Shock part 3

Question 1

____________=return of blood stored in venous system back to the heart

Answer 1

venous return

Question 2

increase in venous return means increase increase filling,increase preload, and increase cardiac output

Question 3

Venous system holds 3 to 3.5L (60 to 65%)

Question 4

Venous return determines what?

Answer 4

preload

Question 5

increase venous return—>increase preload–>increase cardiac output

Question 6

decrease venous return—>decrease preload–> decrease cardiac output

Question 7

what determines venous return?

Blood volume and ______________

Answer 7

vascular resistance

Question 8

increase blood volume your going to increase venous return and increase preload and increase stroke volume and increase cardiac output

Question 9

increase vascular resistance–>increase venous return–> increase preload--> increase stroke volume–> increase cardiac output

Question 10

If you increase afterload it won’t help with stroke volume

Question 11

If you have a higher mean arterial pressure that’s going to increase afterload

Question 12

if you increase afterload your going to decrease stroke volume and decrease cardiac output

Question 13

delete card

Question 14

When can afterload be super high?

Some major blockage

Dissecting aortic aneurysm
pulmonary ____________

Answer 14

pulmonary embolism

Question 15

When will contractility tank? myocardial infarction,__________

Answer 15

heart failure

Question 16

decrease contractility means decrease in stroke volume and decrease in cardiac output

Question 17

BP=cardiac output x_____________

Answer 17

total peripheral resistance

Question 18

Cardiac output= heart ratex__________

Answer 18

stoke volume
