Verified step by step guidance

Understand the concept of cardiac output: Cardiac output is the volume of blood the heart pumps per minute. It is a crucial measure of heart function and overall cardiovascular health.

Identify the components involved in calculating cardiac output: The two main components are Heart Rate (HR), which is the number of heartbeats per minute, and Stroke Volume (SV), which is the amount of blood pumped by the heart with each beat.

Recognize the correct relationship between these components: Cardiac Output (CO) is calculated by multiplying Heart Rate (HR) by Stroke Volume (SV). This relationship is expressed as CO = HR × SV.

Evaluate the given options: Compare each option to the correct formula CO = HR × SV. The correct formula should reflect the multiplication of Heart Rate and Stroke Volume.

Select the correct formula: Based on the understanding that cardiac output is the product of heart rate and stroke volume, identify the option that matches CO = HR × SV as the correct formula.
