Unit 2 study guide 2

Question 1

PAP- pulmonary artery pressure

Answer 1

15-26

Question 2

pulmonary artery catheter

Answer 2

multi-lumen cath w capacity to measure right atrial and indirect left arterial pressure (pulmonary artery wedge pressure)

Question 3

left ventricular end-diastolic pressure (LVEDP)

Answer 3

tip of cath in pulmonary art

Question 4

pulmonary artery wedge pressure-3

Answer 4

• pressure measured during balloon inflation
• left artial pressure and LVEDP
• 4-12

Question 5

elevated PAWP-4

Answer 5

left ventricular heart failure, hypovolemia, mitral regugitation, intra cardiac shunt

Question 6

right atrial pressure (RA)

Answer 6

8-15

Question 7

abnormal RA-2

Answer 7

high-right ventricular failure,

low-hypovolemia

Question 8

cardiac output

Answer 8

vol of blood pumped in 1 min

-4-8

Question 9

cardiac index

Answer 9

measurement of CO adjusted for body surface area

-2.5-4.2

Question 10

stroke volume

Answer 10

volume ejected w each heart beat, stretch of ventricle

Question 11

systemic vascular resistance-3

Answer 11

opposition encountered by left vent

• low-dilated
• high-constriction

Question 12

preload

Answer 12

vol within ventricle at the end of diastole

Question 13

afterload-3

Answer 13

forces opposing ventricular ejection

• vasodilators can reduce
• stroke volume resistance

Question 14

before placing PA cath-6

Answer 14

electrolytes, acid-base, O2, and coags

-hypokalemia, hypomagnesaemia

Question 15

systole

Answer 15

pressure when heart contracting and exertine most force on arteries

Question 16

diastole

Answer 16

pressure when heart relaxed and exerting least force on arteries

Question 17

central venous pressure

Answer 17

pressure occuring in right atrium at end-diastolic

Question 18

phlebostatic axis

Answer 18

imaginary line hlfway between front and back and 4th intercostal space

Question 19

dampen

Answer 19

altered reading because transducer too high or low
