The normal blood pressure range of human body is 60-90mmHg diastolic and 90-140mmHg systolic, i.e. low pressure is 60-90mmHg and high pressure is 90-140mmHg, so low pressure 88mmHg and high pressure 120mmHg is not serious and within the normal range. For this type of blood pressure state usually does not require intervention and treatment, and it is recommended that regular blood pressure testing be performed on a regular basis. Blood pressure should be measured with 5-10 minutes of rest in a quiet state. It is recommended to use an arm blood pressure monitor, which will be more accurate, and continuous blood pressure monitoring is needed to assess the overall blood pressure status; transient high or low blood pressure is not clinically meaningful and there may be measurement errors or interference from other factors. When the true blood pressure status is known through multiple blood pressure measurements, it can be compared with the normal reference value to determine whether the blood pressure requires further intervention and management. If the blood pressure exceeds 140/90 mmHg, hypertension should be considered, at which point a systematic examination and standardized treatment should be performed to lower the blood pressure, as well as reduce the risk of cardiovascular disease. For normal blood pressure, there is no need for too much treatment, just regular review, regular monitoring and observation of blood pressure fluctuations.
