In general, a systolic blood pressure of 108 mmHg and a diastolic blood pressure of 65 mmHg are considered normal. Blood pressure is the basic vital signs of the human body, under physiological conditions, the human blood pressure fluctuates within a certain range. Normal systolic blood pressure ranges from 90 to 139 mmHg, and normal diastolic blood pressure ranges from 60 to 89 mmHg. Therefore, a systolic blood pressure of 108 mmHg and a diastolic blood pressure of 65 mmHg are considered normal. However, to evaluate whether an individual’s blood pressure is normal or not, it is important to consider not only whether it is in the normal range, but also to use the patient’s baseline blood pressure as a reference. For the elderly and frail, or for those with severe stenosis of arteries supplying vital organs (e.g., the brain), maintaining blood pressure at a lower level within the normal range may reduce blood perfusion to vital organs and affect the patient’s health. Patients’ blood pressure is affected by a variety of factors and there is individual variability. Whether the blood pressure is normal or not should be measured and evaluated by a physician in a standardized manner.
