1. What is Blood Pressure Ratio?

The blood pressure ratio (SBP/DBP) is a simple calculation that compares systolic to diastolic blood pressure. While not a diagnostic tool itself, it can provide additional insight into cardiovascular health when interpreted alongside absolute BP values.

2. How Does the Calculator Work?

The calculator uses the simple equation:

Where:

• \( SBP \) — Systolic blood pressure (mmHg)
• \( DBP \) — Diastolic blood pressure (mmHg)

Explanation: The ratio shows how much higher the systolic pressure is compared to diastolic pressure. Normal ratios typically fall between 1.5 and 2.0.

3. Importance of BP Measurement

Details: Blood pressure measurement is fundamental for assessing cardiovascular health. The ratio can sometimes indicate arterial stiffness when interpreted by healthcare professionals.

4. Using the Calculator

Tips: Enter both systolic and diastolic blood pressure values in mmHg. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a normal BP ratio?
A: Typically between 1.5 and 2.0, but this varies by individual and should be interpreted by a healthcare provider.

Q2: Is the BP ratio a diagnostic tool?
A: No, it's supplementary information. Absolute BP values and clinical context are more important for diagnosis.

Q3: When should BP be measured?
A: In a rested state, seated position, with proper cuff size. Avoid caffeine, exercise, or stress before measurement.

Q4: What affects BP ratio?
A: Arterial stiffness, age, and cardiovascular health can influence the ratio between systolic and diastolic pressures.

Q5: Should I be concerned about my BP ratio?
A: Discuss any concerns with your healthcare provider. The ratio alone doesn't indicate health problems.
