Hemodynamic Monitoring

Question 1

Hemodynamic Monitoring Goal

Answer 1

Optimizing oxygen delivery and tissue perfusion

Question 2

Hemodynamic Monitoring studies relationship between

Answer 2

HR, Blood Flow, oxygen Delivery, Tissue Perfusion

Question 3

Pressure = …

Answer 3

Pressure = Flow x resistance

Question 4

Cardiac Output formula

Answer 4

CO = HR x SV
4-8 L/ min

Question 5

Ejection Fraction

Answer 5

fraction of blood ejected with each beat
60-70% - normal

Question 6

Preload

Answer 6

Volume of blood in ventricle prior to contraction

Question 7

Causes of decreased preload

Answer 7

Hypovolemia - less volume can’t stretch
Atrial Arythmias - atria can’t fill
Tachy - decreased filling time
Decreases after load

Question 8

After load

Answer 8

resistance against flow

Ex- opening door against wind

Question 9

Causes of increased after load

Answer 9

systemic hypertension
aortic stenosis
coarction of the aorta

Question 10

Contractility

Answer 10

Force of ventricular contraction

(caused by meds, sympathetic nervous system, increase after load, increase HR)

Question 11

Arterial BP =

Answer 11

Arterial BP = CO x SVR

Question 12

Cardiac Index

Answer 12

Index better assessment based on body size
CI = CO / body surface area

Question 13

Noninvasive Hemodynamic

Answer 13

Blood pressure
Assessment of jugular venous pressure - JVD
Assessment if serum lactate levels (increase lactate indicates bad perfusion)

Question 14

Invasive Hemodynamic

Answer 14

1. ArterialPressure - most accurate
2. Pulmonary Artery Pressure - flow catether in pulmonary arteries
3. Right arterial pressure - R ♡ function

Question 15

Level in hemostatic monitoring

Answer 15

4th intercostal , midaxillary line

Question 16

Arterial Presure monitoring

Answer 16

for hemodynamic ally unstable, frequent lab work, vasoactive agents.

sites : radial artery, brachial, femoral

Question 17

Allen’s test

Answer 17

test blood flow to hands

Question 18

Arterial Pressure Monitoring Complications

Answer 18

Thrombosis
Embolism
Hemorrhage

Question 19

Pulmonary Artery Pressure Monitoring

Answer 19

Reflects L ventricular function
site: subclavian, jugular, femoral vein

measures PA systolic, PA diastolic, Pulmonary artery occlusion pressure

Question 20

Complication of PA catheter

Answer 20

Infection, Dysrhythmia, Air embolism, Thromboembolism, PA rupture , Pulmonary infarction

Question 21

Right Atrial Pressure

Answer 21

catheter in R atrium
pressure in R atria
2-6 mm Hg

Question 22

If you’re concerned about hypovolemia what invasive monitoring

Answer 22

Right atrial Pressure monitoring

Question 23

Complications of RAP

Answer 23

infection
pneumo
hemo
carotid
heart perforation
dysrhythmia
