Hemodynamics: Preload Exam Actual
Questions and Answers 2026
Components of preload -
correct answer ✅preload is the volume at the end of diastole,
when the ventricle is completely relaxed.
actually a measure of stretch, but we can't directly measure that so
we measure volume in the ventricle
Right atrial preload (RAP), other names -
correct answer ✅central venous pressure (CVP))
Right ventricular end diastolic pressure (RVEDP)
RAP/CVP/RVEDP -
correct answer ✅amount of blood in the right ventricle at the end
of diastole
What does RAP/CVP/RVEDP reflect? -
correct answer ✅the compliance of that ventricle and the volume
returning from the body into the vena cava
How is RAP/CVP/RVEDP measured? -
correct answer ✅with a central venous catheter
, Hemodynamics: Preload Exam Actual
Questions and Answers 2026
Where is a central venous catheter placed? -
correct answer ✅in the internal jugular or subclavian vein
What does a central venous catheter "take a picture of"? -
correct answer ✅the tricuspid valve, you can "see it" opening
Left atrial preload (LAP) other names -
correct answer ✅pulmonary artery wedge pressure (PAWP)
Left ventricular end diastolic pressure (LVEDP)
What does LAP/PAWP/LVEDP measure? -
correct answer ✅the amount of blood in the left ventricle at the
end of diastole
What does LAP/PAWP/LVEDP reflect? -
correct answer ✅the compliance of the left ventricle and the
volume returning from the pulmonary system into the left side of
the heart
