Article in English: Sit down at a table or desk where you can easily set up the necessary equipment. Remove the cuff, stethoscope, pressure gauge, and bulb from the kit, taking care to untangle the various tubes. Elevate your arm so that when you bend your elbow, your elbow is parallel to your heart. This ensures that you will not get either an overestimated or underestimated reading on your blood pressure. It is also important that your arm is supported during the reading, so make sure to rest your elbow on a stable surface. Most cuffs have Velcro, making it easy to secure the cuff in place. If your shirt has long or thick sleeves, roll them up first, as you can only put the cuff over very thin clothing. The bottom edge of the cuff should be about an inch above the elbow. Some experts recommend you use your left arm; others suggest you test both arms. But while you're first adjusting to self-testing, use the left arm if you're right-handed, or vice versa. If the cuff is too loose, the cuff will not compress the artery correctly, giving you an inaccurately low blood pressure reading. If the cuff is too tight, it will create what is known as "cuff hypertension" and give you an inaccurately high reading. Cuff hypertension can also occur if the cuff is too narrow or too short relative to your arm. The head of the stethoscope (also known as the diaphragm) should be placed flat against the skin on the inside of your arm. The edge of the diaphragm should be just beneath the cuff, positioned over the brachial artery. Gently put the earpieces of the stethoscope in your ears.  Do not hold the head of the stethoscope with your thumb — your thumb has its own pulse and this will confuse you while you try to obtain a reading. A  good method is to hold the head of the stethoscope in place with your index and middle fingers. This way, you should not hear a thumping sound until you have begun to inflate the cuff. If the pressure gauge is clipped to the cuff, unclip it and attach it to something sturdy instead, such as a hardcover book. That...
