FOR AORTIC STENOSIS WHAT IS THE PAUSE BETWEEN S1 AND WHEN WE START HEARING THE MURMUR? |
|
Definition
ISOVOLUMETRIC CONTRACTION PHASE |
|
|
Term
FOR AORTIC STENOSIS WHICH PRESURE IS HIGHER? |
|
Definition
THERE IS AN INCREASE IN VENTRICULAR PRESSURE |
|
|
Term
WHY IS THE VENTRICULAR PRESSURE RISING WITH AORTIC STENOSIS? |
|
Definition
THE BARORECEPTORS. DON'T THINK OF CARDIAC DYNAMICS BEING REGULATED BY PRESURE IN THE VENTRICLES. IT IS REGULATES BY PRESSURE IN THE ARTERIES |

Term
WHAT IS OUR B/P GOING TO BE WITH AORTIC STENOSIS? |
|
Definition
NORMAL ALTHOUGH SYSTOLIC MIGHT BE A LITTLE LOW. |
|
|
Term
FOR AORTIC STENOSIS WHICH PEAK COMES FIRST? |
|
Definition
WE END UP WITH A PEAK IN LVP PRIOR TO PEAK IN AORTIC PRESSURE. THE AORTIC PRESSURES DEVELOP PRESSURES MORE SLOWLY THAN VENTRICULAR PRESSURE. |
|
|
Term
WHY DOES THE AORTIC PRESSURE WITH AORTIC STENOSIS DEVELOP PRESSURES MORE SLOWLY? |
|
Definition
|
|
Term
HOW DO WE MEASURE THE SEVERITY OF AORTIC STENOSIS? |
|
Definition
MEASURE THE DIFERENCE BETWEEN LVP AND AORTIC PRESSURE DURING PEAK SYSTOLE. THE LARGER THE GRADIENT THE MORE SEVERE THE STENOSIS. |
|
|
Term
WHAT TYPE OF MURMUR SOUND DO YOU HEAR WITH MITRAL STENOSIS? |
|
Definition
DECRESCENDO/CRESCENDO. THE MURMUR GETS QUIETER AND AT THE END GETS LOUDER. |
|
|
Term
FOR MITRAL STENOSIS WHAT IS THE SOUND FROM THE ATRIAL KICK? |
|
Definition
WHEN WE HAVE ATRIAL KICK AND MITRAL STENOSIS THERE IS TURBULENT FLOW ALL OVER AGAIN. WE HAVE A DECRESCENDO CRESCENDO. |
|
|
Term
FOR MITRAL STENOSIS WHAT IS THE ATRIAL PRESSURE DOING? |
|
Definition
IT IS INCREASES THROUGHOUT THE ENTIRE CARDIAC CYCLE. |
|
|
Term
HOW DO WE MEASURE SEVERITY OF MITRAL STENOSIS? |
|
Definition
THE MORE SEVERE THE STENOSIS THE HIGHER THE LAP. |
|
|
Term
WHAT IS THE AFTERLOAD WITH AORTIC REGURGITATION? |
|
Definition
IT IS DECREASED SOMEWHERE BETWEEN 45-50 DEPENDING. |
|
|
Term
IS THERE A DICROTIC NOTCH WITH AORTIC INSUFFICENCY? |
|
Definition
NO BECAUSE THERE IS NO AOV CLOSURE. THERE IS A DECREASE IN AOEDP. |
|
|
Term
WHAT TYPE OF SOUND DO YOU HEAR WITH A AORTIC INSUFFICIENCY? |
|
Definition
|
|
Term
HOW DO WE MEASURE SEVERITY OF MITRAL INSUFFICENCY? |
|
Definition
|
|
Term
WHAT IS WRONG WITH THE MITRAL INSUFFICIENCY GRAPH? |
|
Definition
THE V WAVE. MITRAL STENOSIS IS ELEVATED THROUGH ENTIRE CARDIAC CYCLE. THE V WAVE WITH MITRAL INSUFFICENCY IS ONLY ELEVATED DURING VENTRICULAR SYSTOLE. AS INSUFFICIENCY BECOMES MORE AND MORE SEVER THE SLOPE OF THE V LINE IS GOING TO INCREASE. |

Term
WHERE IS MORE THAN HALF OF THE ENTIRE BLOOD VOLUME LOCATED AT? |
|
Definition
IN THE SYSTEMIC VENOUS CIRCUIT. |
|
|
Term
HOW MUCH CO DOES THE LUNGS RECEIVE? |
|
Definition
LUNGS RECEIVE AS MUCH BLOOD AS ENTIRE REST OF BODY ADDED TOGETHER. IT IS 100% OF CO. |
|
|
Term
HOW DO WE GET REDISTRIBUTION OF CO? |
|
Definition
VASODILATE ACTIVE BEDS AND VASOCONSTRICT INACTIVE BEDS. |
|
|
Term
WHICH AREA OF THE BDY HAS THE GREATEST AMOUNT OF TOTAL CROSS SECTIONAL AREA? |
|
Definition
|
|
Term
WHERE IS THE PRESSURE DROP GREATEST AMONG? |
|
Definition
THE ARTERIOLES. THAT IS THE SITE OF VASCULAR RESISTANCE |
|
|
Term
DOES THE VENOUS SYSTEM HAVE TO HAVE MUCH LOWER PRESSURE THAN THE CAPILLARIES? |
|
Definition
YES. IF NOT YOU END UP WITH RETROGRADE FLOW. |
|
|
Term
WHAT IS THE FORMULA FOR VOLTAGE? |
|
Definition
CURRENT X RESISTANCE V = IXR |
|
|
Term
TALKING ABOUT FLOW OF ELECTRONS THROUGH A WIRE. WHAT DETERMINES THE FLOW? |
|
Definition
THE VOLTAGE. HOW MUCH FLOW DO I HAVE DEPENDS UPON RESISTANCE. |
