1

Which valves are the AV valves?

Which valves are the Semilunar Valves?

AV = Tricuspid and Mitral

Semilunar = Pulmonica and Aortic

2

What does the "LUB" sound coincide with?

closure of AV valves

3

What does the "DUB" sound coincide with?

closure of Semilunar valves

4

How many phases of the Cardiac Cycle?

7

5

MAP:

Mean Arterial Pressure must be at least --- to maintain adequate blood flow through coronary arteries.

60 mmHg

6

MAP:

Mean Arterial Pressure must be --- to maintain perfusion through major body organs like kidneys and brain.

60-70 mmHg

7

When does coronary artery blood flow to the myocardium?

during DIASTOLE

8

Cardiac Cycle:

When does the "Lub" sound happen?

When does the "Dub" sound happen?

Lub = MITRAL (AV) Valve closes

Dub = AORTIC (Semilunar) valve closes

9

Diastole and Systole:

--- consists of relaxation and filling of atria and ventricles and accounts for two-thirds of cardiac cycle.

Diastole

10

Diastole and Systole:

--- consists of the contraction and emptying of of atria and ventricles and accounts for one-third of cardiac cycle.

Systole

11

How is Cardiac Output calculated?

CO = HR x SV

12

What is Stroke Volume?

amount of blood ejected by left ventricle during each contraction

13

Normal HR for adult is ---

60-100

14

How is BP calculated?

BP = SV x Systemic Vascular Resistence (SVR)

15

How is MAP calculated?

SBP + DBP *2 / 3

16

What is a Normal MAP?

70-100

17

What is Systolic BP?

What is Diastolic BP?

SBP = pressure generated by left ventricle to distribute blood into aorta

DBP = pressure against arterial walls during relaxation phase of heart

18

What is Central Venous Pressure?

reflects filling pressures of the right side of the heart

Normal value is 2-5 mmHg

19

What is normal CO?

4-6 L/min

20

What is Cardiac Index (CI)?

adjusts CO for body size

Normal Value is 2.2-4.0 L/min/meters squared

21

How is SV calculated?

(CO / HR) x 1000 = SV

22

What is normal SV?

60-70 mL

23

What is Systemic Vascular Resistence (SVR)?

the resistence against which the left ventricle must pump to eject its volume

ie: Afterload

normal value is 800-1400 dynes/sec/cm

24

What is normal SVR?

800-1400 dynes/sec/cm

25

What is the best indicator of fluid balance?

weight

2.2 lb = 1 kg = 1 L

26

How much does one liter of fluid weigh?

1 L = 1 kg = 2.2 lb

27

--- are located in arch of aorta and respond when walls are stretched by increased BP

Baroreceptors

***they in turn inhibit the vasomotor center in the Pons and Medulla which leads to drop in BP

28

Heart Cath:

Which side is typically done first and goes through the femoral vein into the IVC?

Right Sided Cath

***Left Sided Cath goes through femoral artery against blood flow

29

When performing Hemydynamic Monitoring, what do we set the Pressure Bag to?

300 mmHg

30

What is Positioning for Hemodynamic Monitoring?

HOB can be 0-60 degrees if patient is supine
