In a 21 year old patient, the standard systolic blood pressure range is 100-120 mmHg and the standard diastolic blood pressure range is 60-80 mmHg. If the patient’s current blood pressure stays below 130/80 mmHg, it is relatively the ideal blood pressure. If the patient currently has an abnormal blood pressure and would like to be further evaluated for hypertension or hypotension. It is recommended that the patient undergoes 3 measurements on different days, or that the patient undergoes ambulatory blood pressure monitoring. This test is the preferred method in clinical practice because it can more objectively assess the patient’s overall blood pressure over a 24-hour period, which helps to confirm whether the patient is hypertensive or hypotensive, and it is recommended that the patient maintains a normal lifestyle while undergoing this test.
