Normal pulse pressure is

Options

A. 80 mm Hg
B. 120 mm Hg
C. 40 mm Hg
D. 320 mm Hg

Answer

### Step-by-Step Solution:

1. **Understanding Blood Pressure**: Blood pressure is measured using two values: systolic pressure (the top number) and diastolic pressure (the bottom number).

2. **Defining Systolic Pressure**: Systolic pressure is the pressure exerted by the heart when it beats. This is the maximum pressure in the arteries.

3. **Defining Diastolic Pressure**: Diastolic pressure is the pressure in the arteries when the heart is at rest between beats. This is the minimum pressure in the arteries.

4. **Normal Values**: The normal systolic pressure is typically around 120 mmHg, and the normal diastolic pressure is around 80 mmHg.

5. **Calculating Pulse Pressure**: Pulse pressure is calculated by subtracting diastolic pressure from systolic pressure.
- Formula: Pulse Pressure = Systolic Pressure - Diastolic Pressure
- Calculation: Pulse Pressure = 120 mmHg - 80 mmHg = 40 mmHg.

6. **Conclusion**: Therefore, the normal pulse pressure is 40 mmHg.

### Final Answer:
Normal pulse pressure is **40 mmHg**.
