If the systolic pressure is `120 mm` Hg and diastolic pressure is `80 mm` Hg the pulse prssure is `............`

Options

A. `120xx80 = 9600 "mmHg"`
B. `120+80=200"mmHg"`
C. `120-80 =40 "mmHg"`
D. `(120)/(80)=1.5"mmHg"`

Answer

To find the pulse pressure, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definitions**:
- **Systolic Pressure**: This is the pressure in the arteries when the heart beats (contracts).
- **Diastolic Pressure**: This is the pressure in the arteries when the heart is at rest (between beats).
- **Pulse Pressure**: This is the difference between systolic and diastolic pressure.

2. **Identify the Given Values**:
- Systolic Pressure = 120 mm Hg
- Diastolic Pressure = 80 mm Hg

3. **Use the Formula for Pulse Pressure**:
- The formula for calculating pulse pressure is:
\[ \text{Pulse Pressure} = \text{Systolic Pressure} - \text{Diastolic Pressure} \]

4. **Substitute the Values into the Formula**:
- Substitute the given values into the formula:
\[ \text{Pulse Pressure} = 120 \, \text{mm Hg} - 80 \, \text{mm Hg} \]

5. **Perform the Calculation**:
- Calculate the difference:
\[ \text{Pulse Pressure} = 40 \, \text{mm Hg} \]

6. **State the Final Answer**:
- The pulse pressure is **40 mm Hg**.
