What is Cardiac Output?

Cardiac output (CO) is the measurement of blood pumped by the left ventricle of the heart in a minute. The cardiac output is calculated by the measurement of heart rate (HR) and stroke volume (SV). The cardiac output value is measured in liters (L) per minute....

Factors Affecting Cardiac Output

There are several factors determining the efficiency of cardiac output regulation of a person. The body’s demand for blood changes during heavy workouts or any physical activity. Thus the demand for blood increases the heart beat and increases the cardiac output. That is the cardiac output can be altered by the change in heart rate and stroke volume....

Cardiac Output Measurement Methods

The measurement of cardiac output is done by various invasive or non-invasive methods. Invasive methods are done by entering into the body part with the help of medical instruments while non-invasive means instruments used without breaking the skin or causing an injury. Some examples of such methods are given below:...

Cardiac Index

Cardiac index (CI) is the evaluation of cardiac output based on a person’s body size. It is calculated by dividing cardiac output by a person’s body surface area (BSA)....

What is the Significance of Cardiac Output?

The Cardiac output and Cardiac index of a person are important to know if the patient’s heart is pumping enough blood and delivering sufficient oxygen to cells....

Conclusion – Cardiac Output

The cardiac output gives the analysis of the functioning of the heart. There are various factors affecting cardiac output like age, physical activity, contractability, preload and afterload. Many techniques are used to measure the cardiac output of a person. The value cannot be excessively low or high; it should be steady. It is always better to have a healthy lifestyle with constant exercise and good dietary foods to ensure a healthy heart....
