When the low pressure is around 58 and the high pressure is 100, it is also basically normal if there is no obvious discomfort. Normal adult systolic blood pressure is generally considered to be 12 to 18.7kPa (90 to 140mmHg) and diastolic blood pressure 8 to 12kPa (60 to 90mmHg). Newborns have a systolic blood pressure of 6.7 to 8.0kPa (50 to 60mmHg) and a diastolic blood pressure of 4 to 5.3kPa (30 to 40mmHg). Human blood pressure is in a state of dynamic change and is affected by many factors, such as age and gender, environment, body position, and mental factors. The accuracy of blood pressure monitoring can also be affected by the correct or incorrect measurement method. Therefore, if a single measurement of blood pressure is 100/58 mmHg, several measurements can be taken to monitor the change in blood pressure. If the blood pressure is still slightly low after several measurements, and if there are no symptoms such as dizziness, fatigue, etc., the patient can be closely observed for the time being, and no special treatment is needed for the time being. If dizziness, fatigue and other discomforts occur, you can go to the hospital for further examination and treatment in time to avoid delaying the condition.
