Blood pressure measurement by hand cuff may not be very accurate, and there may be some deviation in the measurement results.
The blood pressure monitors currently used in clinical practice mainly include electronic sphygmomanometers and conventional mercury sphygmomanometers, in which the cuff plays a very important role, including cuff length and cuff width, which are of great significance to the measurement of blood pressure.
Relying only on the contact area of the bracelet to measure blood pressure, the accuracy of the measured blood pressure is much worse, so the accuracy of the bracelet to measure blood pressure is relatively low.
And the blood pressure bracelet measures the blood pressure of the radial artery, the blood pressure of the radial artery will be affected by a variety of factors, and in the extreme state, it may not be able to effectively reflect the real blood pressure situation, so it is recommended that the measurement of blood pressure is based on the arm sphygmomanometer.
Therefore, the measurement of blood pressure by an arm sphygmomanometer is not very accurate and can only be used as a reference.
