Pulse pressure is defined as

Pulse pressure is defined as

• A. The difference between systolic and diastolic pressure in the arteries
• B. The average of systolic and diastolic pressure
• C. The sum of systolic and diastolic pressure
• D. The diastolic pressure alone

Answer: (A)

Pulse pressure is the difference between the pressure in the arteries when the heart beats (systolic) and when the heart rests between beats (diastolic). It is calculated by subtracting diastolic pressure from systolic pressure, so for a reading like 120/80, the pulse pressure is 40 mmHg. This value reflects the pressure change the arterial system undergoes with each heartbeat and provides insight into stroke volume and arterial compliance. A larger pulse pressure can indicate stiffer arteries or a high stroke volume, while a smaller pulse pressure may point to low stroke volume or other issues affecting blood flow. It is not the average of the two pressures, nor their sum, nor is it just the diastolic pressure.
