1

what is hypotension

a blood pressure that inadequatley meets the demands of end organs

2

what is the function of the mean arterial pressure . What is an adequate mean arterial pressure

it tells us what the pressure is througout out entire body . 60

3

how do you calculate the mean arterial pressure

1/3 systolic presure + 2/3 diastolic pressure

4

what is a key indicator of hypotension

elevated HR (TACHY)

5

when do we consider shock

no response to fluids with MAP below 60

6

what are the 4 main causes of shock

hypovolemic, cardiogenic, distributive, obstructive

7

what MAP is considered shock

below 60

8

where are shock patients managed

ICU

9

Describe what shock is

shock is hypotension that does not respond to fluid resuscitation and resulting in end organ damage

10

what is the most important test for shock

EKG

11

What is the purpose of R heart cathertization

approx pressure of the R atrium

12

what are 3 ways to identify orthostatic hypotension

decrease in systolic BP BY 20

Decrease in diastolic BP by 10

INCREASE in HR by 30

13

what is one of the signs of shock

oliguria , elevated LDH increase lactic acid, increase cardiac markers etc

14

what is the preload like in hypovolemic shock

low preload

15

what is the cardiac output like in cardiogenic shock

low cardiac output because the heart is not working correctly

16

what is the afterload like in distributive shock

low after load

17

a right heart cathertization is also known as and what does it measure

swan ganz cathertization ,it measures the pressure of the left atrium

18

what are the 4 main causes of hypovolemic shock

burns
blood loss
GI loss
GU loss

19

a person has flat neck veins and bruising on the neck and around the umbilical cord with cool extremities . what kind of shock

hypovolemic

20

what is the main lab to do in hypovolemic shock

CBC

21

What are 4 causes of cardiogenic shock

1. low output- MI, heart failure
2. pulmonary causes- Pulmonary HTN, PE
3. high output -dysrythmia (a fib)
4. medication

22

#1 clue for cardiogenic shock

chest pain

23

what kind of neck veins are seen in cardiogenic shock

DISTENDED neck veins

24

what is the first step to do in cardiogenic shock

EKG, it will always be abnormal!

25

what are 3 causes of obstructive shock

cardiac tamponade
tension pneumothorax
constrictive pericarditis

26

what kind of chest pain is seen with obstructive shock

sudden onset that is sharp

27

a person has a hx of pericarditis what kind of shock are they at risk for

obstructive

28

what kind of heart sounds are heard in obstructive shock

muffled heart sounds

29

a person has the same pressure in all 4 chambers, what is this ? what kind of shock is this

cardiac tamponade - obstructive shock

30

a person has a tension pnumothorax how is it treated

place chest tube
