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

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?

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 influences cardiac output?

Multiple things: Cardiac output is the product of heart rate in stroke volume. Thus, an increase in heart rate results in an increase in cardiac output. Stroke volume can be affected by changes in preload, afterload, and contractility (strength of contraction). Preload is "priming the pump". Afterload is the resistance to ejection during systole (contraction). ...Read more

What are ?Influences that can alter cardiac output?

What are ?Influences that can alter cardiac output?

In general four: Cardiac output is influence by the amount of blood the heart recieves,the resistance against which the blood is ejected,the strength of contraction and the heart rate. For ex. CO increases with heart rate,increase in blood volume,increase in cardiac contraction and less resistance to ejection because of lower peripheral resistance. Clinical conditions that affects any 4 will alter cardiac output ...Read more

What's cardiac output?

Heart pump volume: The cardiac output is the volume of blood per minute pumped by the heart. Cardiac output is equal to heart rate multiplied by stroke volume (the volume of blood ejected with each heartbeat). ...Read more
