Q:Assuming one has a good monitor and takes multiple readings throughout the day, the range of readings may well vary from the 120/80 region or below to 128/85 or above. The range depends on time of day and medication period. So what would a reasonable target range be? Yes, I know the answer has to be “it depends on the patient”, but are there at least guidelines?
A:Blood pressure varies throughout the day. It is not constant. However your blood pressure should stay within the normal range. Your blood pressure should be below 140/90 whenever you take a measurement. If you are getting a blood pressure reading consistently above 139/89, you need to talk to your doctor about changing your treatment. The change could be as simple as changing when you take your medication.
