Volume of blood ejected by heart each minute insertion to the size of the person (BSA) -
CORRECT ANSWER - Cardiac index



What is stroke volume? - CORRECT ANSWER - Volume of blood pumped out by one
ventricle with each beat


What is SVR? - CORRECT ANSWER - Systemic vascular resistance is resistance that the
left ventricle must overcome to eject a volume of blood; generally as SVR increases, CO falls

, What is PAWP/PAOP? - CORRECT ANSWER - Pulmonary artery wedge pressure. It
measures pressures generated by the left ventricle. It is used to assess left ventricular function.
Measured with a pulmonary artery catheter (Swan).


What is the significance of BUN? - CORRECT ANSWER - Measures how much of the
waste product you have in your blood. If your kidneys are not able to remove urea from the
blood normally, your BUN level rises. Heart failure, dehydration, or a diet high in protein can

(PT) is a test used to help detect and diagnose a bleeding disorder or excessive clotting disorder;
the international normalized ratio (INR) is calculated from a PT result and is used to monitor
how well the blood-thinning medication (anticoagulant) warfarin (Coumadin®) is working to
prevent blood clots. International Normalized Ratio should be 2-3 while taking Warfarin.


What is the significance of aPTT/PTT? - CORRECT ANSWER - Measurement of how
long it takes for your blood to clot. Should be 1.5-2x the normal value while on Heparin.

that pull calcium out of your bones, making them weak.
