1. Necessity of Omron Blood Pressure Monitor Calibration
As a common medical device, Omron blood pressure monitors are widely used in homes and medical institutions. However, like any measuring instrument, Omron blood pressure monitors also need to be calibrated regularly to ensure the accuracy of measurements.
The accuracy of blood pressure monitors is crucial for the prevention and treatment of diseases such as hypertension. Inaccurate measurement results may lead to incorrect diagnosis and treatment, which will have a serious impact on the patient's health. According to medical research, even a small change in blood pressure can have a significant impact on the body. For example, if blood pressure rises by 10 mmHg, the risk of cardiovascular disease may double. Therefore, accurate blood pressure measurement is the key to preventing and treating diseases such as hypertension.
After long-term use, the Omron blood pressure monitor may have measurement errors due to various factors. For example, the aging of the sensor, changes in battery power, the influence of ambient temperature and humidity, etc. may cause inaccurate measurement results of the blood pressure monitor. In addition, if the blood pressure monitor is hit or vibrated during use, its measurement accuracy may also be affected.
In order to ensure the measurement accuracy of the Omron blood pressure monitor, regular calibration is essential. Calibration can be completed by comparing measurements with a standard blood pressure monitor. Generally speaking, it is recommended to calibrate the Omron blood pressure monitor every six months to one year. If the measurement results of the blood pressure monitor are found to be significantly different from those of other reliable measuring devices, or if abnormal conditions occur during use, calibration should be carried out in a timely manner.
In short, calibration of Omron blood pressure monitors is an important measure to ensure measurement accuracy, which is of great significance for the prevention and treatment of diseases such as hypertension.
2. Calibration method
(I) With the help of a standard sphygmomanometer
Prepare a standard sphygmomanometer with a known accurate blood pressure value, place the standard sphygmomanometer and the Omron sphygmomanometer in the same location, and ensure that the measurement environment of the two is the same. According to the instruction manual of the Omron blood pressure monitor, use a standard blood pressure monitor to measure the blood pressure value, and compare this value with the value measured by the Omron blood pressure monitor. If there is a large difference between the two, calibration is required. For example, the blood pressure value measured by the standard blood pressure monitor is 120/80mmHg, while the result measured by the Omron blood pressure monitor is 130/85mmHg, which is a large difference. At this time, the Omron blood pressure monitor needs to be calibrated and adjusted.
(II) Operate according to the instruction manual
Before formal calibration, we should first read the manual of the equipment carefully to understand its operation method and calibration method. Generally speaking, calibration needs to be performed in a specific environment, for example, the temperature should be between 10℃ - 40℃, the humidity should be between 30% - 85% RH, and a special calibration instrument should be used. When calibrating, we need to follow the instructions to adjust until the reading matches that of the standard blood pressure monitor. For example, some models of Omron blood pressure monitors require entering a specific menu mode and pressing a specific button to perform calibration operations.
(III) Contact the manufacturer or place of purchase
Omron blood pressure monitors are usually not self-calibrated. If you suspect that the electronic blood pressure reading is inaccurate, you can compare it with the value measured by the mercury sphygmomanometer. If the difference is more than 20 mmHg, you can consider that the value is inaccurate. It is recommended to go to the place of purchase or contact the manufacturer for calibration. When measuring blood pressure, pay attention to the tightness of the cuff. The tightness should be such that two fingers can be inserted after the cuff is fixed. When comparing with the mercury sphygmomanometer reading, pay attention to measuring the blood pressure on the same upper arm.
(IV) Setting Units
It is very important to set the unit of the Omron blood pressure monitor. Generally, there are two units, millimeters of mercury (mmHg) and kilopascals (kPa). The most commonly used unit in life is the millimeters of mercury. Different models of blood pressure monitors have different methods for adjusting units. There are two commonly used methods. One is to turn off the blood pressure monitor, long press the key for setting the time, and two 0s will be displayed on the screen. At this time, press the up or down key of the blood pressure monitor, and the screen will become 4 0s. Then, after shutting down and restarting, the blood pressure monitor unit will be adjusted to mmHg. Another method is to press and hold the start/stop button after turning off the power until there is no decimal point under all the zeros on the display. Then you can release it. At this time, the unit has been converted from one to another.
3. Calibration Precautions
In the process of calibrating the Omron blood pressure monitor, there are many things to pay attention to to ensure the accuracy and effectiveness of the calibration.
First of all, the operating specifications are crucial. In every step of the calibration, you must strictly follow the requirements of the instructions. For example, when connecting a standard blood pressure monitor to an Omron blood pressure monitor, make sure the connection is stable and avoid looseness or poor contact. When adjusting the reading of the blood pressure monitor, be careful and do not make too large adjustments each time to avoid over-adjustment. If you are not familiar with the calibration method, do not try it casually. It is recommended to seek help from a professional.
Secondly, when measuring blood pressure, the cuff should be moderately tight. As mentioned earlier, the cuff should be tight enough to fit two fingers after it is fixed. If the cuff is too tight, the measurement result will be too high; if the cuff is too loose, the measurement result will be too low. When measuring blood pressure with an Omron blood pressure monitor, make sure the cuff is properly tied to the upper arm and in the right position, not too high or too low.
At the same time, pay attention to measuring the blood pressure on the same upper arm. When comparing with the mercury column blood pressure reading, you must measure the same upper arm to ensure the accuracy of the comparison. If there is a difference in blood pressure between the two upper arms, the calibration result may be inaccurate.
In addition, during the calibration process, ensure that the environment is stable. Avoid wind, vibration or other interference factors, and it is best to calibrate in a quiet room. The stability of the environment has an important impact on the accuracy of the sphygmomanometer. If the environment is unstable, it may cause the sphygmomanometer readings to fluctuate, affecting the calibration effect.
Finally, remember the calibration frequency. Generally speaking, it is recommended to calibrate the Omron blood pressure monitor at least once a year. If it is used frequently or in a harsh environment, it may need to be calibrated more frequently. Regular calibration can ensure that the blood pressure monitor always maintains accurate measurement performance and provides us with reliable health data.
In short, when calibrating the Omron blood pressure monitor, pay attention to the operating specifications, cuff tightness, measuring the blood pressure on the same upper arm, environmental stability and calibration frequency to ensure the success of the calibration and the accuracy of the blood pressure monitor.
