You can easily obtain the most authentic results if you follow a few simple key instructions. If you use your sphygmomanometer daily, attempt to make it a standard habit of yours to use the machine at around the same time every day to avoid the normal variations in our blood pressure throughout the day. Secondly, avoid smoking, caffeine, exercising, and showering up to half an hour before the test. In the minutes leading up to your test, try your best to relax and stay calm. During the test itself, sit up straight with your left arm at your heart’s level, resting on a hard surface with your palm to the sky and your legs uncrossed. Breathe normally and without any special effort, and simply do not talk nor move during the test. With these simple rules, you are bound to get the most accurate results!
