3.1.2 Cardiac Output/ABI Intro

Front

What is cardiac output?

Back

The amount of blood pumped by the heart each minute.

Front

How is cardiac output calculated?

Back

Cardiac output is calculated as the product of heart rate (beats per minute) and stroke volume (milliliters per beat).

Front

What is stroke volume?

Back

The volume of blood pumped out of the heart in each beat.

Front

What factors can influence cardiac output?

Back

Body size, aerobic fitness level, and heart rate.

Front

What is the normal range for stroke volume in a healthy adult?

Back

Typically between 60 to 100 milliliters per beat.

Front

If a performer has a heart rate of 150 bpm and a stroke volume of 80 ml, what is their cardiac output?

Back

12.0 liters per minute or 12,000 ml per minute.

Front

Where is the dorsalis pedis pulse located?

Back

On the top of the foot.

Front

What does a high stroke volume indicate?

Back

It indicates that the heart is pumping a larger volume of blood with each beat, often associated with good cardiovascular fitness.

Front

What is the relationship between heart rate and cardiac output?

Back

As heart rate increases, cardiac output typically increases, assuming stroke volume remains constant.

Front

What does it mean if cardiac output is low?

Back

It may indicate poor heart function or inadequate blood flow to meet the body's needs.
