How can decreased cardiac output be caused by abnormal fluid volume?

Physiology. The amount of blood the left ventricle can pump (stroke volume) is directly related to "preload" which is based on the venous return to the heart. If volume is contracted from bleeding, diuresis, vasodilation, or poor intake, preload is reduced, venous return is reduced, stroke volume is reduced &, if increased heart rate can't compensate for the reduction, then cardiac output is also reduced.

Overloading. Low cardiac function may not be able to keep up with too much volume and the fluid backs up in places like the lung, neck, abdomen, and legs. Too much volume can overwhelm a borderline heart already weak. When the heart cannot keep up the needed cardiac output (liters per min) and making the pump work harder increasing pressure inside the heart, and dilating the chamber getting into a bad cycle.

How can decreased cardiac output be caused by increased fluid volume?

You have it reverse. Heart rate x stroke volume = cardiac output and thus if stroke volume decreases, cardiac output decreases or if heart rate decreases cardiac output decreases. Read more...

How is decreased cardiac output caused by increased fluid volume and decreased fluid volume?

Stroke volume. Cardiac output is determined by heart rate and volume of blood pumped by heart in each heartbeat (stroke volume). Increased fluid volume increases the stroke volume and therefore cardiac output. Decreased fluid volume decreases the stroke volume and therefore cardiac output. Read more...
CO explained. Cardiac output is the amount of blood your heart pumps, measures in liters per minute. If it is decreased it means the heart is unable to pump as strongly as it should. That means the heart can't keep up with the volume returning to it. Read more...

How can decreased cardiac output be caused by either increased fluid volume and decreased fluid volume?

Cardiac output. When systolic dysfunction is present, volume overloading can result in decreased stroke volume and cardiac output. In any cardiac status, decreased intravascular volume will result in decreased cardiac output. Read more...

Can decreased cardiac output cause somebody delirium?

Yes. If by delirium you mean changes in your state of consciousness then yes. Decreased cardiac output means that your heart is not pumping the needed amount of blood per minute to maintain normal body functions including that of your brain. Delirium can have many other causes that are probably more common than low cardiac output so check with your doctor. Read more...
Low cardiac output. leads to low blood pressure and less oxygen and glucose for your brain. This is a well known cause of delirium and encephalopathy. Low cardiac output can be caused by cardiomyopathy, heart failure or severe systemic illness such as sepsis. It is a very serious condition. Read more...

Why? Would someone in renal failure have decreased cardiac output?

Many reasons. Decreased cardiac output can contribute to reduced kidney function. Kidney disease is often associated with heart problems that reduce cardiac output. High blood pressure and volume overload with kidney failure can also reduce heart output. It's often difficult to sort out cause and effect in these situations. Read more...

What is the relation of hypertension and decreased cardiac output?

Depends. In theory, the harder it is for blood to leave the heart (as when BP is very elevated) the less of it will be pumped out per beat or per minute (decreased output). For this scenario to occur though the BP will need to be significantly elevated. In most cases a mild or even moderate elevation in BP will not have a tangible effect on cardiac output. Read more...
Complicated. It is an indirect relationship. Hypertension over time can lead to changes in the heart muscle and heart function. It may eventually lead to heart failure. When this ensues the output of the heart can eventually decline and cause serious symptoms. In the earlier stages if hypertension cardiac output actually goes up. Read more...

What is the relation of hypertension and? Decreased cardiac output?

Cardiac damage. Hypertension, if not treated, leads to myocardial hypertrophy, accelerated atherosclerosis resulting in inadequate blood supply to heart muscle that leads to impaired heart function and decreased cardiac output/heart failure. Read more...
Hypertension. High blood pressure usually implies an increased peripheral vascular resistance for a time the heart can keep up with the resistance late in the course the heart begins to not be able to generate the stroke volume against the resistance and cardiac output may fall. If abnormal ventricular function is present, cardiac output may fall earlier. Read more...
