Question: Which of the following factors can increase cardiac output?

Options:

Correct Answer: Increased heart rate

Solution:

Increased heart rate can lead to an increase in cardiac output, as cardiac output is the product of heart rate and stroke volume.

Which of the following factors can increase cardiac output?

Which of the following factors can increase cardiac output?

Step 1: Understand what cardiac output is. Cardiac output is the amount of blood the heart pumps in one minute.
Step 2: Know the two main components of cardiac output: heart rate (how many times the heart beats in a minute) and stroke volume (the amount of blood pumped with each beat).
Step 3: Remember the formula for cardiac output: Cardiac Output = Heart Rate x Stroke Volume.
Step 4: Realize that if you increase the heart rate, while keeping stroke volume the same, the cardiac output will increase.
Step 5: Consider other factors that can also increase stroke volume, such as exercise or increased blood volume, which can also lead to higher cardiac output.
