Formula Used

Average Systolic = (S1 + S2 + S3) / 3

Average Diastolic = (D1 + D2 + D3) / 3

Pulse Pressure = Average Systolic − Average Diastolic

Mean Arterial Pressure = Average Diastolic + (Pulse Pressure / 3)

BMI = Weight in kg / (Height in m × Height in m)

Blood pressure categories here follow common clinical thresholds: normal is below 120/80, elevated is 120–129 with diastolic below 80, stage 1 starts at 130 systolic or 80 diastolic, stage 2 starts at 140 systolic or 90 diastolic, and crisis is above 180 or 120.

How to Use This Calculator

  1. Rest quietly for several minutes before checking your blood pressure.
  2. Enter three systolic and three diastolic readings in the form.
  3. Add heart rate, posture, arm used, and profile details if desired.
  4. Submit the form to display the result summary above the form.
  5. Review average values, category, pulse pressure, and mean arterial pressure.
  6. Use the graph to compare readings and the average level.
  7. Export the summary using the CSV or PDF buttons.
  8. Discuss repeated abnormal readings with a qualified clinician.

Frequently Asked Questions

1. What does this checker calculate?

It averages three readings, classifies the result, estimates pulse pressure and mean arterial pressure, and displays warnings that may deserve follow-up.

2. Why use three readings instead of one?

Multiple readings reduce random variation. Averaging them often gives a more stable picture than relying on a single measurement.

3. What is pulse pressure?

Pulse pressure is the difference between systolic and diastolic pressure. It can add useful context when monitoring circulation and arterial stiffness trends.

4. What is mean arterial pressure?

Mean arterial pressure is an estimate of average pressure through a cardiac cycle. It is commonly approximated as diastolic pressure plus one-third of pulse pressure.

5. Is this tool enough for a diagnosis?

No. It is a tracking and education tool. Diagnosis needs proper technique, repeated measurements, medical history, and professional interpretation.

6. When should I repeat a reading?

Repeat a reading after sitting quietly, with feet flat and arm supported. Avoid measuring immediately after exercise, stress, caffeine, or smoking.

7. What if the result says crisis?

Recheck carefully. If the reading remains above 180 systolic or 120 diastolic, especially with symptoms, seek urgent medical help promptly.

8. Can I save or print my result?

Yes. Use the built-in CSV export for spreadsheet records or the PDF export for a printable summary report.
