AnswerPreload - ANSWERvolume left in the left ventricle at the end of diastole

total volume, and ventricular compliance
AnswerWhat drugs can affect preload? - ANSWERFurosemide and nitroglycerin
AnswerAfterload - ANSWERAmount of pressure heart has to overcome to pump blood
out
AnswerWhat drugs may affect afterload? - ANSWERVasoconstricters and vasodilators
AnswerContractility - ANSWERthe contractile force of the heart, how much will it take
to move the preload out against the afterload
AnswerWhat is the appropriate hold time after pulling an arterial line? - ANSWER5-10
min
AnswerWhat part of the heart does the PAOP affect? - ANSWERLeft ventricle
