Introduction
To ensure accurate readings from an electronic blood pressure monitor, it is important to choose the correct measurement time and physical condition, select the appropriate measurement site and posture, use the cuff correctly, follow proper measurement methods, and take repeated measurements to calculate an average value. When selecting an electronic blood pressure monitor, one should also choose a product that meets relevant standards and has reliable quality to ensure measurement accuracy.
To ensure accurate readings from an electronic sphygmomanometer, it is important to choose the correct measurement time and state, select the proper measurement site and posture, use the cuff correctly, follow the correct measurement method, and repeat measurements and take the average value. The details are as follows:
1. Choose the Correct Measurement Time and State
Before measuring blood pressure, ensure you have rested adequately. Avoid measuring immediately after strenuous exercise, stress, or emotional fluctuations. It is recommended to rest for 10–15 minutes before taking the measurement. The best time for measurement is within one hour after waking up in the morning or before going to bed at night, as blood pressure tends to be relatively stable during these periods.
2. Choose the Correct Measurement Site and Posture
When using an upper-arm electronic blood pressure monitor, select the brachial artery of the upper limb as the measurement site, as blood pressure readings obtained at this location are generally more accurate. Sit in an upright position with your body relaxed, arm naturally extended, palm facing upward, and elbow resting flat on a tabletop. The cuff should be positioned at the same level as the heart.
3. Use the Cuff Correctly
Select an appropriately sized cuff based on the subject's arm circumference, as a cuff that is too tight or too loose may affect the measurement accuracy. The cuff should be wrapped smoothly around the middle of the upper arm, avoiding the elbow joint. Ensure that the midpoint of the cuff's vertical height aligns with the level of the heart.
4. Follow the Correct Measurement Method
Operate the electronic blood pressure monitor according to the manufacturer's instructions to avoid incorrect operation during measurement. Maintain normal breathing throughout the measurement and avoid talking as much as possible, as this may interfere with the measurement results.
5. Repeat Measurements and Take the Average
For each measurement session, it is recommended to repeat the measurement three times and take the average value as the final result. There should be an interval of at least 3 minutes between consecutive measurements to ensure accuracy.
In addition, when selecting an electronic blood pressure monitor, make sure to choose a product that meets relevant standards and is of reliable quality to ensure measurement accuracy.
