Knowing how to properly take your blood pressure is vital, especially if you suffer from hypertension (high blood pressure) and need to consistently monitor your condition. Hypertension is known as the silent killer because you may show no symptoms, yet suddenly experience a heart attack. There is a right and wrong way to take your blood pressure and knowing the difference can make the difference when it comes to your health and well-being.
How to Take Blood Pressure Readings in the Arms
Step 1
Choose an arm. When taking a blood pressure, especially on a regular basis, it is important to use the same arm each time; a blood pressure reading can vary by 10 points between arms.
When choosing the arm you will use, take into account that the left arm is better because it is closer to your heart. However if paralysis exists, it can interfere with the accuracy of your reading, so the opposite arm should be used.
Step 2
Find your pulse. Using your forefinger and middle finger, locate the brachial pulse found in the bend of your arm.
Step 3
Determine the cuff needed. In most cases, an average adult cuff will work, though an extra-large cuff may be needed if you are obese. If you are not using the proper-size cuff, your reading will be inaccurate.
Test the size by wrapping the cuff snugly around your arm. It should overlap a little. If it does not, or you struggle to tighten the cuff, you need to use a larger one.
Step 4
Wrap the cuff. Straighten your arm until fully extended, making sure it is level with your heart. For the most accurate reading, your arm should be placed on a firm object such as a table or stand.
Wrap the cuff around your upper arm. The bottom of the cuff should be an inch above the bend of your arm. The rubber insert of the cuff should be in line with your brachial pulse. Place the round end of the stethoscope over your pulse.
Step 5
Begin inflating. Turn the air valve attached to the squeezable bulb away from you until it stops. This tightens the valve, allowing you to inflate the cuff with air. Pump the bulb until the dial on the cuff reads 180.
Step 6
Deflate the cuff. Turn the air valve slightly toward you, slowly releasing the air in the cuff. Watch the dial on the cuff and listen closely through the stethoscope for the first beat. The number you see when the first beat is heard is the systolic blood pressure. Continue listening and watching; the beats will begin to sound fainter. The number you see when the last beat is heard is the diastolic blood pressure.
