CVS Flashcards
Pulse pressure (PP)
Pulse pressure = systolic blood pressure - diastolic blood pressure
PP = SBP - DBP
Mean arterial pressure
MAP
MAP = DBP + (SBP-DBP)/3
MAP = DBP + 1/3PP
Cardiac output (CO)
Cardiac output = Heart rate x Stroke volume
CO = HR x SV
Mean arterial pressure (MAP)
- in terms of CO and TPR
Mean arterial pressure = cardiac output x total peripheral resistance
MAP = CO x TPR

What murmur is heard in Mitral valve stenosis?
Diastolic rumble between S2 and S1
What murmur is heard in Aortic valve stenosis?
Crescendo-decrescendo murmur between S1 and S2
What murmur is head in Mitral valve regurgitation?
Holosystolic murmur heard between S1 and S2
What murmur is heard in Aortic valve regurgitation?
Decrescendo early diastolic murmur between S1 and S2
Where is the aortic valve auscultated?
On the Right side in the 2nd intercostal space on the sternal edge
Where is the pulmonary valve auscultated?
On the Left side in the 2nd intercostal space on the sternal edge
Where can the tricuspid valve be auscultated?
On the Left side in the 4th intercostal space on the lower left sternal border
Where can the mitral valve be auscultated?
On the Left side in the 5th intercostal space, in the midclavicular line
Right sided heart murmurs are louder in ?
Inspiration due to decreased pressure in the chest
Left sided heart murmurs are louder in ?
Expiration as there is increased pressure in the chest
