Resistive Index Calculator
Introduction
Calculators play a crucial role in various fields, aiding in swift and accurate computations. One such calculator that finds utility in the medical field is the Resistive Index Calculator. This tool assists in assessing vascular resistance in different organs, especially in medical imaging studies like Doppler ultrasound.
How to Use
Using the Resistive Index Calculator is straightforward. Enter the required parameters, and the calculator will compute the resistive index, providing valuable information for medical professionals. To use the calculator, follow these simple steps:
- Input the Peak Systolic Velocity (PSV) value.
- Enter the End Diastolic Velocity (EDV) value.
- Press the “Calculate” button to obtain the Resistive Index.
Formula
The Resistive Index (RI) is calculated using the following formula:
Where:
- PSV is the Peak Systolic Velocity,
- EDV is the End Diastolic Velocity.
Example Solve
Let’s consider an example:
- PSV = 80
- EDV = 40
Using the formula:
So, the Resistive Index in this example is 0.5.
