Workshop Flashcards
1
Q
What happens to compliance of arteries as you age?
A
Reduced
2
Q
What happens to the velocity of primary and reflected waves as you age? What does this mean?
A
Increases - reflected waves get back at same time as systolic beat so cannot help push blood into the coronary arteries
3
Q
What happens to diastolic BP as you age?
A
Decreases - not as easy for blood to flow into coronary arteries
4
Q
What does elastin allow arteries to do?
A
Recoil so that when there is less blood present they can push it down the artery
5
Q
When does blood flow through the coronary arteries?
A
Diastole
6
Q
What is the role of the reflected wave?
A
Come back just after systolic beat to provide extra pressure to push blood into coronary arteries
