Cardiovascular System Evaluation Flashcards
What position should the CV system evaluation be done in?
supine
The diaphragm is used to auscultate ____ pitched sounds
high
The bell is used to auscultate ____ pitched sounds
low
What 4 heart sounds can the diaphragm be used to hear?
- S1
- S2
- murmurs of aortic or mitral regurgitation
- pericardial friction
What 3 heart sounds can the bell be used to hear?
- S3
- S4
- murmurs of mitral stenosis
Describe the location of the aortic area
2nd intercostal space just right of sternum
Describe the location of the pulmonary area
2nd intercostal space just left of the sternum
Describe the location of the tricuspid area
Lower left sternal border, approximately the 4th to 5th intercostal space
Describe the location of the mitral area
5th left intercostal space, medial to the midclavicular line
Where can murmurs of both aortic and pulmonary origin be heard at?
3rd Left Intercostal Space
When first beginning assessment with the stethoscope you should use the diaphragm, what are the areas in which you should listen?
- Aortic Area
- Pulmonic Area
- Left 3rd ICS
- Left 4th ICS
- Left 5th ICS
- Apex
What sounds are you listening for when using the diaphragm?
S1 and S2
After assessing S1 and S2 with the diaphragm you should use the bell, what are the areas in which you should listen?
- Left 4th ICS
- Left 5th ICS
- Apex
Where and how should you listen for S1?
In the apex/tricuspid area with the diaphragm
What does S1 signify?
Closing of the mitral valves
Where and how should you listen for S2?
At the either the aortic or pulmonary areas with the diaphragm
S2 signifies the closing of what valves?
aortic and pulmonary
S1 corresponds with ventricular _____
S2 corresponds with ventricular _____
systole
diastole
What are S1 and S2 typically heard?
During inspiration
Where can S1 splitting best be heard?
over the tricuspid area
Where can S2 splitting be heard best?
over the pulmonary area
Both S1 and S2 splitting are considered normal and are indicative of what?
slight timing differences between closure of the left and right heart valves
When does S3 happen?
Immediately following S2 while the ventricle is filling rapidly (diastole)
What does S3 sound like?
“lub-dub-dub” or “lub-dub-dee” or “Kentucky”
