Difference between systolic and diastolic blood pressure is

Options

A. Blood pressure
B. Pulse pressure
C. Cardiac output
D. Pulse

Answer

**Step-by-Step Solution:**

1. **Understanding Blood Pressure**: Blood pressure is the force exerted by circulating blood on the walls of blood vessels, particularly arteries. It is measured in millimeters of mercury (mm Hg).

2. **Defining Systolic and Diastolic Pressure**:
- **Systolic Blood Pressure (SBP)**: This is the pressure in the arteries when the heart beats and pumps blood. It is the higher number in a blood pressure reading.
- **Diastolic Blood Pressure (DBP)**: This is the pressure in the arteries when the heart is at rest between beats. It is the lower number in a blood pressure reading.

3. **Calculating Pulse Pressure**: The difference between systolic and diastolic blood pressure is known as pulse pressure. It can be calculated using the formula:
\[ \text{Pulse Pressure} = \text{Systolic Blood Pressure} - \text{Diastolic Blood Pressure} \]

4. **Example Calculation**:
- If the systolic blood pressure is 110 mm Hg and the diastolic blood pressure is 80 mm Hg, then:
\[ \text{Pulse Pressure} = 110 \, \text{mm Hg} - 80 \, \text{mm Hg} = 30 \, \text{mm Hg} \]

5. **Conclusion**: The difference between systolic and diastolic blood pressure is referred to as pulse pressure, which in the example provided is 30 mm Hg.
