Is the blood pressure measured accurately by the physical examination app

The accuracy of blood pressure measurement by the physical examination treasure needs to be judged based on the quality of the equipment and the method of use. In most cases, it can be used as a reference for daily monitoring, but it cannot completely replace professional medical equipment.

Home electronic blood pressure monitors such as the Health Examination Treasure use the oscilloscope method to measure blood pressure, and their accuracy is affected by factors such as device calibration status, cuff wearing position, and measurement posture. Qualified products certified by the national medical device certification can control systolic blood pressure errors within the range of 5-10 mmHg and diastolic blood pressure errors between 3-5 mmHg when operated correctly. When measuring, one should maintain a sitting posture with the back straight and the cuff level with the heart. Before measuring, sit quietly for 5 minutes to avoid interference from exercise or diet. Some high-end models are equipped with intelligent pressurization technology and multiple measurement averaging function, which can further improve data reliability.

However, the physical examination kit has certain limitations. Patients with arrhythmia may experience significant measurement deviations, and mismatched cuff size and arm circumference can lead to increased errors. Some low-priced products have insufficient sensor accuracy, which may result in calibration deviation after long-term use. For special populations such as hypertensive patients, pregnant women, and situations where medication dosage needs to be adjusted, the measurement results of hospital mercury sphygmomanometers or validated medical electronic sphygmomanometers should still be used as the standard.

It is recommended to use the physical examination treasure as a daily blood pressure trend monitoring tool and regularly compare the measurement results with medical institutions. When abnormal fluctuations are detected, three consecutive measurements should be taken and the average value should be taken. The measurement time and status should be recorded. Hypertensive patients should undergo professional equipment calibration measurements at least once a week to avoid relying solely on home devices to adjust treatment plans. When purchasing, identify the registration certificate number of the medical device, prioritize the upper arm design product, and conduct professional calibration and maintenance every year.
