Common blood pressure measurements include electronic blood pressure monitor and mercury sphygmomanometers. Many patients have a question that why do doctors like to use mercury blood pressure monitor? It is said that the electronic sphygmomanometer is inaccurate, is it really the case?

Mercury sphygmomanometer is about to be eliminated from the market

In china, mercury blood pressure monitor will be stop produce in 2026, it is mainly because the mercury is toxic and will cause environmental pollution. It will be meaningless if we still doubt whether the electronic blood pressure monitor is accurate or not in the future, because there will be only electronic blood pressure monitor on the market.

This doubt is understandable, because sometimes the results of two measurements are very different when use an electronic blood pressure monitor for twice blood pressure measurements, which inevitably makes people doubt the accuracy of the electronic digital blood pressure monitor.

Actually, if the mercury blood pressure monitor is used in an incorrect measurement method, it will also lead to errors, which is why many people prefer to believe the mercury blood pressure monitor used by doctors.

Whether the electronic blood pressure monitor is accurate or not?

1. Principle: electronic blood pressure monitor is adopt oscillographic method, which measures the blood pressure value by measuring the vibration of the blood vessel wall during blood flow.

2. Measurement value: The measurement result of the electronic blood pressure monitor is accurate to one digit. Unlike mercury blood pressure monitor, it only reads even numbers, not odd numbers.

3. Advantages: electronic blood pressure monitor is a new type of blood pressure monitor, which is simple and convenient to measure, can be operated by anyone, have no risk of mercury leakage.

4. Disadvantages: The quality of some brands of sphygmomanometers is really not up to the standard, which has troubled everyone and caused many people to distrust the digital blood pressure monitor.

Measuring method of electronic blood pressure monitor

3. The upper arm should be at the same level as the heart.

4. In the process of automatic pressure measurement, patient should not move, otherwise the false wave caused by muscle movement will make the pressure measurement fail.

5. The interval between the two measurements shall be more than 3 minutes, and the body position shall be consistent.

Reasons for inaccuracy of electronic blood pressure monitor

1. Improper operation by users will cause large discrepancy in measurement result.

2. There is a problem with the accuracy of the machine. It is best to choose blood pressure monitor with large brands and good reputation. Such as Pangao blood pressure monitor.
