As one of the commonly used medical devices for measuring human blood pressure, the sphygmomanometer has entered the homes of more and more consumers due to its lightweight appearance, easy portability, simple operation, and clear display, and has become a common instrument for home health care of consumers. Faced with a wide variety of electronic blood pressure monitor products on the market, how should consumers choose and buy? The Shandong Consumers Association provides you with tips when purchasing. Please pay attention to the following 4 points.



Consult a doctor or professional before purchasing and fully understand the product before use.



It is recommended that consumers purchase and use it under the guidance of a doctor or professional, and fully understand the product's applicable scope and product contraindications before use to prevent damage to health due to misuse.



Online shopping, choose brand self-operated store (flagship store) to purchase, check the type approval (CPA) mark

It is recommended that consumers go to regular pharmacies or medical device stores. If they choose to buy online, it is best to choose a brand self-operated store (flagship store). Pay attention to check whether the product packaging is complete and the product information is complete. Pay special attention to check whether there is type approval. (CPA) logo and product production license issued by the drug regulatory department to prevent the purchase of fake and shoddy products.



Pay attention to choosing products that suit you



At present, electronic blood pressure monitors are mainly divided into two types: upper arm type and wrist type. Because the upper arm type measures the brachial artery of the upper arm, the measurement accuracy is relatively high and is not restricted by the user group. The wrist type is small and easy to carry, and is suitable for young and middle-aged people who often go on business trips and travel without a clear medical history.



Focus on practical functions



Consumers should choose based on the fundamental need of measuring blood pressure, and then consider the needs of other functions of the blood pressure monitor, and should not blindly pursue "high technology".

In recent years, with the popularity of electronic blood pressure monitors, self-testing of blood pressure at home has attracted more and more attention. Self-measurement of blood pressure is convenient, easy, and cheap. Patients can measure it at any time, understand their blood pressure in a timely manner, improve treatment compliance, and avoid high blood pressure measurements caused by mental stress. Although electronic blood pressure monitors have many benefits, they will inevitably encounter many problems during use. We have collected some frequently asked questions and provided answers for readers.



1. Is the electronic blood pressure monitor affected by seasons? When using an electronic sphygmomanometer, the blood pressure is normal when measured in summer, but high when measured in winter. Will the accuracy of the electronic sphygmomanometer be affected by temperature?

Answer: It is not the electronic blood pressure monitor that is affected by the seasons, but the human blood pressure that is affected by the seasons. Blood pressure will decrease slightly in summer and increase significantly in winter, especially in the elderly. American scholars have found that systolic blood pressure and diastolic blood pressure are 12 mm Hg and 5.5 mm Hg respectively higher in winter than in summer. Therefore, when the weather gets cooler and the temperature drops, the type or dose of antihypertensive drugs should be appropriately increased under the guidance of a doctor based on blood pressure measurements.



2. Does the cuff height affect the measurement results? The product description of the electronic blood pressure monitor reads: Place the cuff at the level of the heart for measurement. Why do electronic blood pressure monitors have strict requirements on measurement locations?Answer: The height of the cuff should be at the same level as the heart. If the cuff position is too high, the measured blood pressure value will be low; if the cuff position is too low, the measured blood pressure value will be high. In addition, when measuring blood pressure, it is best for the subject to sit in a sitting position with his back leaning against the back of the chair, and then wrap the cuff around his bare left upper arm for measurement.



3. What should I do if the self-measured blood pressure is inconsistent with the blood pressure measured by the hospital? When using electronic blood pressure measurement at home, the systolic blood pressure was only 135 mmHg, but when I went to the hospital for a physical examination, the blood pressure was 140 mmHg. Is the electronic blood pressure monitor inaccurate? Is this considered high blood pressure?

Answer: The 2010 "China Guidelines for the Prevention and Treatment of Hypertension" pointed out that using an upper-arm fully automatic or semi-automatic electronic sphygmomanometer that meets relevant standards, a home self-measured blood pressure of 135/85 mmHg is equivalent to a clinic blood pressure of 140/90 mmHg. Therefore, a blood pressure of 135 mm Hg measured multiple times at home is considered high blood pressure.



