Blood Pressure Index Calculator

Formula

To calculate the Blood Pressure Index (BPI):

\[ BPI = \frac{2 \times DBP + SBP}{3} \]

Where:

\(BPI\) is the Blood Pressure Index
\(DBP\) is the Diastolic Blood Pressure (mmHg)
\(SBP\) is the Systolic Blood Pressure (mmHg)

What is a Blood Pressure Index?

A Blood Pressure Index, also known as a Blood Pressure Ratio, is a measure used to evaluate an individual’s blood pressure levels. It is calculated by dividing the systolic pressure (the top number, representing the pressure in the arteries when the heart beats) by the diastolic pressure (the bottom number, representing the pressure in the arteries when the heart is at rest). This index provides a comprehensive view of a person’s cardiovascular health and can help identify risks of hypertension or other heart-related conditions.

Example Calculation 1

Let's assume the following values:

Diastolic Blood Pressure (DBP) = 80 mmHg
Systolic Blood Pressure (SBP) = 120 mmHg

Using the formula:

\[ BPI = \frac{2 \times 80 + 120}{3} = 93.33 \]

The Blood Pressure Index is 93.33.

Example Calculation 2

Let's assume the following values:

Diastolic Blood Pressure (DBP) = 70 mmHg
Systolic Blood Pressure (SBP) = 110 mmHg

Using the formula:

\[ BPI = \frac{2 \times 70 + 110}{3} = 83.33 \]

The Blood Pressure Index is 83.33.
