Blood Pressure Classification Calculator

Blood Pressure Categories:

  • Normal: Systolic lower than 120 mmHg AND Diastolic lower than 80 mmHg
  • Elevated: Systolic 120-129 mmHg AND Diastolic lower than 80 mmHg
  • Stage 1: Systolic 130-139 mmHg OR Diastolic 80-89 mmHg
  • Stage 2: Systolic 140+ mmHg OR Diastolic 90+ mmHg

1. What is Blood Pressure Classification?

Blood pressure classification categorizes blood pressure readings into different groups based on systolic (upper) and diastolic (lower) values. These classifications help identify potential health risks and guide treatment decisions.

2. How Does the Calculator Work?

The calculator uses the following classification criteria:

  • Normal: Systolic lower than 120 mmHg AND Diastolic lower than 80 mmHg
  • Elevated: Systolic between 120-129 mmHg AND Diastolic lower than 80 mmHg
  • Stage 1: Systolic between 130-139 mmHg OR Diastolic between 80-89 mmHg
  • Stage 2: Systolic 140+ mmHg OR Diastolic 90+ mmHg

3. Importance of BP Classification

Details: Proper classification helps identify hypertension early, assess cardiovascular risk, and determine when lifestyle changes or medical treatment are needed.

4. Using the Calculator

Tips: Enter your systolic (upper) and diastolic (lower) blood pressure values in mmHg. The calculator will determine your classification based on current guidelines.

5. Frequently Asked Questions (FAQ)

Q1: What are normal BP limits?
A: Normal blood pressure has systolic lower than 120 mmHg and diastolic lower than 80 mmHg.

Q2: How often should I check my BP?
A: Adults should have BP checked at least annually. More frequent monitoring may be needed if values are elevated.

Q3: When is BP measurement most accurate?
A: Morning measurements after waking but before medication/coffee are often most representative.

Q4: Are there limitations to this classification?
A: Yes, classification should be based on multiple readings over time, not a single measurement.

Q5: What if my systolic and diastolic fall in different categories?
A: The higher category determines your overall classification.
