What would be the cardiac output of a person having 72 heart beats per minute and a stroke volume of 50 mL ?

Options

A. 360 mL
B. 3600 ml
C. 7200 ml
D. 5000 ml

Answer

To calculate the cardiac output of a person, we can use the formula:

**Cardiac Output (CO) = Heart Rate (HR) × Stroke Volume (SV)**

### Step 1: Identify the given values
- Heart Rate (HR) = 72 beats per minute
- Stroke Volume (SV) = 50 mL

### Step 2: Substitute the values into the formula
Using the formula for cardiac output:
\[ CO = HR \times SV \]
Substituting the values we have:
\[ CO = 72 \, \text{beats/min} \times 50 \, \text{mL} \]

### Step 3: Perform the multiplication
Now, we will calculate:
\[ CO = 72 \times 50 \]
Calculating this gives:
\[ CO = 3600 \, \text{mL/min} \]

### Step 4: Interpret the result
The cardiac output of the person is 3600 mL/min, which can also be expressed as 3.6 liters/min.

### Step 5: Choose the correct option
From the options provided:
- 360 mL
- 3600 mL
- 7200 mL
- 5000 mL

The correct answer is **3600 mL**.

### Final Answer
**Cardiac Output = 3600 mL/min**
