Shock part 1

Question 1

Shock (decrease in _____) —–>Hypoxia—>Death

Answer 1

Blood pressure

Question 2

In shock

Unable to deliver enough blood to tissues: Hypo-perfusion

Organ malperfusion

Low O2 ( _________)

which leads to multiple organ failure and death

Answer 2

hypoxia

Question 3

Shock aka circulatory failure

Question 4

Effects of shock are reversible in the early stages…

Question 5

Blood flow is equal to cardiac output

Question 6

CO=

Answer 6

HRxSV

Question 7

BP(Blood pressure)=Blood flow x ________

Answer 7

total peripheral resistance

Question 8

Mortality rate is high so more than 50% or 60% in septic shock

Question 9

Shock is a life-threatening manifestation of circulatory shock

Circulatory failure means decrease in blood pressure–>insuiffcient blood flow–>insufficient O2 delivery–>cellular and tissue hypoxia–>cell and tissue dysfunction–>multiorgan failure–>death

Question 10

Shock–> lack of tissue perfusion–>lack of O2–> switch to __________metabolism (for energy production)—>increase in lactate (lactic acid)—>_________(decrease in pH)

Answer 10

anaerobic

metabolic acidosis

Question 11

3 determinants of stroke volume are what? (exam question)

Answer 11

contracility, preload, and afterload

Question 12

If you increase contracility and preload you increase what?

Answer 12

stroke volume

Question 13

If you increase afterload you decrease ___________

Answer 13

stroke volume

Question 14

If you increase the blood volume you increase the stroke volume

Question 15

Blood volume effects blood flow
