However, many people still perform it incorrectly, leading to inaccurate results, causing misunderstandings about their health status.
One of the common mistakes is measuring blood pressure immediately after exercise, drinking coffee or smoking. These factors can cause blood pressure to temporarily increase, making the index higher than reality. In addition, incorrect sitting posture such as crossing legs, not leaning back, or hand not placing across the heart also significantly affects the measurement results.
According to the American Heart Association, patients need to rest for at least 5 minutes before measuring blood pressure and should measure it in quiet conditions to ensure accuracy. The organization emphasizes: "Posture error or psychological stress can significantly distort blood pressure levels.
Another mistake is measuring at the wrong time or only measuring once. Experts recommend measuring at the same time each day, usually in the morning and evening, while measuring 2-3 times and taking the average value to monitor more accurately.
In addition, using an inappropriate measuring device or not checking the device periodically can also distort the results. Users should choose a standard and periodically calibrated biceps machine.
Doctors recommend that home blood pressure measurement is only really effective when patients perform the correct technique and maintain it regularly. If blood pressure levels fluctuate abnormally or for a long time, they need to go to a medical facility for assessment and timely treatment.
