    You can get an accurate blood pressure reading with these tips:
    • Don't have coffee (or any form of caffeine) and don't smoke 30 minutes before a reading.
    • Don't talk or eat while you check.
    • Sit with your back supported and both feet on the floor.
    • Get the cuff on your bare arm, not over your sleeve.
    • Take more than one reading, especially if you get unusual numbers. All kinds of factors, from exercise to cold weather, can throw your blood pressure off.

    Before your blood pressure is measured, sit for five minutes. Then, your arm should be stretched out at heart level. Your feet should be on the floor and you should be leaning back. The blood pressure monitor cuff should be doubled around your upper arm, covering 80% of it. If the cuff is smaller, your blood pressure may measure higher than it really is. If you buy an electronic device for home, for best results, choose the one that fits over the elbow. Refrain from coffee, tea or cigarettes for 30 minutes before the test.

    When you monitor your own blood pressure at home, which you must if you are on blood pressure medication, here are some tips to help ensure an accurate reading:
    • Avoid caffeine and smoking for 30 minutes prior to taking your blood pressure.
    • Sit quietly (don’t talk) with both feet flat on the floor for at least three minutes before you inflate the cuff. It is important to feel relaxed when your blood pressure is taken because stress raises your blood pressure.
    • Avoid certain foods and activities prior to taking your blood pressure. Please, don’t take your blood pressure after you’ve gulped down a coffee, eaten a meal or had a bowel movement. A blood pressure reading taken shortly after any one of these actions will most likely be higher.
    • Use your right arm for blood pressure readings, unless there is a medical reason not to, such as an injury, weakness, recent procedure or breast surgery with lymph node removal.
    • Wait at least two minutes between readings or the second reading may be inaccurate.
    Remember: If you are taking blood pressure medication that is not working as you know it should, get medical help. A blood pressure reading of 180/110 is a medical emergency!

    To get an accurate blood pressure reading, make sure you have been sitting for several minutes. The arm should be outstretched with the appropriate-sized blood pressure cuff. A blood pressure cuff that measures at the wrist isn’t trustworthy; blood pressure reading should be taken above the elbow.

    It’s vital that blood pressure measurement is accurate. You don’t want your blood pressure treatment to be based on incorrect measurements. Here are some tips to ensure you get the most accurate readings possible:
    • Use a blood pressure machine that’s been compared to the one used in your healthcare provider’s office. To continue to ensure accurate home blood pressure measurements, have your healthcare provider check your monitor about every six months. If you drop the monitor, or readings change abruptly, have it checked right away.
    • Try to get readings at a consistent time each day--usually morning or evening. Your blood pressure can fluctuate by 20-30 mmHg at various times of the day and can change based on what you’re doing.
    • Don’t take your blood pressure within a half hour of eating a heavy meal, drinking caffeine, exercising, or using tobacco products. These things can temporarily raise your blood pressure.
    • Remove jewelry or clothing that interferes with cuff placement.
    • Make sure the blood pressure cuff is the correct size for your arm, and that it’s positioned correctly with no wrinkles in the cuff.
    • Sit quietly for 5 minutes or more, with both feet flat on the floor, before taking your blood pressure. If possible, rest your arm at heart level on a table or arm of a chair.
    • Take 3 readings about 5 minutes apart.
