There are several reasons why you may have inconsistent readings. Many factors exist that can cause a variation in blood pressure measurement values, for example, recent activities or even the time of day can alter the reading.
Additionally, the user’s technique is very important for reliable measurement results. Listed below are some of the common reasons you may get an inconsistent or inaccurate reading:
Measure the circumference of your arm. Make sure the arm cuff you are using with your monitor is the correct size for you. When the incorrect cuff is used you may get an inaccurate reading at the first measurement you take or after a short period of use because the cuff bladder will be damaged. To determine your arm size, use a cloth tape measure and place midway between your elbow and your shoulder around the circumference of your upper arm. Wrap the tape measure evenly around your arm. Do not pull the tape tight.
Make sure you are wrapping the cuff around your arm in the correct position. After wrapping the cuff around your arm check the location of the brachial artery marker. The air tube should run down the centre of your arm. The cuff should not be wrapped too tight or too loose.
Before Taking a Measurement
Avoid eating, drinking alcohol, smoking, exercising, and bathing for 30 minutes and rest for 15 before starting the measurement. Avoid taking a measurement during stressful times. Take the measurement in a quiet place.
Sit in a chair with your feet flat on the floor. Rest your arm on a table with your palm facing upward. The cuff should be level with your heart. Do not talk or move during the measurement.
