Matlab Code 1: Arterial resistivity index (ARI) is a measure of pulsatile blood

Question

Matlab

Code 1: Arterial resistivity index (ARI) is a measure of pulsatile blood flow that indicates the resistance to blood flow through an artery. ARI is calculated with the following formula. systoliastote) Vsystole Vsystole is the velocity during contraction and vaiastote is the velocity during relaxation. The velocity is measured using Doppler ultrasound and one data point is recorded every 3 ms. A Doppler recording is saved in the file DopplerData.csv. Write a script that does the following: Plot Velocity (cm/s) over time (ms) with appropriate title, x-label, and y-label. Calculate ARI and display to the Command Window. Note: vsystole is the maximum velocity in the dataset. vaiastole is the minimum velocity in the dataset Calculate the instantaneous heart rate from Doppler data, and display to the command window as beats per minute 1. 2. 3.

Explanation / Answer

Solution:

1)

For plot we use the function plot() in matlab

The command is

2)

You can ask the user to enter vsystole and vdiastole or

you can initilize i in the code and calculate the ARI

by the formula

3)

Similarly, the heart rate can also be calculated based upon the formula
