1. List the blood flow thru the heart
|
SVC, IVC and CS dump into RA thru TV to RV thru the PV to PA to Lungs.
Then to pulmonary veins into LA thru MV to LV out the aortic valve to the body |
|
|
2. Name the two AV valves
|
Tricuspid and Mitral
|
|
|
****3. Preload
|
How full a chamber is. The amount of blood sitting in the heart right before it contracts (in end diastole). Each chambers has its own preload. ***LV preload is measured by LVEDP
|
|
|
****4. Afterload
|
The amount of Resistance the ventricle has to overcome to eject blood out. Afterload is equal to the MEAN ARTERIAL PRESSURE (MAP)
|
|
|
5. RV afterload is determined by _______ artery pressure.
|
Pulmonary
|
|
|
6. LV afterload is determined by______ pressure
|
Aortic
|
|
|
7. Two Semilunar valves
|
Aortic and Pulmonic
|
|
|
***8. Vascular resistance/pressure is most influenced by?
|
radius of vessel
|
|
|
9.__________ converts the mechanical pressure to an electrical signal that is displayed on a video monitor.
|
Pressure Transducer
|
|
|

For best waveform results, pressure tubing should be short and stiff. |

15. "a" wave on RA pressure represents?
|
atrial contraction,occurs within the PR interval on ekg
|
|
|
16. X decent on RA waveform=
|
atrial relaxation
|
|
|
****17. The " __ " wave corresponds to right ventricular Contraction causing the triCuspid valve to bulge towards the right atrium. Found directly following the QRS on ekg
|
C wave
|
|
|
18. A prominent "a" wave in RA pressure is caused by:
|
Tricuspid stenosis, RV Hypertrophy, Right sided heart failure, Tamponade, Complete heart block
|
|
|
19. A prominent V wave in RA pressure caused by?
|
Tricuspid Regurg and Right sided heart failure
|
|
|
20. Normal RA pressure
|
0-8 mean 5
|
|
|
21. Normal RV pressure
|
15-30 systolic 0-8 diastolic
|
|
|
***22. RV systolic pressures are increased in?
|
Right sided heart failure
Pulmonary valve stenosis RV infarct Pulmonary hypertension |
|
|
23. PA systolic is approximately the same as the RV systolic pressure.
True or false? |
True
|
|
|
****24. Normal PA pressures
|
15-30 mm Hg systolic
8-15 mm Hg disastolic |
|
|
****25. PAWP is the most accurate reflection
|
Left atrial pressure
LVEDP or preload |
|
|
26. Normal LV pressures
|
systolic: 90-140 mm Hg
LVEDP 5-12 |
|
|
****27. After the transducer is zeroed, it falls off the table to the floor. The pressure being read is now reading?
|
Higher
|
|
|
****28. When performing a thermodilution cardiac output, the operator injects 10ml of saline into the _____ and the temperature change is measured in the __________.
|
RA and PA
|
|
|
29. Respiratory Variations are caused by
|
Upper R lobe lung pressess on Vena Cava causing respiratory variations (normal variation 0-10mm of pressure)
|
|
|
