Cardiovascular Flashcards
(36 cards)
JVD is a sign of what?
increased right atrial pressure
How do u position the pt for JVD analysis?
Raise the head of the bed or examining table to 30°
Turn the patient’s head gently to the left
Identify the topmost point of the flickering venous pulsations
How do u measure JVD?
Place a centimeter ruler upright on the sternal angle (Angle of Louis)
Place a card or tongue blade horizontally from the top of the JVP to the ruler, making a right angle
Measure the distance above the sternal angle in centimeters, add 5cm (since the Right Atrium is 5cm below sternal angle
A 0 - 8 centimeter elevation is normal
Before you palp the carotids, what should u do?
auscultate for bruits
What should u hear in the carotids normally?
nothing
What will u hear if there is carotid stenosis?
you may hear a Whooshing sound – like the Karotkoff sounds when checking BP
How do u position the pt for a chest palpation?
Stand on the right side of the patient
Drop gown, keep sheet over lower extremities
Palpate shape of chest wall, PMI, Heaves
How do u find the PMI?
Inspect the left anterior chest for a visible PMI
Using your fingerpads, palpate at the apex for the PMI
What are the characteristics of the PMI?
Tapping, or normal
Sustained — suggests LV hypertrophy from hypertension or aortic stenosis, or
Diffuse — suggests a dilated ventricle from congestive heart failure or cardiomyopathy
How do u measure the PMI?
Locate the PMI by interspace and distance in centimeters from the midsternal line
What things are u palpating for in the chest?
heaves or thrills
What is systole?
The right ventricle pumps blood into the pulmonary arteries (pulmonic valve is open)
The left ventricle pumps blood into the aorta(aortic valve is open)
What is diastole?
The ventricles relax
Blood flows from the right atrium → right ventricle (tricuspid valve is open)
Blood flows from the left atrium → left ventricle (mitral valve is open)
What is the diaphragm of the stethoscope best for?
high-pitched sounds like S1, S2, and also S4 and most murmurs
What is the bell of the stethoscope best for?
low-pitched sounds like S3 and rumble of mitral stenosis
What is S1 and S2?
S1 closure of AV valves
S2 closure of Semilunar valves
What is the splitting of S2?
Right sided pressures are lower than the left
Right sided events occur slightly later than left
Example: the aortic valve closes slightly before the pulmonic valve (A2 before P2)
Inspiration causes (accentuates) a split
With expiration the split may disappear
What is an ejection click?
early systole
Sound of diseased aortic valve opening
What is an opening snap?
early diastole
Sound of diseased mitral valve snapping open
What is S3?
Rapid deceleration of blood
Decreased compliance such as heart failure
May be normal in children and young adults
What is S4?
Atrial kick against non-compliant ventricular wall
What are the shapes of murmurs?
Crescendo, decrescendo, or both (sometimes called diamond-shaped)
Give the grades of murmurs from 1-6
Grade 1 – very faint, possibly not heard in all positions
Grade 2 – Easily heard but faint
Grade 3 – Moderately loud
Grade 4 – Loud with palpable thrill
Grade 5 – Heard with stethoscope partially off chest
Grade 6 – Heard with stethoscope off the chest
What do u hear in left lateral decubitis?
Mitral stenosis, S3, S4
