Verified step by step guidance

Step 1: Understand the formula for cardiac output. Cardiac output (CO) is calculated using the formula: CO = Heart Rate (HR) × Stroke Volume (SV).

Step 2: Identify the given values in the problem. The heart rate (HR) is 60 beats per minute (bpm), and the stroke volume (SV) is 90 mL per beat.

Step 3: Substitute the given values into the formula. Replace HR with 60 bpm and SV with 90 mL in the equation CO = HR × SV.

Step 4: Perform the multiplication to calculate the cardiac output. Multiply 60 bpm by 90 mL to determine the total volume of blood pumped per minute.

Step 5: Express the result in the appropriate units. Since stroke volume is given in milliliters (mL), the cardiac output will be expressed in mL/min.
