Things to Consider Before Purchasing

More and more professional organizations are now recommending home blood pressure monitoring since it gives a lot more information in comparison to sporadic readings taken during the visit to a doctor. Moreover, home monitoring helps to identify masked blood pressure, it helps to avoid the white coat syndrome, and it also provides information regarding daily fluctuations.

Although home blood pressure monitors are easy to use and accurate, there is still a need to know a few things about getting perfect results.

  • First and foremost, cho0se a blood pressure monitoring device of a reputed manufacturer that has been validated in clinical studies, and is well calibrated.
  • Another thing is to make sure that the cuff is of proper size. Cuff should not be too loose or tight.

How to get accurate blood pressure readings with Omron 7121J

Next step is learning the proper method of measuring blood pressure. It is ideal to take your blood pressure twice a day. Good time to measure blood pressure is some time after waking, but before morning exercise, tea, or coffee. One can take a second reading during the day to see how the daily stress affects the blood pressure. Whenever you take a reading, just ensure that you are in a relaxed mood.

When measuring blood pressure do not smoke, do not drink coffee, take BP at least 30 minutes after the physical exertion or exercise. Once a person has identified the right time of taking BP, one should learn the correct posture while monitoring blood pressure. Make sure that you are sitting in a relaxed mood, and your arm is at the heart’s level, legs are not in cross position, and the placement of cuff just above the bend of the elbow.

For precise reading and for the sake of accurate comparison, make a habit of monitoring the blood pressure at the same time on a daily basis. Also, make a habit of keeping the record, these days using mobile apps may be an excellent option.

What if you get an unusually high reading using Omron HEM 7121J BP Monitor?

A single reading of high blood pressure is not a reason for alarm unless it is above 180/120 mm Hg. If you have slightly elevated BP than usual, just relax for a few minutes. Then take a second reading to confirm the results. However, if the reading is above 180/120 mm Hg and you are feeling uneasy, then it is the reason for concern, it is a reason to seek immediate medical help.

Accuracy of Omron HEM 7121J BP Monitor

Yes, Omron 7121J monitors are highly accurate, though some devices may have manufacturing defects and so on. If you feel that your monitor continually provides high or low reading, then it would be better to take it to your physician’s office for comparison and confirmation of accuracy.

Can Omron BP Machine 7121J make errors in certain conditions?

Omron 7121J monitor will provide an accurate reading in more than 99% of cases. In certain conditions, they are less precise than non-automated systems. We do not recommend these devices for people with cardiac arrhythmias or defects of heart rhythm.
