Assessing the Heart and Cardiovascular System Flashcards
How many chambers are there in the heart and what are they
4
right atrium, right ventricle, left atrium, left ventricle
How many valves does the heart have and what are they
4
aortic, tricuspid, pulmonary, mitral
How are the heart valves controlled
through blood pressure changes
Veins
carry deoxygenated blood to the heart
Where are veins
close to the surface
Arteries
carry oxygenated blood to the body
Where is the heart positioned
on the left side between the 2nd and 5th intercostal spaces
perfusion
a continuous supply of oxygenated blood through blood vessels to the vital organs
What two phases fill and empty the heart’s chambers
systole and diastole
Systole
contraction of the ventricles (emptying)
Diastole
relaxation of the ventricles (filling)
What are the central vessels
carotid arteries, jugular veins
What do jugular veins do
return blood from the vein to the superior vena cava
What are the peripheral vessels
arteries and veins
What do diseases in the vascular system cause
problems with the delivery of O2 and nutrients to tissues, and elimination of CO2 and wastes from cellular metabolism
What does the pressure from each heartbeat cause
arteries to expand and recoil
what questions should you obtain regarding a clients cardiovascular history (6)
demographic data, health history, family history, cardiovascular history, nutrition history, lifestyle/health promotion activities
What do you listen for during cardiovascular assessments (5)
cardiac rate, rhythm, abnormal heart sounds, S1-S4, murmurs
