What is the difference between systolic and diastolic pressure known as?

The difference between systolic and diastolic pressure is known as pulse pressure. This term is significant because it reflects the force that the heart generates each time it contracts and offers insight into the condition of the arteries. More specifically, pulse pressure can indicate the health of the cardiovascular system; a wider pulse pressure may suggest increased stiffness of the arteries, potentially leading to cardiovascular risk.

In contrast, the other terms presented do not accurately describe this specific measurement. "Blood pressure gradient" does not specifically refer to the difference between systolic and diastolic pressures in a way that is clinically recognized or defined. "Systolic difference" and "diastolic variability" are phrases that don't correspond to established terminology used in the assessment of blood pressure. Understanding pulse pressure is crucial for nursing practice, as it allows healthcare professionals to monitor and interpret cardiovascular health effectively.
