What is the normal diastolic blood pressure range?

The normal diastolic blood pressure range is considered to be between 60 and 80 mmHg for healthy adults. Choosing the range of 60 to 90 mmHg aligns with this understanding, as it encompasses the lower end of normal diastolic pressure while also allowing for some variations that might be observed in different individuals.

Diastolic blood pressure reflects the pressure in the arteries when the heart is resting between beats. Maintaining a diastolic pressure within the normal range is crucial for ensuring that organs receive adequate blood flow and oxygenation. Consistently higher or lower levels can indicate underlying health issues, which is why recognizing the normal range is important for patient assessment and care.

The other ranges provided either fall too low or too high for normal diastolic blood pressure. A range of 40 to 60 mmHg is typically considered too low, indicating potential hypotension. A range of 90 to 100 mmHg or above is generally categorized as elevated or hypertensive, which could signify potential cardiovascular problems. Thus, the chosen range effectively summarizes the expected parameters for a healthy diastolic pressure.
