Preload is caused by decreased blood volume in ventricles. Therefore, decreased preload directly caused by bleeding, polyuria, dehydration.

Assessing preload in a patient without a central line?
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.

How do you use preload in a sentence?
John is about to preload his truck with logs.
What causes discoloration in a wheel bearing?
Heat. Bearings get discolored when they get too hot. They may have been insufficiently lubricated, or the preload was set improperly (wheel bearings need to have a little bit of preload to distribute the load more evenly).
Does diuretics decrease preload or afterload?
it decreases blood volume and preload
What agent causes no gag reflex and decreased eye movement and nausea and vomiting?

What is preload reset when replacing front wheel bearings on a 4x4?

What is pinion preload in a rear differential?
Preload is the amount the pinion bearings are squeezed together by the pinion nut.
How does dehydration affect preload?
Severe dehydration will decrease preload because there won't be as much volume coming into the heart.
What is a Nursing intervention for pulmonary Edema?
1. Administer Oxygen 2. Decrease preload by getting patient to sit upright and dangle legs over side of bed, this decreased blood return to heart 3. Relieve anxiety, decreasing sympathetic drive. 4. Administer medication safely to reduce preload, afterload and contractility of the heart 5. Reduce movements of the patient, to decrease oxygen demands.
What effect does Sodium Nitroprusside have on afterload and preload?
It decreases preload and afterload as a result of the dilation in the venous and arterial vasculature from the nitric oxide.
How can stroke volume can be altered?
Stroke volume is determined by three factors, altering any of them can change the stroke volume. These factors are preload, afterload, and contractility. The relationship is: SV = P*C/A What this means is that preload and contractility are directly proportional to the stroke volume and afterload is inversely proportional to stroke volume. If you increase preload (within certain limits), stroke volume will increase according to the Starling curve. Increasing contractility (many things can increase this), makes the heart pump harder and increases stroke volume. Increasing afterload decreases stroke volume. All of these can be reversed (decreasing preload and contractility = decreased stroke volume, etc). Get a good physiology book and it will explain all of this very well.
What causes tingling toes at altitude?
Decreased levels of oxygen in body at high altitudes.
Is it true that an anemia resulting from a decreased RBC number causes the blood to become more vicous?
