How is pulse pressure calculated correctly?

Pulse pressure is an important cardiovascular measurement that reflects the difference between the systolic and diastolic blood pressure readings. It is calculated by subtracting the diastolic pressure from the systolic pressure. This value provides insight into the force that the heart generates with each contraction and can indicate the health of the arteries.

The correct answer focuses on this fundamental aspect of blood pressure readings, highlighting the importance of the difference between the two measurements. A wider pulse pressure can signify various health conditions, including those affecting cardiovascular health.

Other methods mentioned in the options, such as averaging or adding the systolic and diastolic pressures, do not provide accurate assessments of the pulse pressure and are therefore not suitable for this calculation. Converting measurements to mmHg is also irrelevant, as pulse pressure is inherently expressed in mmHg and does not require conversion.
