Diseases such as diabetes and hyperlipidemia can accelerate the process of arteriosclerosis, which in turn may cause peripheral circulation disorders in patients. There can be a significant difference between the blood pressure measurements taken at the wrist and upper arm in these patients. It is recommended that these patients, as well as elderly individuals, choose an arm-style electronic blood pressure monitor. Before purchasing, it's advisable to take actual measurements and select the one whose readings are closest to your usual blood pressure values. Additionally, people with weak pulses, very low blood pressure, or those in certain emergency situations should not use electronic blood pressure monitors.
If used correctly, an electronic blood pressure monitor should be just as accurate as traditional mercury column or gauge-type blood pressure monitors. However, the sensitivity of its pulse sensor might lead to measurement errors. The cuff and its positioning, movement, friction, surrounding noise, mechanical or circuit failures can all affect its sensitivity. Electronic blood pressure monitors have been widely adopted abroad, while their use in China has only recently begun. There aren't many domestically produced electronic blood pressure monitors; most are imported from abroad. With advancements in electronic technology, overseas electronic blood pressure monitors are rapidly updated and upgraded, having evolved to the fourth generation. When selecting one, it's important to gather more related product knowledge to facilitate better comparison and selection.
