JVP, murmurs, auscultation heart Flashcards
Grade 1 murmur
faint, only heard after listener has tuned in; may not be heard in all positions
Grade 2 murmur
quiet, but heard immediately after placing stethoscope on chest
Grade 3 murmur
moderately loud
Grade 4 murmur
loud with palpable thrill
Grade 5 murmur
very loud with thrill, may be heard when stethoscope on chest partially
Grade 6 murmur
very loud with thrill, may be heard when stethoscope off chest completely
If murmur is heard on 2nd R. interspace where is it originating?
aortic valve
A murmur on which side of the heart varies with inspiration?
Right side
What does JVP reflect?
R. atrial pressure
Where is JVP best estimated and why?
R. internal jugular vein because it is the most direct channel into the R. atrium
What is the measurement from sternal angle to R. atrium, regardless of bed position?
5 cm
What amt do we add to the number we obtained to reflect the distance from R. atrium?
5 cm
What is a normal JVP?
less than 9cm
What diseases associated with increased JVP?
HF, tricuspid valve disease, pulmonic stenosis, pericardial disease
What disease associated with decreased JVP?
dehydration and hypovolemia
What do we do if patient hypovolemic and need to measure JVP?
Lower head of bed to as low as 0 degrees
What do we do if patient hypervolemic and need to measure JVP?
raise head of the bed to 60 or 90 degrees
What is a normal Kussmaul sign?
JVP falls with inspiration due to a decrease in pressure in expanding thorax cavity
What is an abnormal Kussmaul sign?
JVP will rise with inspiration due to impaired filling of R. ventricle because fluid in pericardial space or poorly compliant myocardium/pericardium
Where to find PMI?
5th IC space, 1cm medial to midclavicular line
Normal PMI diameter
less than 2.5cm
What are we looking for with PMI?
lift, heaves, thrills (buzzing)
