Want this question answered?
Preload is caused by decreased blood volume in ventricles. Therefore, decreased preload directly caused by bleeding, polyuria, dehydration.
Assess for signs of volume overload--dlyspnea, tachypnea, crackles or possible wheezes on auscultation, pulmonary edema, juglar vein distention and pitting edema of the ankles-- may indicate a problem with increased preload.
John is about to preload his truck with logs.
it decreases blood volume and preload
Preload is caused by decreased blood volume in ventricles. Therefore, decreased preload directly caused by bleeding, polyuria, dehydration.
if you find out tell me what preload is
Preload is the amount the pinion bearings are squeezed together by the pinion nut.
Severe dehydration will decrease preload because there won't be as much volume coming into the heart.
It decreases preload and afterload as a result of the dilation in the venous and arterial vasculature from the nitric oxide.
Afterload
There is no specific pinion nut torque. The pinion nut has to be tightened until the proper pinion preload is established. Pinion preload is what matters
aortic diastolic pressure
end-diastolic volume
it is the amount of blood available for the heart to pump when the ventricles contract
