Pulse pressure is defined as which of the following?

Pulse pressure is defined as which of the following?

• A. Systolic minus diastolic
• B. Diastolic minus systolic
• C. Average of systolic and diastolic
• D. Sum of systolic and diastolic

Answer: (A)

Pulse pressure is the pressure change in the arteries with each heartbeat, defined as systolic pressure minus diastolic pressure. This difference reflects the force the heart generates during contraction and how stretchy the arteries are. For a typical reading like 120/80, the pulse pressure is 40 mmHg. The other ideas don’t describe this swing: subtracting diastolic from systolic would give a negative value in some cases and isn’t the standard measure; averaging systolic and diastolic gives a mid-point pressure, not the pressure difference; and summing the two pressures has no direct interpretation for the pulse swing. Understanding pulse pressure helps interpret cardiovascular status: a wide pulse pressure suggests large swings and can indicate arterial stiffness or high stroke volume, while a narrow pulse pressure can point to low stroke volume or acute illness.
