1

S1

Tricuspid & mitral valve closing

2

S2

Pulmonic and aortic valve closing

3

S3

CHF

4

Cardiac output determinants

Stroke volume & heart rate
(CO=SV x HR)

5

Cardiac index?
Normal values?

Ci= CO/BSA (body surface area)
2.5-4 L/min/m^2

6

Mean pulmonary artery pressure (pap) normal values?

16 mm Hg

7

Pulmonary artery systolic and diastolic

25/8

8

Pulmonary artery occlusion pressure (PAOP)

5-15 mm Hg

9

Where does the dista port of the PA catheter lie and how is this confirmed?

Pulmonary artery.
PA wave form and/or PAOP wave form

10

Mean arterial pressure (MAP)

[SBP x 2(DBP)]/3

11

Intra-aortic ballon pump (IABP)

-Decreases after load
-Decreases myocardial oxygen demand
-increases coronary perfusion
-limits size of infarcts/myocardial ischemia

Patient with cardiogenic shock or circulatory support

12

Sodium nitroprusside MOA:

Relaxes arterial/venous smooth muscle which decrease systemic vascular resistance AND preload

13

Sodium nitroprusside doses:

0.3-10 mcg/kg/min

14

What coronary artery would be occluded if STE was seen in leads II, III, and aVF

Right coronary

15

Why give morphine to MI patients?

Pain management and coronary vasodilation

16

Starling's Law?

The greater the volume of blood entering the heart during diastole, the greater the volume of blood that will be ejected during systole

17

CVP monitoring: A Wave

Atrial contraction

18

CVP Monitoring: C wave

Tricuspid valve elevation during early ventricular contraction

19

CVP Monitoring: V wave

Venous return against a closed tricuspid valve

20

Normal ICP

< 15

21

Preferred drug to treat brain swelling: and dose:

Mannitol 0.25-1 g/kg

22

Hyperventilation affect on cerebral vessels/blood flow

-Constriction of cerebral blood vessels
-decreases cerebral blood flow
-decreases ICP

23

Noninvasive ways to decrease ICP

-maintain normoglycemia
-maintain normothermia
-suction ONLY when indicated
-sedation

24

Normal cerebral perfusion pressure (CPP)
Calculation?

CPP= MAP-ICP
50-150 mm Hg

25

Cushing's triad

Hypertension
Bradycardia
Irregular respirations

26

Syndrome of inappropriate antidiuretic hormone (SIADH)?

Excessive reabsorption of water due to increased production of ADH

27

Common causes of SIADH

Carcinoma of the lungs
Various head problems

28

Roles of CRNA: pre-op

interview pt
establish rapport
review labs/medication
Determine type of anesthesia to deliver

29

Roles of a CRNA: peri-op

Preform safe induction
Maintain anesthesia
Safe emergence
Meticulous scrutiny of pt and monitors

30

Roles of CRNA: post-op

Adequate pain control
Monitor for post-op complications
