normal pulse pressure: approximately 40 mmHg (e.g., 120/80 = 40)
  • Wide pulse pressure (>60 mmHg): may indicate aortic regurgitation, hyperthyroidism, arterial stiffness, or aging
  • Narrow pulse pressure (<25 mmHg): may suggest heart failure, cardiac tamponade, aortic stenosis, or shock
  • Pulse pressure tends to increase with age due to arterial stiffening
  • Elevated pulse pressure is an independent risk factor for cardiovascular events

Pulse pressure is one component of a comprehensive cardiovascular assessment. This calculator is for educational purposes only and does not replace professional medical evaluation.

You can also calculate changes using our Mean Arterial Pressure (MAP) Calculator or Target Heart Rate Calculator.

Frequently Asked Questions

What is a normal pulse pressure?

A normal pulse pressure is typically around 40 mmHg. For example, a blood pressure reading of 120/80 mmHg gives a pulse pressure of 40.

What does a high (wide) pulse pressure mean?

Values consistently above 60 mmHg may indicate aortic regurgitation, hyperthyroidism, arterial stiffness, or advanced age. It is an independent cardiovascular risk factor.

What does a narrow pulse pressure mean?

A pulse pressure below 25 mmHg may indicate heart failure, aortic stenosis, cardiac tamponade, or hypovolemic shock. It suggests reduced stroke volume.

Why does pulse pressure increase with age?

As arteries stiffen with age (arteriosclerosis), they lose compliance. This causes systolic pressure to rise more than diastolic, widening the pulse pressure.

How is pulse pressure different from mean arterial pressure?

Pulse pressure (SBP minus DBP) measures the pulsatile force of each heartbeat. Mean arterial pressure (MAP) estimates the average pressure throughout the cardiac cycle and is calculated differently.

Should I use this calculator instead of seeing a doctor?

No. This tool is for educational purposes only. Abnormal pulse pressure readings should be evaluated by a qualified healthcare professional in the context of a full clinical assessment.
