Least cardiac output is used by which organ..?

Least cardiac output is used by which organ..?

Please clarify: I'm not sure where you are going with this question but I will do my best to help. Most of the blood flow from the heart goes to vital organs such as the brain and kidneys. Some tissues and organs have variable blood flow according to conditional demand like muscle and skin. Connective tissues receive very little blood flow. ...Read more

Cardiac Output (Definition)

Cardiac output is a measurement of the amount of blood a person's heart can pump out during a set amount of time. The measurements help doctors figure out how strong or weak ...Read more

How is cardiac output regulates central venous pressure?

How is cardiac output regulates central venous pressure?

Starling mechanism: You mean how does venous pressure regulate cardiac output.similar to the Starling mechanism-by increasing pre load. Up to a certain point cardiac output is directionally proportional to venous pressure assuming that everything else is the same such as the after load or cardiac contractility ...Read more

Which value of cardiac output is considered high?My stroke volume 90ml, by 75 bpm, that means cardiac out:6, 7l/min;cardiac index would be 3, 5l/min*m2.Tx

Cardiac Output: Numbers such as you list can be normal especially in a smoker. Numbers alone without clinical correlation don't necessarily mean a lot. You should discuss these data with the physician(s) who know you and your specifics. ...Read more

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

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

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. ...Read more

How is cardiac output regulated in the body?

How is cardiac output regulated in the body?

The old way was : Based on oxygen differences from artery to vein called the fick procedure. Then came "thermal dilution", now we can do it by echo. Just plug "cardaic output" into google to learn more. www.thepmc.org. ...Read more

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

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

What is cardiac arrhythmia? Is cardiac arrhythmia partly caused by water intoxication?

What is cardiac arrhythmia? Is cardiac arrhythmia partly caused by water intoxication?

Abnormal heartbeat: The normal heartbeat is from the sinus, located in the top of the heart and is called normal sinus rhythm. An arrhythmia is anything other than sinus rhythm - supraventricular tachycardia (svt), atrial fibrillation, atrial flutter, ventricular tachycardia are all cardiac arrhythmias. They can cause fainting and worse, up to and including death. Water intoxication does not cause them. Alcohol can. ...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

Will epinephrine increase cardiac output?

Yes: It makes the heart contract more forcefully and makes it beat faster. Both effects will increase the cardiac output. ...Read more

Clarify:cardiac output too high at rest? Echo:stroke volume 100ml by 70 bpm, that means cardiac out:7l/min; cardiac index would be 3, 57l/min*m2.Txs

Clarify:cardiac output too high at rest? Echo:stroke volume 100ml by 70 bpm, that means cardiac out:7l/min; cardiac index would be 3, 57l/min*m2.Txs

High Cardiac Output: Cardiac output is calculated by multiplying stroke volume by heart rate. Since the amount of blood pumped by the heart is dependent on body surface area ie. A larger person needs more blood supply. If it is more than 6l/min in an average person, at rest , and associated with symptoms, the cause must be looked into. ...Read more

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

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

Is my cardiac output too high? Results from echo:stroke volume 100ml, by 70 bpm, that means cardiac out:7l/min; cardiac index would be 3, 57l/min*m2.

Is my cardiac output too high? Results from echo:stroke volume 100ml, by 70 bpm, that means cardiac out:7l/min; cardiac index would be 3, 57l/min*m2.

Cardiac output: Your measured cardiac output is high for someone at rest, but not at all if you do any exertion or are under stress. Co can reach 15 l/min in healthy men without any difficulty. ...Read more

How can I find stroke volume and heart rate given cardiac output equation?

How can I find stroke volume and heart rate given cardiac output equation?

SVxHR=CO: You can count your heart rate by taking your pulse. That's the easy part. To get SV, you can do an echo to estimate it or do a right heart catheterization and perform a thermodilution and Fick measurements. (That's how cardiologists obtain it), ...Read more

If left ejection fraction is maintained in diastolic heart failure, why is the cardiac output decreased?

Think stiffness: In diastolic dysfunction, the heart muscle tends to be stiff, so that it doesn't "relax" well and fill with blood. So even if the heart can pump blood forward OK, if it doesn't fill up appropriately, then it won't function optimally ... ...Read more

Formula for cardiac output  via fick test using blood gases and hgb work in critical care?

Fick Cardiac Output: Cardiac ouput = vo2/13.4 x hb x(sao2 - svo2) vo2 = o2 consumption (~ 250 cc/min in healthy individual) hb = hemoglobin sao2 = arterial oxygen saturation svo2= venous oxygen saturation. ...Read more

What is meant by decreased cardiac output related to left ventricular failure?

Sick muscle: The heart is supposed to pump out a certain amount with every heart beat, if that amount is too low, e.g. Low out put, the heart muscle is too weak to do it's job(failure). ...Read more
