Understanding Your Results

Maintaining healthy blood pressure and a steady pulse rate is vital for long-term cardiovascular health. This calculator uses standard American Heart Association (AHA) guidelines to interpret your readings.

Category Systolic (mmHg) Diastolic (mmHg)
Normal Less than 120 Less than 80
Elevated 120 – 129 Less than 80
Hypertension Stage 1 130 – 139 80 – 89
Hypertension Stage 2 140 or higher 90 or higher
Hypertensive Crisis Higher than 180 Higher than 120

What is Pulse Pressure?

Pulse pressure is the difference between your systolic and diastolic blood pressure. For example, if your resting blood pressure is 120/80 mmHg, your pulse pressure is 40 mmHg. Generally, a pulse pressure greater than 60 mmHg is considered a risk factor for cardiovascular events, especially in older adults.

What is Mean Arterial Pressure (MAP)?

Mean Arterial Pressure represents the average pressure in a patient's arteries during one cardiac cycle. It is considered a better indicator of perfusion (blood flow) to vital organs than systolic blood pressure alone. A MAP between 70 and 100 mmHg is usually considered normal.

Heart Rate (Pulse) Guidelines

A normal resting heart rate for adults ranges from 60 to 100 beats per minute. However, a lower resting heart rate (40–60 BPM) often implies more efficient heart function and better cardiovascular fitness in athletes.

  • Bradycardia: Under 60 BPM (Resting)
  • Normal: 60 – 100 BPM
  • Tachycardia: Over 100 BPM (Resting)

Examples of Health Scenarios

Scenario A (Healthy Adult): A reading of 115/75 mmHg with a pulse of 65.
Result: Normal BP, Pulse Pressure of 40, MAP of 88. This indicates excellent cardiovascular health.

Scenario B (Stage 1 Hypertension): A reading of 135/85 mmHg with a pulse of 88.
Result: Stage 1 Hypertension. While the pulse is normal, the pressure suggests lifestyle changes or monitoring may be necessary.
