Pulse pressure is

Options

A. Volume of blood pumped out by heart with one beat
B. Systolic minus diastolic blood pressure
C. Gap between auricular systole and ventricular systole
D. Equal to diastolic blood pressure

Answer

**Step-by-Step Text Solution:**

1. **Understanding Pulse Pressure**: Pulse pressure is a term used in cardiovascular physiology to describe the difference between two specific blood pressure measurements: systolic and diastolic blood pressure.

2. **Identifying Systolic and Diastolic Blood Pressure**:
- **Systolic Blood Pressure**: This is the pressure in the arteries when the heart beats and pumps blood.
- **Diastolic Blood Pressure**: This is the pressure in the arteries when the heart is at rest between beats.

3. **Calculating Pulse Pressure**:
- The formula to calculate pulse pressure is:
\[ \text{Pulse Pressure} = \text{Systolic Blood Pressure} - \text{Diastolic Blood Pressure} \]

4. **Evaluating the Options**:
- **Option 1**: "The volume of blood pumped out by heart with one beat."
- This is incorrect because this describes stroke volume, not pulse pressure.
- **Option 2**: "Systolic minus diastolic blood pressure."
- This is correct as it directly defines pulse pressure.
- **Option 3**: "Gap between auricular systole and the ventricular systole."
- This is incorrect as it does not relate to pulse pressure.
- **Option 4**: "Equals to the diastolic blood pressure."
- This is incorrect because pulse pressure is not equal to diastolic blood pressure.

5. **Conclusion**: The correct answer is Option 2, which states that pulse pressure is the difference between systolic and diastolic blood pressure.
