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

What are the factors that affect cardiac output?

What are the factors that affect cardiac output?

Cardiac output: Stroke volume times heart rate equals cardiac output. Stroke volume relates to myocardial contractility, vascular resistance, vascular volume, anemia and metabolic state. There are subcomponents to all of these. ...Read more

What are factors that influence the cardiac output?

What are factors that influence the cardiac output?

Cardiac output: In strict physiologic terms, cardiac output is determined by something called stroke volume and heart rate. Heart rate is self-explanatory. Stroke volume is the amount of blood that the heart pumps out with each beat. This in turn is dependent on blood pressure, total blood volume, and how strong the heart contracts. ...Read more

What area of the brain has the greatest effect on visceral functions (e.g. heart rate and hormone production)?

What area of the brain has the greatest effect on visceral functions (e.g. heart rate and hormone production)?

Hormones: Please go online to Yahoo Images or something similar and look for images of the Pituitary Gland. There is usually a small comment with the images. Fell free to contact me again if there are things on the web you don't fully understand. You can of course also discuss these items with your doctor. ...Read more

In what way damage to the conduction system of the heart impact stroke volume?

In what way damage to the conduction system of the heart impact stroke volume?

Lower stroke volume: If part of your heart are not properly innervated, the muscle will not contract as needed and the stroke volume may diminish. Uneven contraction may lead to thrombus formation and potentially stroke, check with your cardiologist. ...Read more

What is the physiology underlying the changes in mean arterial pressure and heart rate that occur with changes in posture?

What is the physiology underlying the changes in mean arterial pressure and heart rate that occur with changes in posture?

Blood Fall ; Gravity: Person curious about physiologic changes in body going from supine to upright should regard faster ; more vigorous heart beats to pump blood ; oxygen to neediest tissue, the brain, which resides on highest part of the body tower. Blood column falls farther in an upright body, thereby causing arterial constriction to acutely diminish size of the blood container, the arterial system. ...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

What factors can affect the heart rate of adolescents?

What factors can affect the heart rate of adolescents?

Activity Level: The heart rate of an individual varies with activity level all through the day. The most commonly alluded to figure is the resting heart rate, which is the number of times the heart beats at per minute while the subject is at rest. In adults it averages around 72bpm, but can approach 200bpm with high level of activity. In conditioned athletes, resting heart rate could be as low as 50bpm or less. ...Read more

How is the pulse rate related to heart rate and the flow of blood in someone?

How is the pulse rate related to heart rate and the flow of blood in someone?

Same: Pulse rate and heart rate are the same generally...This occurs when blood is ejected from the left ventricle to the systemic arterial circulation. There are rare instances when a premature beat comes so close ti last beat that a strong pulse is not transmitted but this is rare. ...Read more

What is the relation of hypertension and decreased cardiac output?

What is the relation of hypertension and decreased cardiac output?

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 percentage of cardiac output delivered to the heart?

What is the percentage of cardiac output delivered to the heart?

About 4%: About 4% of the cardiac output goes to the heart muscle itself. That is the same either at rest or with exercise. ...Read more

How does increase amount of the carbon dioxide in the blood affect kidney and causes renal failure?

How does increase amount of the carbon dioxide in the blood affect kidney  and causes renal failure?

Carbon Dioxide : Good question. Your kidneys have many functions. One is to maintain ph balance. When your body accumulates too much carbon dioxide(co2) your kidneys work to eliminate it. Co2 makes your body more acidic. The acidity not only makes your kidneys work harder, but it also makes all body functions less efficient. Over time this can cause kidney failure. This is not a common cause of kidney failure. ...Read more

How can the change in posture affect on cardiac output ?

How can the change in posture affect on cardiac output ?

Posture does affect: With standing, blood pressure drops a little, and this is augmented by an increased HR. Over, Cardiac output stays the same overall. However, in heart failure, output can drop with changes of position and exertion. ...Read more

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

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

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

How can high levels of cholesterol in the blood affect the heart to function?

How can  high levels of cholesterol in the blood affect the heart to function?

With time: High levels of LDL and low levels HDL may form an atheromatous plague at your coronary arteries creating a stenosis and an ischemic heart disease with high risk for a heart attack. Depending on family history and other risk factors you chances can get very high. Lifestyle changes early and possibly treating increase chol may prevent the disease. Good luck. ...Read more
