First, read the English article below.

Taking a traditional blood pressure measurement with a blood pressure cuff, stethoscope, and analog sphygmomanometer can take some practice and requires instruction and experience. Some people visit automated machines at their local pharmacy in order to get their blood pressure taken.  It can be quite difficult to take your own blood pressure if you are using the traditional method. If possible, get a someone to help and take your blood pressure for you. When purchasing an at-home blood pressure monitor, make sure that the cuff (the part that goes around your arm) fits you appropriately, that you can read the monitor easily, and that it is affordable. Many insurance plans will help pay for blood pressure monitoring machines. Most of these machines are automated. You simply put on the cuff, hit start and wait for your results.  Avoid sugars, caffeine, and excessive stress before taking your blood pressure. These three triggers will elevate your blood pressure and give you a false reading. If you insist on taking your own blood pressure at home, do so three times in order to make sure that you are doing it right. Make sure that you are comfortably seated, relaxed, and have your arm at or near your heart level. If you notice that each reading is higher than the last, allow a little more time between readings. It is important to note that most machines need to be calibrated. In order to know if a device is accurate, it should be checked at the doctor's office once per year and compared to their blood pressure monitor for accuracy. Say 110/68 is your blood pressure reading. It is a good idea to record these numbers somewhere so you can keep track of your blood pressure fluctuations. Since your blood pressure can fluctuate throughout the day, you'll want to take multiple readings at different times throughout the day (over the course of two to three weeks for the most accuracy) and average these readings. In this example, you’d subtract 68 from 110. Your pulse pressure would be 42.
