exam 1

Question 1

MODs

Answer 1

multiple organ dysfunction syndrome

massive inflammatory response affecting all organs causing dysfunction and ultimately irreversible failure

Question 2

goal of hemodynamic monitoring

Answer 2

maintain adequate tissue perufsion

Question 3

what will cause a change in ejection fraction

Answer 3

left sided systolic heart failure

Question 4

preload

Answer 4

volume in the ventricle at the end of diastole

Question 5

afterload

Answer 5

resistance the ventricle has to overcome to send blood to the body the lungs

Question 6

what measures left ventricular preload

Answer 6

PAWP

Question 7

what measures right ventricular preload

Answer 7

CVP

Question 8

Allens test

Answer 8

pinch off ulnar and radial arteries; hand will turn white.
Let one side go, if color returns we can insert art line

Positive Allens test is good

Question 9

MAP

1. normal #?
2. equation

Answer 9

1. 70-105

2. (Diastolic x 2) + (systolic) divided by 3

Question 10

normal pH

Answer 10

7.35-7.45

acidic – alkalotic

Question 11

normal PaCO2

Answer 11

35-45

alkolotic – acidic

Question 12

normal bicarbonate

Answer 12

22-26

acidic – alkolotic

Question 13

purpose of CVP monitoring

Answer 13

for pt’s w/ significant alteration in fluid volume, measures filling pressures of right side of heart

Question 14

normal SvO2

Answer 14

60-80%

Question 15

normal CVP

Answer 15

2-8 mmHg

Question 16

what does CVP measure?

Answer 16

approximates right ventricular filling pressure (blood in the right atrium)

(not a good indicator of left ventricular problems)
