What is measured when assessing diastolic pressure?

When assessing diastolic pressure, the value measured is the constant pressure in the arteries when the heart is at rest between beats. This is the phase in the cardiac cycle when the heart relaxes after contracting and filling with blood, indicating the pressure that remains in the arteries, allowing blood to flow to the tissues.

Diastolic pressure is important because it reflects the minimal arterial pressure and is crucial for understanding the overall health of the cardiovascular system. Elevated diastolic pressure can indicate hypertension, while abnormally low diastolic pressure could suggest other health issues.

Understanding this concept is vital in health science as it helps provide insights into a patient's heart health and potential risks for cardiovascular disease.