4. Why is it recommended to take the average value for electronic blood pressure monitors?

Answer: A normal person's blood pressure reaches its peak between 8-10 am and 4-6 pm. At night, the blood pressure drops by more than 10% compared with the daytime level. Therefore, the blood pressure at a certain moment cannot represent the overall blood pressure level. It is recommended to take the average of multiple measurements as a reference value for blood pressure levels. Or choose an electronic blood pressure monitor with memory function to overcome the errors caused by the above problems. Some arm blood pressure monitors have multiple memory functions to facilitate calculation of average values. While recording the blood pressure value, you should also record the date, time, location and activity of the measurement for your own and your doctor's reference.

Expert's Guide: How to Accurately Use an Electronic Blood Pressure Monitor

In recent years, with the popularization of electronic blood pressure monitors, home self-monitoring of blood pressure has become increasingly important. Self testing blood pressure is convenient, feasible, and inexpensive. Patients can measure their blood pressure at any time, timely understand their own blood pressure situation, improve treatment compliance, and avoid high blood pressure measurement values caused by mental stress. Although electronic blood pressure monitors have many benefits, it is inevitable to encounter many problems during use. We have collected some frequently asked questions and provided readers with answers.

Is electronic blood pressure monitors affected by seasons? Using an electronic blood pressure monitor, when measured in summer, blood pressure is normal, but when measured in winter, blood pressure is higher. Will the accuracy of an electronic blood pressure monitor be affected by temperature?

Answer: It's not that electronic blood pressure monitors are influenced by seasons, but rather that human blood pressure is influenced by seasons. Blood pressure will slightly decrease in summer and significantly increase in winter, especially for the elderly. American scholars have found that systolic and diastolic blood pressure in winter are 12 millimeters and 5.5 millimeters of mercury higher than in summer, respectively. Therefore, when the weather cools down and the temperature drops, blood pressure measurements should be combined and the type or dosage of antihypertensive drugs should be appropriately increased under the guidance of a doctor.

Does the height of the cuffs affect the measurement results? The electronic blood pressure monitor product description states: The cuff is placed at the heart level for measurement. Why do electronic blood pressure monitors require strict measurement positions?

Answer: The height of the cuff should be at the same level as the heart. If the cuff position is too high, the measured blood pressure value will be lower; If the cuff position is too low, the measured blood pressure value will be higher. In addition, when measuring blood pressure, it is best for the subject to sit in a sitting position, lean their back against the back of the chair, expose their left upper arm, and wrap a cuff around it for measurement.

What should I do if the blood pressure measured by myself is inconsistent with that measured by the hospital? When using an electronic blood pressure monitor at home, the systolic blood pressure is only 135 millimeters of mercury, but when going to the hospital for a physical examination, the blood pressure is 140 millimeters of mercury. Is the electronic blood pressure monitor inaccurate? Does this situation really count as hypertension?

Answer: In the 2010 Chinese Guidelines for the Prevention and Treatment of Hypertension, it was pointed out that using an upper arm fully automatic or semi-automatic electronic blood pressure monitor that meets relevant standards, the self measured blood pressure at home is 135/85 mmHg, which is equivalent to clinic blood pressure of 140/90 mmHg. Therefore, having blood pressure measured multiple times at home at 135 millimeters of mercury is also considered high blood pressure.

Why is it recommended to take the average value for electronic blood pressure monitors?

Answer: The blood pressure of a normal person reaches its peak from 8-10 am and 4-6 pm, and decreases by more than 10% at night compared to during the day. So, the blood pressure at a certain moment cannot represent the overall blood pressure level. It is recommended to take the average of multiple measurements as a reference value for blood pressure levels. Alternatively, choose an electronic blood pressure monitor with memory function to overcome the errors caused by the aforementioned issues. Some arm style blood pressure monitors have multiple memory functions, making it easy to calculate the average value. At the same time as recording blood pressure values, the measurement date, time, location, and activity should also be recorded for reference by oneself and the doctor.
