1. Check the Blood Pressure Monitor
Check whether the Blood Pressure Monitor is damaged, worn, or has obvious signs of malfunction.
Confirm whether the battery is fully charged. If it is a plug-in type, check whether the power connection is normal.
2. Calibrate the Blood Pressure Monitor
Perform calibration operations according to the instructions of the Blood Pressure Monitor or the manufacturer's recommendations. Some Blood Pressure Monitors can be calibrated by themselves, while others need to be sent to professional institutions for calibration.
You can contact the manufacturer or after-sales service of the Blood Pressure Monitor to learn the specific methods and locations of calibration.
3. Check the measurement method
Relearn and strictly follow the correct measurement steps and requirements.
Make sure that the subject avoids strenuous exercise, smoking, drinking, coffee or strong tea within 30 minutes before the measurement, and stays calm.
Choose a suitable body position, and the arm is at the same level as the heart during measurement.
Wear the cuff correctly and ensure that the cuff is in the right position and tightness.
4. Replace the Blood Pressure Monitor
If the Blood Pressure Monitor is still inaccurate after calibration and multiple correct measurements, you may need to replace it with a new Blood Pressure Monitor.
5. Comparative measurement
You can use another known accurate Blood Pressure Monitor to measure at the same time and compare the measurement results to determine whether the original Blood Pressure Monitor is accurate.
6. Consult professionals
Consult doctors, nurses or related medical professionals for their advice and help.
