Hemodynamics

Question 1

HIGHEST arterial BP

Measured after the heart CONTRACTS (systole)

Answer 1

Systolic Pressure

Question 2

LOWEST arterial BP

Heart RELAXED (diastole)

Answer 2

Diastolic Pressure

Question 3

Difference b/w Sytolic and Diastolic pressures

Answer 3

Pulse Pressure

PP = SP-DP
PP=SV/arterial compliance

stroke volume - most important determinant of pulse pressure

DECREASE capacitance (aging) —> INCREASE pulse pressure

Question 4

Right Atrial Pressure

Answer 4

Central Venous Pressure

Question 5

Left Atrial Pressure

Answer 5

Pulmonary Capillary Wedge Pressure

Question 6

Pulse Pressure

Answer 6

Systolic Pressure - Diastolic Pressure

Question 7

Pulse Pressure

Answer 7

SV/arterial compliance

Question 8

Most important determinant of pulse pressure

Answer 8

Stroke volume

Question 9

Mean Arterial Pressure (MAP)

normal MAP - 100

Answer 9

SBP + (2x DBP) divided by 3

Question 10

Ejection Fraction

Answer 10

SV/EDV

Question 11

Normal Pulmonary Artery Pressure

Answer 11

15-25 0r 8-10 mmHg

Question 12

Normal ratio of systemic to pulmonary pressure

Answer 12

3:1

Question 13

Right Atrial Pressure

Answer 13

Central Venous Pressure

Question 14

Measured using SWAN GANZ catheter

Estimates LEFT ATRIAL PRESSURE

Answer 14

Pulmonary Capillary Wedge Pressure

Question 15

In exercise among cardiac transplant patients, cardiac output increases mainly d.t. increase in

Answer 15

Stroke Volume

Question 16

Increases when CVP increases

Answer 16

ANP

Question 17

INCREASED (Widened) Pulse Pressure

Answer 17

well conditioned endurance runner
old age
aortic regurgitation
aortic sclerosis
severe IDA
arteriolosclerosis
hyperthyroidism

Question 18

DECREASED (Narrowed) Pulse Pressure

Answer 18

Heart failure
Blood loss
Aortic stenosis
Cardiac tamponade
